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...

As one of the commonly used mineral processing equipment , the quantity and proportion of steel balls in ball mill barrel not only affect the grinding efficiency and production capacity of ball mill, but also affect the ball mill’s service life. In the operation process, grinding efficiency of ball mill generally depends on the sum of the work done by each steel ball (the number of steel ball impact and the impact force produced by steel ball). Therefore, to give full play to the crushing efficiency of each steel ball, it is necessary to ensure that steel balls moving along different trajectories do not collide as much as possible. When the steel balls in ball mill barrel are too much, the steel balls will overlap with each other, so that part of the steel balls cannot rise to the required height and then fall down, unable to give full play to crushing ability. At the same time, it also increases the kinetic energy consumption and shortens the service life of the ball mill. When the ...

Sludge thickener can play a very important role in the process of sludge treatment. This paper will introduce the problem of flocculant when sludge thickener processes sludge. There are several ways to add flocculant to the pulp in the sludge thickener. Different methods mean different effects. The method of multi-add flocculant solution is to distribute polymer effectively, so as to shorten the mixing time between flocculant and slurry. The mixed systems are as follows: first, adopting flocculant solution sprayer or tank with flocculating solution nozzle and damper. Second, make a very short stirring before sending to sludge thickener. In this way, flocculant solution can disperse well in the slime water, but the standing time in the reaction area is not shorter than polymer absorption. Therefore, Flocculation group cannot be hindered in terms of formation and growth. Synthetic flocculant is the most common flocculant that used to treat coal industrial wastewater. This flocculant i...

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...

It is unavoidable for crusher to occur blockage in crushing production line, which not only reduces the crushing capacity, influence of finial granularity, but also affects the production efficiency, even cause equipment damage. So, how to prevent and solve the problem of crusher blockage problem? The main reason why crusher occurs blockage is material properties. Because the material contains much moisture, the ore material has a certain viscosity. When the ore material is sent to the crusher for crushing into small pieces, the ore material will stick together, and block between two pieces of jaw plates of crushing cavity, then causes material blockage phenomenon; Or the ore material is mixed with a large amount of sticky soil, so that the material is blocked in the crushing cavity. So, how to avoid this blockage phenomenon as soon as possible? Before sending the material to the crusher, we need to screen and dehydrate the material, which can reduce the moisture and viscosity of th...

The slurry concentration refers to the content of the solid material in the slurry, usually represented by wg which is used to define the ratio of liquid to solid or solid mass fraction. The slurry concentration is one of the most important factors which affect mining hematite ore. It will affect the charging degree of hematite ore slurry, the residence time in of hematite ore slurry in the flotation cell , reagent system and the adhesion process of bubble-particle. The article is going to introduce the effect of slurry concentration on mining hematite ore . (1) The inflatable performance of flotation cell changes with the hematite ore slurry concentration. Whether the slurry is too thick or too thin will make the inflation situation worse, thus affecting the hematite ore flotation recovery rate and flotation time. (2) Under the same dosage, if the slurry density increases, the reagent concentration also will increases, which will be conducive to mining hematite ore so as to reduce t...

Although gold in nature exists in the form of simple substance, gold usually has the complex associated relation with other minerals in the raw ore. The conventional physical separation sometimes cannot be competent for grading the gold ore because of mineral the particle sizes, the associated relation and other reasons. It turns out to be the common beneficiation process of the gold dressing plants according to a hydrophobic difference in the mineral surface. Generally, there are many influential factors in the gold flotation process , like particle size, flotation reagents, pulp density, the flotation time, stirring intensity, inflating volume, pulp temperature, and etc. If we want to get a better flotation effect, we must keep the best value for each parameter. 1. Particle size The milling fineness in the gold flotation process is determined by the gold dissemination size. Oversize and undersize will both affect the final flotation effect. Oversize on the one hand may not achieve ...
