EXTRACTION OF LEAD FROM GALENA CONCENTRATES

EXTRACTION OF LEAD FROM GALENA CONCENTRATES

Extracting Lead Materials from Ore Lead is a dense soft lowmelting metal Lead is the densest common metal except for gold and this quality makes it effective in sound barriers and as a shield against XraysLead resists corrosion by water so it makes a longlasting roofing material Only about half of the lead materials used today are produced from mining the rest is obtained from Feb 20 2017 The majority of the deposits are mixtures of minerals hence lead ore is usually obtained as a byproduct of other metal mining such as zinc silver or copper In fact lead ore is a main source of silver and contributes substantially towards the worlds total output The most common lead ore is galena PbS which contains 866 lead

May 07 2013 The microchemical results provide the evidence that the ancient metallurgists knew and successfully controlled in an empirical way the silver extraction process by thermally treating the argentiferous galena PbS by smelting Agbearing lead ores and then by carefully and selectively oxidising the latter by adopting tailored parameters in such a way to form at about 1000 C liquid The extraction of lead from a galena concentrate in nitric acid solutions with additional hydrogen peroxide was studied taking stirring speed temperature hydrogen peroxide and nitric acid
