Gold mining produces devastating amounts of waste! On average, only 0.00001 of the ore that is mined is refined into gold. The remaining 99.9999 is waste - much of it is highly toxic. Low-grade gold ore is often mixed with sodium cyanide to dissolve the gold. Cyanide is a highly poisonous chemical that destroys ecosystems if not contained.Dec 16, 2019 One tonne of e-waste contains gold than 17 tonnes of ore, making it a rich alternative to traditional mining. Recycling precious metals and minerals from used electronics can help make today's consumption patterns environmentally sustainable. About US$500 billion worth of natural resources are reportedly extracted each year in Africa.
Research and development of soil binders and vegetation with a broad pH-range tolerance would be beneficial. Gold Most of -the wastewater from gold mining and beneficiation operations is discharged into a tailings pond, then recycled to the mill or discharged into a watercourse. Solid waste is usually discarded into the same pond.The historic waste sites are primarily contaminated with waste rock, tailings, sludges, and other mining waste products. Kennecott is proceeding expeditiously to clean up these sites as part of the overall modernization effort.
