A tailings pond is a place composed of dams to intercept valley mouths or enclosures and is used to store metal or non-metal mines for ore sorting and discharge tailings or other industrial waste. A system of structures constructed for tailings disposal is called a tailings facility. In this article, we will introduce the composition, … Read more

Adjust the distance between the magnetic drum and the dividing plate The distance between the separation plate and the magnetic drum is an important parameter in the pre-selection process. The smaller the distance between the separation plate, the better recovery of the lean magnetite blocks, which reduces the utilization rate of ore resources; the separation … Read more

Flotation of lead-zinc sulfide ore Lead and zinc are one of the earliest metals extracted by humans from lead-zinc ore. They are widely used in the electrical industry, machinery industry, military industry, metallurgical industry, chemical industry, light industry and pharmaceutical industry and so on. In addition, lead metal also has many uses in the nuclear … Read more

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
