The Borax Method of Gold Extraction for SmallScale Miners

gold miners Smallscale miners Some SSM communities continue finetuned each step of the process from crushed ore to gold pellet. Their method is as follows: The first step after crushing the ore is milling. This takes place in metal drums with hard metal rods or balls. No mercury is added. After milling, the groundup ore is flushed into a

MercuryFree Gold Extraction Using Borax for SmallScale

Smallscale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health

Mercuryfree, smallscale artisanal gold mining in

The overwhelming majority of artisanal and smallscale gold miners utilize mercury to separate gold from the unwanted gangue materials (Telmer and Veiga, 2009). Miners use rudimentary tools to mine and process ore, adding elemental mercury to amalgamate fine gold particles after grinding the ore in a ball mill and concentrating by panning.

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ''see'' the gold in the leaching process.
