  Extraction of Lead

   · Flotation • The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfurbearing portions of the ore, which also contains the valuable metal. • First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell. The ground ore and water mixture is ...

  Brief Introduction of Dithiophosphate | CNFREE

   · It is an effective collector for copper, lead and silver sulfide ore and activated zinc sulfide ore. It is commonly used in the priority flotation separation of lead ore and zinc ore. In the alkaline medium, the dithiophosphate 25 has weak collecting effect to pyrite and other sulfide minerals, and has certain selectivity. However, in neutral or acidic medium, dithiophosphate 25 is the strong ...

  Galena

  Galena is the main ore of lead, used since ancient times, since lead can be smelted from galena in an ordinary wood fire. Galena typically is found in hydrothermal veins in association with sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and is also found in association with sphalerite in lowtemperature leadzinc deposits within ...

  Lead Metal Processing Technology

  Primary Lead Processing. Primary Lead production begins with sintering. Concentrated Lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. The mixture is blasted with hot air to burn off the Sulphur and sent to the smelter. Lead Melting Technology

  Lead Ore / Lead Concentrate Smelting, Manufacturing ...

  In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then treated using extractive metallurgy. The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate. The concentrate, which can range from 50% to 60% Lead, is dried and then treated using ...

   · Suppose we conducted a processing circuit for a lead ore as follow: After grinding we screen the ore into two fractions +150 microns and 150microns ( Separation1) +150 microns goes to a table ( Separation2)150 microns goes to the flotation (Separation3) then we got two concentrates (cS2,cS3)and two tails (tS2,tS3). Now we want to calculate lead grade and recovery in every product. .
