The negative impact of mining

Oct 21,2023 - Last updated at Oct 21,2023

The mining industry, while a crucial driver of economic development and natural resource extraction in some countries, where concentrations of minerals are feasible, often comes at a significant cost to environmental sustainability. The extraction of minerals, metals and fossil fuels, coupled with the associated activities such as de-forestation, burning gas flares and clearing the topsoil can have far-reaching and detrimental effects on ecosystems, biodiversity, air and water quality and the overall health of the planet. This article explores the negative environmental impacts of mining and the imperative need for more sustainable practices within this industry on a world scale, particularly in underdeveloped countries where laws and regulations are flexible.

One of the most immediate and evident impacts of mining is habitat destruction. Mines, especially open-pit, can alter landscapes beyond recognition. Forests are cleared, rivers are rerouted and ecosystems and groundwater are disrupted and polluted. This destruction threatens countless species, many of which are already endangered. Habitats are destroyed or fragmented, making it difficult for many species to survive. 

Dust and emissions from mining operations can degrade air quality in surrounding areas. Particulate matter and emissions of airborne pollutants can contribute to respiratory problems, cardiovascular effects and other health issues. The removal of topsoil and the exposure of underlying mineral deposits can result in soil erosion and environmental degradation. This can lead to reduced agricultural productivity and further habitat loss. Environmental degradation in Jordan is around 3 per cent of the GDP, in Egypt it is around 5 per cent, which accounts to hundreds of millions of dollars.

Mining often requires the clearing of large areas of forest. This not only diminishes vital carbon sinks but also disrupts ecosystems and contributes to exacerbating the impact of climate change. The extraction of fossil fuels, such as coal, oil, and natural gas, is a major driver of climate change. Mining, transportation, and processing of minerals and metals often require substantial energy inputs, which are typically derived from fossil fuels. This further exacerbates the carbon footprint of the mining industry.

Mitigating the environmental impact of mining is challenging as the global demand for minerals and metals continues to rise as populations grow, technologies advance and economic growth swells by the year. Profit-driven motives often prioritise short-term gains over long-term sustainability. This can lead to inadequate environmental precautions as some areas lack robust environmental regulations or struggle with corruption, allowing mining companies to operate with less caution towards environmental degradation. Therefore, strengthening environmental regulations is crucial. Governments must hold mining companies accountable for their environmental responsibilities, including habitat restoration and pollution control. 

Innovations in mining technologies can reduce environmental impacts. For example, advanced extraction methods and recycling techniques can minimise resource waste and pollution. In-situ Mining is especially valuable for extracting minerals. Instead of physically removing large quantities of ore, in-situ mining involves injecting a leaching solution which dissolves the desired minerals, then pumped to the surface for processing. In-situ mining minimises the need for extensive excavation and the associated disturbances, reducing the environmental footprint, energy consumption, and waste production. 

Effective reclamation and rehabilitation of mining sites can help restore ecosystems and minimise long-term environmental harm. This should be an integral part of mining plans. Transitioning mining operations to renewable energy sources rather than fossil fuels can reduce carbon emissions associated with the industry. Embracing a circular economy approach, which focuses on recycling and reusing materials, can also reduce the need for new mining operations.

In conclusion, the negative environmental impact of mining is a significant challenge for global environmental sustainability. While the demand for minerals and metals continues to rise, it is imperative that the mining industry, governments, NGOs, the United Nations and society as a whole take proactive steps to mitigate these impacts. Sustainable innovative mining practices, stringent regulations, and a shift towards responsible sourcing are critical components of a more environmentally sustainable future.
