Silver Refinery & Lead Alloys

Silver Refinery

Lead Alloys

Slimes collected on the corroded anodes are treated in a series of three furnaces to recover silver and gold from the other heavy metals. Other processes are used to recover marketable bismuth, arsenic, and antimony and to recycle unrecovered lead to the Kivcet Furnace. Some of these metals are also used to make various alloys with the purified lead, for specific customers.

The photograph at below shows 1000-oz silver bars being poured in the Silver Refinery.
