US5290338A - Antimony separation process - .

An antimony recovery process is disclosed in which antimony-containing material is leached in a solvent including elemental sulfur and a caustic to preferentially leach antimony. The antimony-containing leach liquor from the leaching step is separated from the insoluble residue by filtration, and the antimony compounds in the separated leach liquor are crystallized to separate the antimony ...

antimony, with a small amount of iron as an impurity. Having proved this, we still had to explain how the copper happened to be so coated. Antimony could not have been deposited on the objects during the cleaning because we used nothing but chemically pure alkalies and acids which contained no trace of antimony. Nor do we believe that antimony ...

Gold parting - Wikipedia

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to .
