Hello friends: I'm a slag leaching gold cyanide containing much antimony. The analysis of the solution give 0.265 g / lt. 3grs/lt gold and antimony. Antimony interferes with gold precipitation of zinc powder or the use of activated carbon. I think you could help me by suggesting a way to precipitate the antimony before precipitating gold.

One of antimony's primary uses (accounting for about 50% of consumption) is in the form of antimony xide in flame retardants for plastics, textiles and other materials. But the use of antimony as a clarifying agent in photovoltaic (PV) glass in China is expected to surpass its use in flame-retardants in the very near future.

The froth flotation process can not only enrich maximum gold into the sulphide mineral concentrate, but also discard the tailings, so the processing cost is low. Besides,froth flotation method can also be used to polymetallic gold mining, such as gold-copper, gold-lead, gold-antimony, gold-copper-lead-zinc-sulfur ores.

The reason for this is that coarse gold, being easily amalgamable, is almost all caught on the inside plates, while fine gold, even if amalgamated; in the battery, forms a more fluid amalgam which passes through the screens and is caught outside. Coarse gold forms a richer and stiffer amalgam than fine gold, for the reason already given on p. 15.
