As the expand of graphite application field, the industry has a higher and higher requirement for the graphite, which encourages the graphite graphite mining to absorb the traditional  graphite beneficiation process  and keep continuous innovation at the same time. At present, the graphite beneficiation processes are mainly gravity separation process, froth flotation process, electric separation process and the combination process. And froth flotation process is the main  graphite mining  process. Generally, 90%-97% grade of graphite concentrate can be obtained after the graphite flotation process. For the different graphite ore properties, the graphite beneficiation processes are also different. 1.   Massive crystalline graphite mining For the massive crystalline graphite, because of the high-grade carbon in itself, finer particle sizes and the smaller reserves, we can adopt the traditional crushing and hand picking technology to take advantage of it. It has the advantages of

The common fluorite beneficiation processes include gravity separation and fluorite flotation process.  Gravity separation  process can be used for coarse-grained fluorite ore. And  fluorite flotation  process can be used to process fluorite ore that is associated with impure minerals and the granule of value mineral is so tiny. Fluorite is often associated with quartz, barite, calcite, sulphide and other minerals. Different fluorite flotation processes should be adopted according to different ore properties. 1.   Crushing and Screening Due to different properties of fluorite ore in different areas,  three stage a closed-circuit or three opening crushing process can be used in the crushing stage of fluorite beneficiation process. The  crushing machine  used in fluorite beneficiation process is shown below. Name Application Particle Size(mm) Jaw Crusher Coarse Crushing <1250 Standard Cone Crusher Secondary Crushing <350 Short-head Cone Crusher F

According to the type of deposit, feldspar can be divided into pegmatite feldspar, white granite feldspar, granite feldspar and feldspar placer. Because of the different deposits and ore characteristics, the feldspar mining process is quite different with each other. The common feldspar mining processes include hand sorting, desliming, magnetic separation,  gravity separation , flotation and combined process, which can separate quartz, iron, mica and other minerals. 1. Pegmatite feldspar mining process Commonly, the pegmatite feldspar has good quality feldspar ores, which has simple mineral constitute. So, the pegmatite feldspar mining process is rather simple than other minerals, including selecting, crushing, grinding, and strong magnetic separation. • Selecting: hand sorting or color sorting, which can separate big chucks. • Crushing: rough crushing and fine crushing. • Grinding: continuous grinding operation is carried out by using the gravel mill or rod mill lined with

Silver ore is a very important metal material in the field of modern industry, with good electrical conductivity, thermal conductivity, corrosion resistance, organic acid resistance, plasticity and other high-quality characteristics, which is widely used in the chemical industry, metallurgy, environmental protection and other industrial fields. As to the  extraction of silver , the flotation method is generally used for the extraction of independent Ag deposit, while the combined process of single flotation method and floatation-gravity separation method and floatation-cyanidation method are used for the extraction of the common and associated silver. But the flotation method is still the most important silver extraction process. Extraction of silver-flotation process Extraction of silver usually needs crushing, grinding and extraction three stages. The main equipment used in the extraction of silver includes jaw crusher, ball mill, spiral classifier, flotation machine, thickener,

Vibrating screen, as one of the common  screening equipment , mainly depends on its vibration characteristics to complete the classification, dehydration and desilting operations, which is widely used in the screening operation of mineral processing plant. In the production practice, because the complex working environment, continuous work for a long time and heavy load, the vibrating screen is inevitably damaged or even break sown. In order to ensure the normal screening operation of the concentrator, we need to carry out daily maintenance and overhaul for the vibrating screen, and take the emergency measures in case of failure. Here are some common problems of the vibrating screen in the operation and their solutions. One. The screening effect of vibrating screen is not good Common vibrating screen mainly includes  linear vibrating screen , high frequency vibrating screen and circular vibrating screen. The reason for the poor screening effect varies with different  types of vi

Ball mill is a kind of grinding mill used in the mineral processing, which is to further grinding the material fitness to the appropriate particle size that meets the industrial requirement after the crushing process. At present, the ball mill machine is widely used in mine, cement, silicate products, building materials and other fields. 1.   Structure of ball mill: From the structure form, the  ball mill machine  can be divided into horizontal type ball mill and vertical type ball mill. The horizontal ball mill is used more and more widely with its simple structure. In brief, the ball mill machine mainly consists of rack and barrel. In particular, the structure of the ball mill machine includes the feed end, discharging end, rotary part, transmission part (including reducer, gear motor, electric control, etc.). The cylinder is equipped with the bearing (used to help the cylinder rotation), drivers, grinding media in the cylinder (the steel ball) and ball mill liner. 2.   Appl

As we all know, the cost of grinding operations accounts for a considerable proportion of the cost of the entire mineral processing plant. Since the grinding investment is huge and the energy consumption is extremely high, it’s widely agreed that “Without a mill, there exist no mineral processing”, from which we can see through clearly the importance of grinding operation. Therefore, the dressing plants are also very cautious in the selection of  grinding mill , in order to yield twice the result with half the effort. At present, the most widely used grinding equipment in the dressing plant is   ball mill  and  rod mill . As far as the working principle is concerned, both ball mill and rod millare the same. The grinding medium (steel ball or steel rod) installed in the cylinder is lifted to a certain height with the rotation of the cylinder under the action of friction and centrifugal force, and then thrown at a specific line speed to impact, grind and squeeze the materials in the

At present, the cyaniding process is one of the most widely used gold mining processes for the gold extraction, which can also be divided into many kinds of gold mining process, each of them needs different  gold mining machinery . Here are some common gold mining machinery used in the  gold mining process . Generally, the conventional  cyanide leaching process  includes three steps: leaching process, washing process, and zinc powder replacement process. In the CIP and CIL process, the activated carbon is used to extract gold, so the last step of these two processes becomes activated carbon adsorption process. The main gold mining machinery used in the cyanide leaching process includes the leaching agitation tank, high-efficiency low-consumption rapid desorption electrolysis system, washing thickener, zinc powder replacing device. Among them, the leaching agitation tank is applied to the conventional cyanide leaching process, the  CIP process  and the  CIL process . The desorpti
