The Two Important Ores Of Lead


Lead - The primary ore mineral for lead is its sulfide - galena. Some minor production from the past has come from secondary lead minerals - cerussite and anglesite. Lithium - The former primary ore minerals were pegmatite deposits of spodumene, lepidolite, and petalite, amblygonite. Currently the major U. S. production is from lithium carbonate brines.

Galena - Wikipedia

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

Ore - Wikipedia

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost ...
