Black sand may be generally defined as a constituent of “alluvial” gravel consisting mainly of fine particulate grains of heavy dark colored minerals and rocks These alluvial gravels chiefly concentrated by wave current or surface action may also contain “eluvial” material that includes black sand The eluvium which results from decomposition or disintegration in place of an ore 7/4/ 32 If your black sand does not contain silver only gold will react and will later be precipitated Of course you can act on it before with an acid or acid/peroxide if you re really bothered However this will convert thiosulphate to sulphur Easier to separate gold at the end

Fundamental aspects of thiosulfate leaching of silver Thiosulphate leaching of silver from an arsenical

Thiosulfate is a promising alternative for leaching silver sulfide ores such as those at the epithermal Yanacocha deposit These ores suffer from low silver recovery high mercury extraction and environmental challenges when treated with conventional cyanide In this study cupric ammonia ferric ethylenediaminetetraacetic acid EDTA ferric oxalate and ferric citrate are tested with None of the thiosulfate alternatives were able to recover as much silver as cyanide leaching likely due to the presence of other silver minerals which may not be amenable to thiosulfate leaching
