    Extraction of Tin Tin: Atomic Number: 50 Electronic configuration: [Kr]4d 10 5s 2 5p 2) Tin is extracted from cassiterite ore. The extraction involves the following steps: Concentration: The crushed and powdered ore is washed with running water, which removes lighter siliceous matter. Wolframite is removed by electromagnetic separator. Roasting: S and As are removed as their volatile oxides

    The methods chiefly used for the extraction of lead and tin from their ores are respectively self reduction and carbon reduction. Self reduction for lead is as follows. 2 P b S + 3 O 2 → 2 P b O + 2 S O 2 ↑ P b S + 2 O 2 → P b S O 4 2 P b O + P b S → 3 P b + S O 2 ↑ P b S O 4 + P b S → 2 P b + 2 S O 2 ↑ Carbon reduction for tin is as follows.

  • Leaching Mining Fundamentals

    This method is most effective for the extraction of metals from difficult ores, and is one of the most tried and tested methods. The pre-processing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore. After pre-processing, the ore is leached with acid of alkali solutions to extract the metal. Heap

  • Bismuth: extraction-Metalpedia

    The extraction from ores in which the bismuth is present in the metallic condition may be accomplished by a simple liquation, or melting, in which the temperature is just sufficient to melt the bismuth, or by a complete fusion of the ore. The first process never extracts all the bismuth, as much as one third being retained in the matte or speiss.
