Introduction Heavy metals such as lead‚ zinc‚ copper‚ can often be found in industrial wastewater and their discharge to the environment poses a serious threat due to their acute toxicity to aquatic and terrestrial life which includes humans. As a result of increasing industrialization more heavy metals are continually released to the environment and this has prompted environmental engineers and scientists to think of better methods by which heavy metal-bearing wastewaters can

harmful toxic wastes are occurred. Thus gold mining has drastic effects on water‚ earth and air. Firstly‚ gold mining can has devastating effect on water because of leaked chemicals. Cyanide and some heavy metals are used in process of gold mining. If gold mine leaks cyanide or other heavy metals‚ these chemicals can react with water and produce acidic water.
