Lead Galena Materials. Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver.
Galena lead is a precious metal derived from the mineral galena. Galena, commonly known as lead sulfide, is a significant lead source. Mining, crushing, grinding, and smelting are all steps in the extraction of lead from galena. Galena lead has several applications in a wide range of industries.

The recovery process of metal lead and zinc was systematically investigated. The addition of galena-sphalerite to the electrolyte solution proved that more than 71.55% of the lead was recovered with less than 2.20% zinc was dissolved. The ClO − has been proven to be a mineral leaching catalyst. In addition, the reaction mechanism …
Lead occurs as galena (PbS), cerisite (PbCO3 ), and anglesite (PbSO 4). Galena is the most common. Lead ores are usually roasted and then reduced in a blast furnace with coke.
