Ores found on the earth contains many impurities like sand, rocks, and grit in them, which are collectively known as "Gangue".The concentration of ore is a method of removing gangue particles or other impurities in order to purify the ore. This process is also called Ore-dressing and benefaction.It is a very crucial step to obtain a pure metal from …
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
Before the beneficiation of copper ores, crushing and grindingare required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. …
The jaw crusher is mainly used for medium-sized crushing of ore and bulk materials. It can crush materials with a compressive strength of up to 320Mpa. It can be divided into two …
