In this study, sodium cyanide leaching technology has been used to recover gold from tailings that are used by Mawelo small scale miners, located in Chunya district, Mbeya region, Tanzania. The sample collected was sent for analysis of mineralogical composition and average particle size. The fractions retained on each sieve, which ranged 180 – 500 …

Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually …

view more6 · I recently read that sodium thiosulfate can be used for gold and silver leaching in much the same way as cyanide, but with no worries about toxicity. This intrigues me: aqua regia is a pain to work with, and cyanide is too toxic for an amateur, but thiosulfate is already one of my favorite reagents - cheap, nontoxic, and has so many uses. I thought I'd ask …
