The methods employed in dressing the tin ore up to the required percentage of purity depend mainly on the type of ore crushed. These may be briefly divided into two distinct classesviz., a free milling ore andplex milling ore. In the former the ore is practically free frommon metallic sulphides, such as. pyrites, mispickel, blende, galena, and a clean
Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade e.g., 3 to 10 parts per million that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then

The ore is enriched using a process called froth flotation. Unwanted material called gangue sinks to the bottom and is removed. Roasting This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine. Smelting with fluxes A flux is a substance which is added to the
