Extraction Lead is mainly extracted from the sulphide ore galena. Galena contains lead sulphide and small quantities of silver. 1. Concentration The ore is concentrated by froth floatation process. 2. Smelting in a Reverberatory furnace The concentrated ore is roasted in a reverberatory furnace at a moderate temperature.
This entails mixing the galena powder with sodium carbonate and salt under an oxygen lance in a crucible. This way any sulfur dioxide is absorbed by the carbonate. This is a patented known process and would be much easier and safer than regular smelting. I think at around 900 C I have a hobby furnace capable of upto 1200 C
