Copper ore crushing & grinding
Copper ore a valuable mineral source for all countries. Copper ore is an ore which can produce copper metal by crushing in ore crushing plant, grinding in ball mill and smelting in a furnace along with a piece of tin ore. SBM is a proessional manufacturer of copper ore grinding equipment and crushing equipment.
Copper ore mining
Most copper ore is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include: Chuquicamata in Chile, Bingham Canyon Mine in Utah and El Chino Mine in New Mexico, US. The average abundance of copper found within crustal rocks is approximately 68 ppm by mass, and 22 ppm by atoms. In 2005, Chile was the top mine producer of copper with at least one-third world share followed by the USA, Indonesia and Peru, reports the British Geological Survey.
Copper ore crushing and grinding process
First the copper ore is blasted, the copper ore stone will be loaded by a heavy duty truck, then be transported into the primary crusher which reduces the ores to 8 inches or smaller. Screens size and distribute the classified ore to a series of conveyors, like those above, for transportation to the mill for further processing.
After crushing process, the copper ore is send to ball mill for grinding. Inside the ball mill, the crushed copper ore will grind the ore to about 0.2 mm with 3-inch steel balls. This copper ore slurry is finally pumped to the flotation deck. This copper ore slurry is finally pumped to the flotation deck with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.
Copper ore crushing plant and grinding plant
In the primary crusher, SBM jaw crusher is the most popular machine, which features easy maintenance, low cost, high ratio, etc. In secondary crushing process and tertiary crushing process, SBM has improved our CS cone crushers' and hydraulic cone crushers' capacity and end crushing products. The total energy consumption is reduced considerably. Comparing the operation efficiency of CS cone crusher and hydraulic cone crusher, we find CS cone crusher achieved better results in tertiary crushing. And if installing the same number of secondary and tertiary crushers, a part of operation is transmitted from tertiary to secondary crushers where the liner wear is three times less, which significantly influences on the cost reduction in the crushing process.
Crushed copper ore is then loaded on to a conveyor belt which takes it to the storage bin. In the storage bin, ball mills and other grinding machine grind the ore until it is a fine powder.
