Mineral Ore Dressing Process. Mineral ore that suitable for deep processing are gold ore, copper ore, magnetite, manganese ore, lead zinc deposit, etc. For most mineral mine, the processing capacity usually is not very large, the common crushing and beneficiation capacity are about 1 ton to 100 ton, so we can call them as small scale mineral ore process.
In general, ore dressing plant may use primary, secondary and tertiary crushing processes for crushing iron ore. Jaw crusher is usually used for primary crushing; cone crusher is used for secondary and tertiary crushing. Through primary crushing, and then by secondary and tertiary crushing, ore will be crushed to the suitable size for feeding ball mill.
The ore lumps from the mines have the lump size of 10 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
Crushing in Mineral Processing. In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them ...
