Jan 01, 2016nbsp018332Where the ore is high in silver, typically with a recoverable silver content of more than 10 gt 0.3 ozton of ore, Merrill-Crowe zinc precipitation is used instead of carbon adsorption. In this process the solution is clarified and de-aerated, then contacted with zinc dust to precipitate metallic gold and silver.
This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt mixes is a useful technique to small-scale operators experimenting with smelting techniques on gold-silver ores. It could also be used with small lots of sulfide concentrates.
process is usually able to recover 85 to 95 percent of the copper in the ore. The dried concentrate contains approximately 20 -30 percent copper by mass, 30 per cent iron, 30 per cent sulphur, with the remainder including small amounts of gold, silver, and unwanted elements such as arsenic and mercury.
