Bosite low-grade copper sulfide ore leaching process, leaching copper oxide ore, new chalcopyrite collector
The separation of copper ore is mainly flotation, and gravity separation or combined process of dressing and smelting can also be used.
Sorting of copper sulfide ore: Different processes are adopted according to the properties of the ore:
To process extremely fine copper ore embedded with copper minerals, choose stage grinding, stage flotation or multi-stage grinding , centralized flotation process.
To process high-sulfur copper-zinc ores, use two-stage grinding and other flotation processes to select copper & zinc mixed concentrates. The tailings are added with copper flotation to obtain zinc & sulfur mixed concentrates, and then separately Separate to obtain copper concentrate, zinc concentrate and sulfur concentrate
To process copper ore containing more pyrite, adopt a one-stage grinding, copper & sulfur mixed flotation process, mix the coarse concentrate and then grind it Then separate copper and sulfur
To process copper ore containing low-grade molybdenum, a one-stage grinding and mixed flotation process is generally used to select copper & molybdenum mixed concentrate. The mixed concentrate is then ground again to separate copper and molybdenum.
To process ores that contain a lot of mineral mud and have large differences in sediment floatability, a sediment separation process is used.
Sorting of mixed copper ores:
The acid leaching & precipitation & flotation process is suitable for processing oxidized ores with higher copper content. The process is: spray the ore pile, and replace the leachate with scrap steel , concentrated and dried to obtain precipitated copper
The isolation method (there are one-stage isolation and two-stage isolation) is used to treat refractory copper oxide ores with high combined copper content
Leaching & extraction & electrowinning methods are suitable for treatment Low-grade copper oxide ores and mixed ores
The bacterial leaching method is suitable for treating low-grade copper ore resources with complex copper mineral occurrence conditions that cannot be reasonably utilized by the mining and dressing industry, such as copper-containing waste rocks.
Typical copper concentrator Dexing Copper Mine Concentrator: Located in Dexing County, Jiangxi Province, China, Dexing Copper Mine is the largest porphyry copper deposit in China. The ore has veinlet type and infectivity. The metal minerals in the ore are mainly pyrite, chalcopyrite and molybdenite, followed by chalcocite, bornite and a small amount of azurite, tellurium gold and silver ore, silver gold ore and natural gold. Gangue minerals mainly include sericite, quartz, chlorite, etc. The production scale of this mineral processing plant has reached 10,000/year, and it is China's first large-scale copper mining and processing complex. The process flow of the first and second concentrators is roughly the same: crushing adopts a three-stage closed-circuit process and grinding adopts self-grinding & ball milling & fine crushing open-circuit self-grinding process. The graded overflow particle size is .%. Copper, molybdenum and sulfur mixed flotation are used. , after the coarse concentrate is reground, copper & sulfur separation is carried out. Finally, copper concentrate, sulfur concentrate and molybdenum concentrate are obtained.
