Chemical Reactions In Mining by Michaela Baker

When mining begins, chemicals are leaked into the ground and water, contaminating everything. Not to mention the fact that if chemicals get into the water shed, it can affect thousands of people, plants, and animals. Why are These Reactions and Cyanide Used? Cyanide is used in the process of separating the gold and silver particles from the ore.

Chemicals Used in Mining Hesperian Health Guides 16-06-2020  Cyanide is often spilled into waterways during gold mining, and when ponds filled with mine wastes burst and spill. Mining companies say that cyanide in water quickly becomes harmless. But this is true only when there is lots of sunlight and oxygen.

Gold cyanidation Wikipedia

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au (s) + 8 NaCN (aq) + O 2 (g) + 2H 2 O (l)→ 4 Na [Au (CN) 2 ] (aq) + 4 NaOH (aq) In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au (CN)− 2 ion.

Acid mine drainage Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

Extracting Gold HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or

Gold Ore an overview ScienceDirect Topics

Mining requires a large amount of water for floatation, heap leaching of copper and gold ores, dust suppression, equipment cooling, slurry transport, and human needs at the mining sites [46]. However, mining sites are often far from the water sources and it is not easy to secure the water supply. Therefore, the contamination of water that occurs during the processing requires treatment before

Environmental Impacts of Gold Mining Brilliant Earth

Iron sulfides (often called “fool’s gold”) in the rock can react with oxygen to form sulfuric acid. Acidic water draining from mine sites can be 20 to 300 times more concentrated than acid rain, and it is toxic to living organisms. The dangers increase when this acidic water runs over rocks and strips out other embedded heavy metals. Rivers and streams can become contaminated with metals
