The use of cyanide in gold mining
In recent years the use of cyanide in gold mining has become the dominant means by which gold is extracted from a body of ore The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body’s gold In contrast, leaching finely ground ore with cyanide can recover up to 97 per cent of the ore body These illegal gold miners use mercury to extract gold, leaching the toxic chemical into the air and water About 1,000 tons of mercury is released into the environment every year by the 15 million artisanal gold miners around the world Mercury is harmful to human health, damaging the kidney, liver, lungs, colon, heart and the immune systemTips on Reducing The Impact of Gold Mining And Processing Posted 30 June, 2021 13:00 Costs in the gold mining industry increased for the second consecutive quarter in Q1’21, with the global average Allin Sustaining Cost (AISC) up by 5% qoq to US$1,048/oz, reaching its highest level since Q2’13 This, combined with a 4% fall in the average quarterly gold price, resulted in a 14% drop in AISC Rising gold mining costs Q1'21 Gold Focus World Gold
