extraction of tin from its ores

Types of Extraction | S-cool, the revision website

When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound. Electrolysis Electrolysis is the most powerful extraction method.

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Extraction of metal from the ore cassiterite involves: - Vedantu

The natural mineral ore of the metal tin (Sn) is cassiterite; it is an oxide ore of tin with the formula Sn O 2. To remove the oxygen and to get a pure metal in the extraction process, the ore is heated to high temperatures of about 250 0 o F. This process of heating an ore in the absence of oxygen is known as smelting.
