Alternately, you can smelt it as normal (roast sulfides to oxides, reduce with carbon and slag in a blast furnace) and extract the silver metal two ways: chemically, with zinc, or electrolytically. Chemically is basically as above except starting from metal rather than roasted ore. With zinc, you melt 99%...

For precious metals like gold, silver, platinum, and palladium, we start by melting your material in one of our induction furnaces while also adding the appropriate custom blended flux to remove impurities. Then we thoroughly mix the molten material to insure a uniform sample, lift out the crucible, and pour the liquid metal into a mold.

Platinum Refining Process is described below. Platinum refineries provide an economical and environmentally friendly precious metal recovery service. We buy platinum scrap and separate the pure platinum from other precious metals and waste materials. Platinum scrap such as platinum coins, palladium PD and platinum wire is weighed and then smelted.
