The working condition of a processing plant is constant and choosing the best processing solutions is related to the ore nature. Taking Jiangxi Dexing copper mineral processing as an example. Firstly, look at the copper mine process, the porphyry coppers is surrounding rock, mainly acidic porphyry, and metal minerals of this type of deposit are mainly chalcopyrite. According to copper ore process, copper ore process also adopts the best process to develop according to the ore properties.
The copper mine process is three stages with closed-circuit and washing (with spiral classifier shaker) process, now the amount of mud becomes less, and it changed to three closed-circuit process, this copper mine process can be finally crushing the ore to less than 15mm. The equipment used here including lattice screen, vibration screen, jaw crusher, cone crusher, classifier and other equipment. The size distribution of pyrite is 0.003~0.4mm, and most is grain. When the particle size reaches 0.14mm, the degree of dissociation of single body can reach more than 80%. However, due to the need of fine grinding, the ore is not uniform, only fine grinding can achieve better selection index.
