Zinc | Geoscience Australia
Zinc has never been found naturally in its pure form. It can be alloyed (mixed) with a number of other metals. Zinc is brittle at ordinary temperatures but is malleable and ductile (can be beaten and drawn into a wire) when heated to 1000°C. Zinc has a relatively low melting point and is a good electrical conductor.

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.
