Direct Smelting: An Alternative to Mercury Use in Gold
In over 80 developing countries in the world, mercury is the artisanal gold miner’s go-to for separating gold from concentrated ore. Due to a lack of resources and available alternatives, mercury is often handled with bare hands, and in the effort to amalgamate gold, much of it escapes into waterways and soil where it enters the food chain. Most dangerously, the amalgamate is burned, and

Mercury Free Gold Processing
Mercury Free Gold Processing. By Kevin Telmer
Stamp mills used mercury to extract gold from the crushed rock, increasing the yield. Crushed gold ore was combined with liquid mercury. The gold stuck to the mercury and this slurry was then boiled, evaporating the mercury, leaving behind the gold. Some mercury boiled off into the air, and some was recaptured and used again. About 10-25% of all mercury used was lost in tailings.
