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

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
