Document Summary
Calcination and roasting- learn about this you missed the intro lolz. Metal is in a workable form converted to oxide. Removing charge and converting it to neutral metal atom. Reduction method where the metal oxide is converted to metal. Ore is melted with a reducing agent and process involves calcination, roasting and reduction (smelting) Or we can take the metal oxide and smelt it at a smelting point with the reduction. Depends on the method of reduction used which determines the personality of the metal. Electrolytic regining: very high purity attained, very convenient, electrolysis- anode, cathode and electrode, blocks of impure metal (anode), pure metal (cathode) and solution (electrolyte) 100 purity= thermal method impure metal is heated with co: form a compound with the pure substance and co, the rest of the stuff will stay behind, after decomposition, there will be pure metal as a product. Raw iron is very brittle, rusts easily.
