8/6/2013· The metal lead (Pb) is produced from its oxide (PbO) by a two step process which involves roasting the ore (PbS, galena) and the subsequent reduction of the lead oxide (PbO) thus formed PbS + 3/2O2 PbO + SO2 PbO + CO Pb + CO2 (a) What mass of PbO is obtained from 1 tonne of the ore? (b) What volume of SO2 is produced in processing this amount of ore?

Processes extraction, mining, smelting, refining

First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

Extracting metals How are metals with different

Metals can be arranged in order of reactivity by observing their reactions with water, acid and displacement reactions with other metal compounds. This determines how it is extracted from its ore.

extraction of metals introduction

The treated ore is then put in a large bath of water containing a foaming agent (a soap or detergent of some kind), and air is blown through the mixture to make a lot of bubbles. Because they are water-repellent, the coated particles of the metal compound tend to be picked up by the air bubbles, float to the top of the bath, and are allowed to flow out over the sides.

Mercury processing Extraction and refining Britannica

The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air, oxygen combines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point. The gases are then passed through a series of U-shaped tubes to condense the mercury vapour to the liquid phase.

5a. The Extraction of Lead. Because its position in the reactivity series of metals, lead can be extracted using carbon (coke) in a smelting furnace.Because lead is below carbon, that is less reactive than carbon, lead can be displaced by carbon from lead oxides or lead sulfides in a sort of displacement reaction. The principal ore of lead is galena, chemical formula PbS lead sulphide (lead(II

Concentration of Ores: Hydraulic Washing, Froth Flotation

Leaching is a chemical process of concentration of ore. Here the ore dissolves in a chemical solution. The minerals will react and dissolve leaving behind the impurities only which filter out. And then the metal will be obtained from the chemical solution. Let us now take a look at an example of how we obtain Aluminium by leaching. Bayer Process
