Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in the production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons. It also occurs … Read more
Brief history of extracting tin from tin ores In nature, the tin ore are existing in sand or alluvial raw material, this kind of tin ore is called sand tin or alluvial tin, those raw materials may be stone, sand, gravel, soil, sticky clay, some times with other magnetic iron, tungsten, ilmenite, hematite, monazite, zircon … Read more
The magnetic separation process is mainly to carry out a three-stage magnetic separation treatment on the ore powder and then go through the wet material magnetic separation. The finished iron ore concentrate powder is obtained. Generally, the iron content of the ore is 35%. After magnetic separation by this method, the iron content of the … Read more
Tantalum and niobium ore beneficiation coarse separation is usually used the gravity separation method, also, the flotation, electromagnetic selection and electrometallurgical separation are used in a combined process, when dealing with powder or primary mud content of ore, washing and scrubber operations are essential, while the use of high-efficiency grinding and classification equipment to … Read more
Coal dust, the roar of machines, and the hard work of workers, these traditional coal mining scenes have become history in some coal mines in China. At present, the mining industry has become one of the most widely used fields of “5G + Industrial Internet“. According to statistics, there are about 5,300 coal mines in China, covering … Read more
The beneficiation process of quartz sand is mainly impurity removal and purification. To remove a small or slight amount of impurities in quartz sand and obtain a highly difficult separation technology of refined quartz sand or high-purity quartz sand. The quartz sand process mainly includes quartz sand impurity analysis and impurity removal process, quartz sand purification … Read more
The number of stages of the flotation process When determining the flotation process, the principle process (also known as the backbone process) should be determined first. The principle process only points out the principle scheme of the sorting process, which includes the number of separation stages, the sorting order of the components to be recovered, … Read more
The adjustment of flotation pulp includes pulp depth, PH value, etc., The depth and PH value will affect the flotation effect. In the flotation process, pH value has many effects on mineral flotation and is an important factor affecting flotation indexes. Following we will discuss the adjustment of pulp depth and PH value. Pulp Depth … Read more
There are more than ten kinds of tin-bearing mineral deposits. At present, tin used in industry mainly comes from cassiterite. Because the density of cassiterite is relatively high (6.4~7.1g/cm3), the primary method of beneficiation of cassiterite is reselection. However, because cassiterite is brittle, it is simply siltified in nature and in the process of crushing, … Read more
Study on Knelson Concentrator Gravity Separation of a Polymetallic Ore Bearing Gold The major methods of recovering gold are gravity separation, gold flotation, cyanide. In fact, traditional gravity separators, such as jig machine, spiral chute, gold shaker table, have the shortages of low beneficiation ratio and low productivity. In addition, the flotation process is difficult … Read more
