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 ...
