Copper metal is one of the earliest metals used by human beings in history. It has excellent performance and widely used in power electronics, light industry, machinery, construction, transportation and other fields. With the continuous development of the economy, the demand for the copper metal is also growing. In order to meet the increasing demand, how to obtain more copper production from the limited copper resources and improve the efficiency of   copper extraction   has aroused people’s attention. Selecting the suitable ore dressing process is one of the necessary conditions for the high-efficient operation of the mineral processing plant. In order to obtain high yield copper and improve the efficiency of mineral processing, we need to choose the ideal copper extraction process. So how much do you know about the copper extraction process? One. Classification of copper ore Due to the different types of copper ore, the nature of the copper ore is different, so the c...

Most   copper dressing plants   are always nagged by the low copper recovery rate. In the usual mineral processing plant, the recovery rate and quality cannot be satisfied at the same time. Throughout the concentrator’s operations, some copper impurities cannot be completely removed, nor can they be completely dissociated. If this part of the ore is recovered, the grade of the copper concentrate will be reduced. However, if it is thrown away, copper ore recovery rate will be reduced. If dressing plants not only want a higher recovery rate but a higher quality, they must choose right copper processing solution. A good example of getting a higher recovery copper rate is Jiangxi Dexing   copper dressing plant . The copper in Jiangxi is characterized by large-scale reserves, the low grade of raw ore and good optional. From the process to equipment selection, this plant is called as the most comprehensive and representative of the processing plant in China currently. Th...

The selection of equipment is closely related to ore property in the mineral processing plant. However, due to individual differences, there are significant differences in various equipment. Because the ore is different in the whole plant, different equipment is needed to process the ore. Therefore, mine owner must research copper ore property and type before determining copper ore dressing equipment . Taking Jingxi Dexing copper ore dressing project as an example, the deposit type of this project was porphyry copper, which can be divided into altered phyllite and altered granodiorite two types according to different ore properties, and it can be divided into veinlet and disseminated types according to different structures. There was a small amount of oxidized ore and mixed ore in the upper and periphery of the ore body. The raw ore include 0.5% copper, 2%sulfur, 0.01%molybdenum, gold content was up to 0.235g/t. Mineral compositions were much simple, useful minerals were mainly pyrit...

The common copper sulfide minerals mainly include chalcocite, covellite, bornite, copper pyrites and tennantite, and their inherent floatability decrease in turn. Copper sulfide ore has better floatability than sphalerite, pyrite and another sulphide, so it is more likely to float from the pulp by adsorpting collecting agent. Therefore,   flotation process   is the main beneficiation method for copper sulfide ore. The common collecting agent used for copper sulfide ore flotation process is xanthate collectors, followed by aerofloat and its esters. Actually, The collecting effect is much better if aerofloat esters mix with other agents. The xanthate collectors used in copper sulphide ore flotation process are sodium ethylxanthate, SIPX and Sodium n-butylxanthate, etc. The common aerofloat includes cresol aerofloat, ammonium dibutyl dithiophosphate, aerofloat 208, aerofloat 238, aerofloat 242, etc. Many research shows that the mixed-use multi-collectors have a better flot...

There are rare native   copper   deposits but abundant copper tailings in China. According to incomplete statistics, hundreds of millions of tons of copper tailings are discharged every year in China, which are increasing year by year. Copper tailings include little copper, silver, zinc, lead ore, but a large number of silica-aluminate tailings, such as calcite, plagioclase and diopside. Generally, complex copper ore composition and outdated mineral processing technology and equipment lead to the different copper content in copper tailings. The large number of copper tailings that are not fully utilized not only occupy areas, but also cause serious environmental pollution. Therefore, it is necessary for economic benefit and environmental protection to study the secondary utilization of copper tailings and develop circular economy. The characteristics of copper tailings composition in China are the high grade of copper, fine grain size, various types and complicated comp...

In copper beneficiation solutions, copper mining process equipment price is related to its type, specification, and minerals to be processed. Among these factors, the type of mineral is the key to choose the most suitable equipment. To make sure copper mining process equipment type and specification, the quality and type of copper should be studied. Taking the example of copper in Dexing, Jiangxi, it is a kind of porphyry copper deposit. And according to different mineral quality and containing properties, it is divided into two types, altered phyllite and altered granodiorite. It also can be divided into the thin vein and disseminated structure, according to various structures. There is much-oxidized ore and mixed ore in the upper and surrounding of ore. The content of copper in raw mineral is 0.5%, sulfur 2%, molybdenum 0.01%, gold 0.235g/t. The composition of ore is simple, and the mainly useful minerals are pyrite, chalcopyrite, and chalcocite. Then there are chalcocite, bornite...

Copper and molybdenum are accompanying minerals. Almost over 20 percent molybdenum is recovered from copper and molybdenum. Copper and molybdenum ore, which are mainly copper ore, is existed as porphyry copper with high recovery value and low grade of molybdenum (0.01~0.1%). Copper in copper and molybdenum is existed mainly as CuFeS2, Cu2S, while molybdenum is existed as MoS2. Copper and molybdenum include preferential flotation , part combined flotation and combined flotation. Preferential flotation contains two processes: one is concentrate molybdenum first, while another is concentrate copper first. There are some shortcomings of preferential flotation: copper and molybdenum is hard to reactivated, flotation process is complex, flotation index is worse, and process cost is high. Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molyb...

With the continuous copper ore mining, there is fewer and fewer high-grade copper ore, and copper ore block size is getting smaller and more complex. Ordinary flotation process seems not available for those ore. At this time, "poor, fine, miscellaneous" copper ore dressing process - the biological leaching process was born. The following is a brief introduction of biological leaching of copper production line. Common microbe mineral processing technology are heap leaching and leaching. Heap leaching means to heap mined ore, and then use microbe leaching solution. Due to its production cost is low and less pollution, it has been widely used. Situ leaching is to use a chemical solvent or microbial leaching solution to inject underground mines copper and dissolve copper and other valuable metals, then collect the dissolved rich liquid. This kind of processing method is the combination of mining and mineral processing, and there is no need to ship the ore out the ground whic...

Similar to other mineral processing solutions, there are many factors that affect the   copper mining processing . Only recognizing these factors in copper mining processing designing can we improve the economic benefits of the copper mining plant. Particle size is an important parameter of influencing the result of copper mining processing. In the copper ore mining processing designing, the fineness of the copper ore is determined by the   copper mining equipment . At the same time, the over fine particle size will lead to the increase in the ore grinding energy consumption and marginalization. Those all affect the copper mining flotation indexes. In selecting copper mining reagent, the copper ore with coarse and fine sizes should adopt the proper flotation reagent. The reagent system refers to the flotation reagent kinds, dosage, the adding order, location, way(one time or separately add), the compound method and the working time. It is an important operating index in...
