Galena an overview ScienceDirect Topics
Galena’s black, shiny particles have Because of the thermodynamic equilibria of these reactions, it is not possible to produce in one stage both a low-sulfur lead bullion and a low-lead slag. Therefore two stages—oxidation followed by reduction—are needed. A high-lead slag from the first stage is reduced by coal in the second stage. The Swedish Kaldo or top-blown rotary converter

Lead Wikipedia
Lead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena is a principal ore of lead which often bears silver. Interest in silver helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial
Extracting Lead Materials from Ore
Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjunction with other metals such as silver and zinc.

The Earliest Lead Object in the Levant
02.12.2015· Lead occurs in nature mainly as galena (lead sulphide) and cerussite (lead carbonate). Prior to the Romans, who used metallic lead extensively, objects made of lead were relatively scarce and small. Because of its high specific weight, lead was mainly used by fishermen to hold down their nets, or as filling material in bronze commercial weights. Otherwise, lead was sometimes added to copper
