3. Lead-bearing Silver ores: These are silver ores containing 4 percent or more of lead. The silver comes mainly from the lead-silver ores of Coeur d'Alene, Idaho, Utah (chiefly Park City and Tintic), Colorado (Leadville and Aspen). Most of the output is obtained by the de-silverization of lead bullion using molten zinc.

PARTING: Separate Gold and Silver by Melting
The processes of parting may be tabulated as follows: Cementation. Melting with sulphide of antimony. Melting with sulphur, and precipitation of the gold from the regulus by silver, iron, or litharge. Parting by nitric acid. Parting by sulphuric acid, sometimes called "refining.". A combination of these last two methods.
