Ore
Ore is a volume of rock containing components or minerals in a mode of occurrence that renders it valuable for mining. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. The common ores are Bauxite, Iron ore, Manganese, Copper. An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element.
Ore crusher
There are several types of crushers to be choosed as ore crusher. Jaw crusher usually is primary crusher for ore primary crushing. Impact crusher is also can be used in ore crushing process. Because ore is the strict in shape, so we also need vsi crusher, it can crush stones into cubic pieces. Then text step is screening process. According to the requirements of size, choose the right screening machine to screen out the eligible ore.
The ore crushing process:
Generally, the complete ore crushing plant consists of jaw crusher, ball mill, classifier, magnetic separator, flotation machines, thickener, dryers and other major equipment, such as vibrating feeder, bucket elevator and belt conveyor. This production line feature with high efficiency, low energy, high capacity, economical and so on.
The primary crusher reduces ore from the trucks to 8-inches or less. That material goes to the primary stock pile directly that you see crushed rock falling onto in your image. Two conveyors (out of view to the right in your image) pull this material directly into each SAG mill where it is combined with water and mill balls (as needed).
Big raw ores are feed to the jaw crusher evenly and gradually by vibrating feeder for primary crushing. After primary crushing, the material will be transferred to other crushers by belt conveyor for secondary crushing, then the crushed materials will be transferred to vibrating screen for separating. Final, the materials will be transferred into the ball mill evenly for ore grinding.
The ore milling process:
Following grinding in the ball mill, the material is returned via the sump to the secondary hydrocyclone for resizing. The trash screen removes wood from the old workings that may have found its way into the processing circuit. The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation the size required for the cyanide to be able to 'see' the gold in the leaching process.
The remaining slurry passes through a pre-leach thickener, to remove some of the water. The recovered water is reused in the grinding circuit while the thickened slurry moves into the leaching circuit.
