Mining has been around for years and consistently received a negative score for the environment. The industry has also been notorious for creating toxic working environments while destroying local communities and ecosystems. It’s a long list of evils.
While conditions have improved significantly over the years, the mining industry never seemed to lose its bad reputation. This has necessitated more rules and regulations to ensure the mining process is safe and abides by existing laws.
Mining companies are increasingly switching to more sustainable methods to protect the environment because it makes more economic sense.
There are several reasons why mining is becoming more sustainable.
First, mining executives and consumers are increasingly aware of the need to protect the environment. As such, there is more pressure on mining companies today to slash their carbon emissions and minimize damage to local ecosystems.
Second, emerging technologies make it feasible to have more sustainable mines and mining operations.
Mining companies have realized that Eco-friendly mining is good at reducing their environmental impact and improving their public image.
So, what’s all the beef with mining, and how can we make it more environmentally friendly?
Environmentally friendly mining
Environmentally friendly mining is the practice of extracting minerals and other materials in a way that minimizes the negative environmental impact of the entire operation.
In many cases, this means using cleaner technologies to reduce the release of pollutants, minimizing the use of water and energy, and maximizing the reuse and recycling of materials.
Sometimes, it may also mean locating mines in areas with lower environmental impact.
However, environmentally friendly mining is not just about reducing pollution but also about ensuring that the local communities and ecosystems can continue to thrive even after the mine has closed.
This requires careful planning and monitoring to ensure that any negative impacts are minimized and the positive effects maximized. When done correctly, environmentally friendly mining can be a critical tool for sustainable development.
The issues with mining
Mining is a process of extracting valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. These deposits form a mineralized package of economic interest to the miner.
Ores recovered by mining include metals, coal and oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
We require mining to extract any materials that cannot be grown through agricultural processes or created artificially in a laboratory or factory. Mining in the broader sense includes extracting non-renewable resources such as petroleum, natural gas, or even water.
Mining is the only major sector of the economy that is not sustainable. It uses up finite resources and, in turn, pollutes and destroys ecosystems.
The adverse effects of mining are far-reaching and often irreversible. The process usually involves clearing large areas of land, which can damage natural habitats, cause deforestation, and lead to soil erosion.
There is also evidence that mining causes global warming through excessive CO2 emissions, biodiversity loss, and accelerated erosion. It also poisons the land and water table with toxic chemicals and heavy metals, which leak into our drinking water supply.
These pollutants can cause respiratory problems, skin irritation, and even death. As a result, it is critical to carefully consider the environmental impact of any proposed mining project.
Strides in sustainable mining
One promising green mining technology is the use of bacteria to extract metals from ore.
This “bioleaching” approach takes advantage of the fact that some bacteria can chemically break down minerals and release metals into solution. This technology is already being used on a small scale to extract copper, gold, and uranium, and we can potentially use it for a wider range of metals in the future.
Another area of active research is the development of “green” extraction methods that do not use toxic chemicals or generate hazardous waste.
One example is the use of enzymes to selectively dissolve metals from ore. This approach has the potential to be far less energy-intensive and environmentally damaging than traditional mining methods.
There’s also interest in reusing and recycling metals mined from the earth. In many cases, it is possible to recycle metals multiple times before they need to be extracted from the ore.
For example, steel can be recycled indefinitely without losing any of its properties. By increasing the recycling rate of metals, we can reduce our reliance on mining and lower our environmental impact.
Deep sea mining also looks like a promising alternative, albeit with some obvious drawbacks.
This relatively new technology involves pumps that draw water from depths of up to 4,000 meters, yielding small amounts of minerals such as copper and manganese.
The advantages of deep-sea mining include a lower carbon footprint than other mining operations and reduced environmental impact because there is no need to remove topsoil or drill into rock formations.
However, without safeguards, there’s the potential to destroy or destabilize marine ecosystems.
While there is still some way to go, the trend is definitely towards more environmentally friendly mining practices.
What can you do?
- Reduce, reuse, recycle.
- Choose products that have been certified as mined using sustainable practices.
- Pressure your elected representatives to support policies that encourage sustainable mining practices.
- Support companies and organizations working towards more sustainable mining practices.
