lead processing - lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral ...

Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative items of all types. Likewise, it has been used for silverware.

Lead ores containing silver are extracted by cupellation, a process developed by the Chaldeans as early as 2,500 B.C. Today, the cupellation process involves heating crushed ore on a porous bed of bone ash until it melts. The lead and other impurities are absorbed into the bone ash, and the molten silver is drawn off.
