By upgrading the wastewater treatment plant, reviewing operations practices and training a dedicated local team, Veolia allowed AngloGold Ashanti to maintain and improve its operations.

Gold Mining Wastewater Solutions Pollution to Water

Gold extraction process requires heavy water usage, and as there are dangerous chemicals that pollute the water (cyanide, sulfates) that can also result the creation of Acid Mine Drainage, there is a need to “contain” or purify this water. A mine’s wastewater is contaminated by heavy metals, and chemicals such as cyanide or sulfates. All these pollutants require thorough treatment so as to not harm the

Mine Water Treatment Solutions for Discharge and Re-Use

A number of water treatment systems are in place, mainly in the gold, coal, nickel, and copper industries. The systems are installed at operational, industrial scale plants, where mine drainage or pit water, waste water from tailing storage facilities, and even “produced water” from coal seam methane production are treated.

In many mines throughout the world, waste rock and tailings are disposed of separately to form waste dumps and tailings dams. At Waihi the situation is unusual, in that waste rock is used to form engineered embankments that are progressively raised in order to ‘keep up’ with tailings production. This allows for sufficient storage capacity to ensure that the water within the tailings pond
