ACID MINE DRAINAGE

REDUCING THE RISKS IN MANAGING ACID MINE WATER

Water is an essential part of life, but it can also be a major pollutant. When water flows through active or abandoned mine sites, it can become polluted by the material being mined. Acid Mine Drainage (AMD) is the outflow of acidic water as a by-product of mining operations and, in most cases, the highly toxic water has the potential to poison downstream waters and destroy already fragile ecosystems.

Sulfuric acid mine water is produced when water interacts with sulphur-bearing materials in the presence of oxygen and common bacteria. The acidic water formed by this process can dissolve many metals in bioavailable forms, posing a threat to humans and wildlife. If Acid Mine Drainage gets into surface waterways, both the acidity and metal content can produce significant environmental problems over large distances. Acid mine drainage is a serious problem that needs to be addressed in order to protect our waterways and the people and animals that depend on them.

Effective and sustainable groundwater management of this toxic outflow is traditionally expensive but critical in any minerals processing application with leachates and sulphidic mine wastes posing a significant commercial and sustainability risk for mining operators. With elevated concentrations of sulphate and soluble metals in acid mine drainage water including copper, cobalt, aluminium, iron and manganese offering the potential to affect domestic water supplies and broader ecosystems, the imperative sits with industrial leaders to implement long-term, sustainable drainage solutions.

Acid Mine Drainage Water Evaporation

ACID MINE WATER SOLUTION

MINETEK has developed a cost-effective method to manage acid mine drainage with our wastewater evaporation solutions used by leading miners around the world. Our globally-patented, low-maintenance technology has been built specifically for operation in harsh and corrosive conditions, requires no pre-treatment and has been proven to be more effective than traditional water treatment methods.

With the capability to evaporate water with high levels of Total Dissolvable Solids (TDS) and Total Suspended Solids (TSS) and pH range as low as 1.8 and as high as 14, MINETEK's water evaporation solutions offer versatility and a cost-effective solution to managing Multi-Aquifer Well (MAW).

MINETEK initially provided products for heavy mobile equipment noise abatement at the New Acland Mine. These installations have been very successful and prompted the contracting of MINETEK to conduct a full mobile fleet and fixed plant noise monitoring assessment at the Acland mine site.
