Cyanide Use in Gold Mining - Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring. What are the dangers of using cyanide? Cyanide

CYANIDE RECOVERY COST EFFECTIVENESS IS WHY

the cyanide solution is treated with sulphide ions and sulphuric acid to yield a pH of 4 - 5. Under these conditions, the base metals precipitate from solution as sulphides (e.g. Cu 2 S or ZnS), leaving cyanide in solution as HCN gas. The metal sulphide precipitate is flocculated, thickened and filtered, to produce a saleable concentrate.
