As global demand for minerals continues, especially for technologies driving the transition towards sustainability in 2026, responsible mining practices and environmental stewardship are more critical than ever.

Habitat Destruction and Land Degradation

Open-pit mining, a common method for extracting near-surface mineral deposits, involves removing large volumes of overlying rock and soil. This process leads to direct habitat destruction, altering landscapes, disrupting natural drainage patterns, and impacting biodiversity. The creation of mine pits, waste rock dumps, and tailings storage facilities permanently changes the topography and can lead to soil erosion and sedimentation in nearby water bodies, affecting aquatic life.

Water Contamination

Mining activities can severely contaminate water resources through several mechanisms:

• Acid Mine Drainage (AMD): When sulfide minerals (like pyrite) are exposed to air and water, they oxidize, producing sulfuric acid. This acidic water can leach heavy metals (e.g., lead, zinc, copper, cadmium) from the surrounding rock, creating highly toxic solutions that can pollute rivers, lakes, and groundwater. This has been a significant issue in historically mined areas like Kabwe.
• Heavy Metal Leaching: Even without acid generation, the breakdown of ore minerals and waste rock can release toxic heavy metals directly into water systems.
• Sedimentation: Erosion from mine sites and tailings can increase sediment loads in rivers, impacting aquatic habitats, fish populations, and water quality for downstream users.

Air Pollution

Dust generated during mining, hauling, and processing operations can release particulate matter and potentially toxic elements into the atmosphere. Activities like smelting can also release sulfur dioxide (SO₂) and heavy metals, contributing to air pollution and acid rain, impacting vegetation and human respiratory health.

Impact on Biodiversity

The combined effects of habitat loss, water and air pollution, and soil contamination can lead to significant declines in biodiversity. Sensitive species may be unable to survive in altered or polluted environments, leading to reduced species richness and abundance. The disruption of food chains and the bioaccumulation of toxins (like lead in Kabwe) can have cascading effects throughout the ecosystem.

Human Health Impacts

As exemplified by Kabwe, historical mining can leave a legacy of environmental contamination that directly impacts human health. Exposure to heavy metals through contaminated soil, water, or dust can lead to serious health issues, including developmental problems in children, neurological damage, and organ damage in adults. Addressing these legacy issues requires extensive environmental remediation and public health interventions.

The study of minerals earth and life science compels us to consider the full lifecycle of mineral resources—from extraction to end-use and disposal—and to develop strategies for mitigating negative impacts.
