To understand environmental science, you need to gain an insight into the intricate process of mineral supply, which fundamentally shapes our physical environment and economies.
Mineral supply refers to the availability and accessibility of valuable geological resources, including common rocks and precious ores, that can be extracted and economically exploited.
Minerals, in their different forms, play a crucial role in our physical environment. Their interaction with different atmospheric, hydraulic, and organic elements make up Earth's lithosphere and define the quality of the soil, air, and water, which directly influence biodiversity and the human living conditions.
For example, consider the role of calcium, a common mineral, in our ecosystem. It is a vital component in the formation of coral reefs, which offer a habitat to various marine life forms and also protect coastal areas by reducing the power of waves. Consequently, the supply of calcium significantly influences marine biodiversity and the security of coastal localities.
Several factors shape the mineral supply and demand chain within the environmental framework. They are rooted in geological, geographical, economic, technological, and political determinants.
Here is an outline of a few key factors:
Each factor plays an integral role in shaping the supply of minerals in specific locations, which results in notable disparities in regional mineral wealth.
For instance, although Africa holds around 30% of the world's total mineral reserves, the region lags in mining infrastructure and lacks expertise. Consequently, despite its rich mineral repositories, Africa's contribution to global mineral supply is not proportional to its geological wealth. This complex scenario illustrates the pivotal role of the intersection of different factors beyond mere geological luck.
Mineral extraction, a key aspect of mineral supply, significantly impacts the environment. This process entails the exploitation of mineral-rich areas, leading to changes in the physical landscape and potential harm to habitats and ecosystems.
Mineral resource management primarily works to balance the benefits derived from mineral extraction and its environmental consequences. However, unregulated or poorly managed mineral extraction can lead to an array of environmental issues.
Mineral resource management refers to the efficient and responsible regulation of extraction, usage, and protection of precious geological resources.
For instance, the extraction process often involves clearing large areas of land, which could lead to deforestation, loss of biodiversity, and disruption of ecosystems. Besides, it can contribute to water, soil, and air pollution when waste and by-products from mining activities are improperly disposed of.
Here are some more potential effects on the environment:
For example, Gold mining is known for its harsh environmental effects. Cyanide, a toxic chemical used to separate gold from ore, often leaks into nearby water bodies, adversely affecting aquatic life and potentially contaminating local water supplies.
Irresponsible practices in the mineral supply chain, from extraction through to product disposal, can wreak havoc on the environment. These practices often stem from a lack of regulations or poor enforcement of existing laws.
Here's a table detailing the possible effects of these irresponsible practices at different stages of the mineral supply chain:
Extraction | It can lead to land degradation, habitat loss, and water pollution |
Processing | It can generate hazardous waste, contaminate water, and cause air pollution |
Transport | It can contribute to air pollution and carbon emissions and potentially lead to oil or fuel spills |
Usage | It can lead to energy wastage and contribute to greenhouse gas emissions |
Disposal | It can result in landfill accumulation and release harmful substances into the environment |
An infamous instance of irresponsible mineral supply chain practice is the 2015 Samarco mine disaster in Brazil. The collapse of an iron ore tailings dam led to the release of approximately 60 million cubic meters of toxic mud, which killed 19 people, destroyed several towns, and contaminated the Rio Doce river. It's considered one of the worst environmental disasters in Brazilian history.
The relationship between mineral scarcity and environmental conservation is indeed complex. While mineral scarcity could push towards more sustainable mining practices and recycling, it could also lead to more aggressive exploitation of existing resources, thus amplifying the environmental harms.
As reserves of minerals become scarce, the following reactions could be expected:
To reduce dependency on precious but scarce minerals like gold, scientists have been exploring more sustainable alternatives. For example, they are working on a technique to 'grow' gold nanoparticles, which could be used in electronics and other industries, reducing the need for traditional gold mining.
As environmental concerns rise, the focus has naturally shifted towards more sustainable methods of mineral supply. The objective is to meet current demands while ensuring the future availability of resources and minimising the negative impact on the environment.
Sustainable mineral resource management is gaining ground as a crucial area within environmental science. It places an emphasis on responsible mining, waste disposal, and ecological restoration during mineral extraction.
Sustainable mineral resource management entails the efficient and sensible utilisation of mineral resources while prioritising environmental well-being. It involves implementing stringent guidelines and standards to orchestrate extraction and use of minerals, with the least environmental harm.
Here are some techniques for achieving sustainability in mineral resource management:
An exemplar of successful land rehabilitation is the Eden Project in the UK. What was once a depleted china clay pit, has been transformed into a unique ecological paradise with multiple biomes, hosting a rich diversity of plants. The project showcases the potential of rehabilitating mining sites for conservation and educational purposes.
The mineral supply chain, extensive as it is, can deliver ripple effects throughout the global economy and the environment. Embracing sustainability in this chain is of paramount importance, as it can not only conserve precious resources but also reduce negative environmental impacts.
A sustainable mineral supply chain seeks to optimally use every resource throughout the entire life cycle of a product, from extraction, processing and distribution, to usage and disposal. It promotes practices that encourage maximisation of resource value while reducing wastage and environmental harm.
Here are a few ways to implement a sustainable mineral supply chain:
For instance, the "Conflict-Free Gold Standard", developed by the World Gold Council, promotes ethically sourced gold. It aims to ensure that gold mining does not fuel unlawful armed conflict, respects human rights, and contributes to development.
Achieving a balance between mineral supply, demand and sustainability is not a task to be underestimated. It requires careful management of resources, adoption of sustainable practices in extraction and usage, and nurturing a culture that values environmental preservation.
Here are some strategies to maintain this balance:
The implementation of the European Union's "Raw Materials Initiative" in 2008 is a strong case illustrating the effort to balance mineral supply, demand, and sustainability. Focusing on securing a sustainable supply of raw materials for Europe, the initiative highlights the importance of embedding sustainable practices within industry standards, fostering research and innovation, and promoting resource efficiency and recycling.
As Earth's resources are finite, the continuous and accelerated extraction of minerals is leading to a growing concern: mineral scarcity. In this section, you'll learn more about the causes and consequences of mineral scarcity, along with practical strategies and techniques to promote effective mineral conservation.
Mineral scarcity, largely a man-made dilemma, has diverse causes and far-reaching implications. It not only poses a serious threat to various industries, but also has significant environmental implications.
Mineral scarcity refers to the decreasing availability of mineral resources due to over-extraction, inefficient use, and inadequate recycling efforts, making it increasingly difficult to meet global demand.
Let's delve into some of the primary causes of mineral scarcity:
The above causes directly lead to a variety of consequences:
A historical example of the economic and geopolitical tensions caused by mineral scarcity is the 1970s oil crisis. During this period, members of the Organization of Arab Petroleum Exporting Countries (OAPEC) proclaimed an oil embargo, leading to substantial increases in oil prices and major economic disruption worldwide.
In response to burgeoning mineral scarcity, developing effective conservation strategies is essential. The ultimate goal is to ensure that minerals are used wisely and sustainably, to reduce waste, minimise environmental harm, and promote economic stability.
Mineral conservation essentially entails using mineral resources in a way that ensures they last longer and cause minimal harm to the environment. It seeks to strike a healthy balance between mineral extraction, usage, and preservation of the environment.
Here are some viable strategies for effective mineral conservation:
A notable example of a resource-efficient and sustainable practice is the car manufacturer Toyota's highly efficient production system. Also known as the "Toyota Production System", it minimises waste by optimising just-in-time manufacturing processes, thereby reducing the overall resources used in the production line.
Alongside these strategies, a variety of techniques can further aid in effective mineral conservation:
A distinct instance of advantageous policy-making is Sweden's 'Green Industrial Policy'. The policy seeks to structure economic incentives in a way that promotes a greener economy. It includes tax breaks for environmental technology investments and requirements for state-owned companies to be environment-friendly.
The mineral supply chain plays an instrumental role in shaping our environment, economy, and society at large. It describes the complete process associated with mineral commodities, right from discovery of deposits, extraction, refinement, transportation to distribution and end-use.
Behind every mineral we utilise, there is a complex, multi-layered process called the mineral supply chain. Each stage in the chain presents different challenges, necessitates particular expertise, and carries varying degrees of environmental impact.
The mineral supply chain denotes the sequence of procedures followed in delivering minerals from the extraction sites to the end-users. It includes a series of processes: exploration, extraction, mineral processing, refining, manufacturing, and eventually transportation and distribution to the consumers.
Here's a succinct description of each process:
An instance of the mineral supply chain is the diamond industry. Once diamonds are discovered (exploration) and mined (extraction), they are sorted and cut (processing). After that, they're cleaned and polished (refining) before being sold in jewellery stores (manufacturing and distribution) all over the world.
Given the environmental impacts linked with the mineral supply chain, incorporating sustainability and responsible management is of utmost importance.
Making the mineral supply chain sustainable and responsible implies using extraction methods that minimise environmental harm, optimising the use of resources, prioritising the welfare of local communities, and ensuring fair trading practices. Note that the exact strategies might differ depending on the specific mineral in question, local environmental conditions, and socio-economic factors.
Here are some key ways to incorporate sustainability and responsibility into the mineral supply chain:
The 'Fairmined' certification standard for precious metals offers a powerful example of a sustainable and fair mineral supply chain. Under this standard, small-scale mines committed to fair trading practices and environmental protection can achieve certification, allowing their gold to be sold as 'Fairmined'. This not only fosters ethical mining practices but also empowers artisanal miners by connecting them with ethical buyers.
As global mineral demand continues to escalate and resource scarcity looms, the mineral supply chain has a vital role in managing these challenges effectively.
Within the context of resource demand and scarcity, the mineral supply chain can contribute to solutions by optimising resource use, revolutionising extraction and production processes, and fostering a culture of recycling and reusing.
Here are some approaches to achieve this:
A fantastic example of managing resource demand through industrial symbiosis is the town of Kalundborg in Denmark. It is home to several industries, each sharing its waste with others. For example, surplus steam from a power plant is used by a pharmaceutical company and a gypsum board manufacturing facility; a fish farm uses treated wastewater from a pharmaceutical plant, and so on. This synergistic approach has resulted in substantial resource savings.
