Description
Heavy soft grey solid material.
The natural pure lead is rare. Today, the lead mainly smelt and extract together with zinc, silver and copper and other metals. The most important lead ore is the galena PbS, which the lead reaches 86.6%. Other common lead-containing minerals are PbCO3 and PbSO4. And the world's largest lead producing country is China, the United States, Australia, Russia and Canada. Today, more than half of the lead is from recycled.
Most ores contain much less than 10% lead, and ores containing as small as 3% lead may be economically exploited. Ores are crushed and concentrated by froth flotation ordinarily to 70% or more. When lead is exploited to the floor, it should certainly be crushed or grinded for its additional application.
