Iron sphalerite is one of the main zinc ores, usually in yellow, brown, black, etc., and is a brittle mineral with a hardness between 3.5-4. As one of the main sources of zinc, sphalerite is widely distributed in the earth's crust, often accompanied by other sulfide minerals such as pyrite and chalcopyrite. Zinc is used industrially for galvanizing, alloy preparation, battery production, chemical raw materials, etc. As an important zinc ore, zinc metal can be obtained through flotation extraction and separation of concentrates or used in the production of zinc compounds.

Lepidolite mineral processing technology and equipment is a process used to extract valuable minerals such as lithium from lepidolite ore. The ore typically contains lithium minerals such as spodumene and lepidolite, which are critical to the production of lithium-ion batteries. The beneficiation process involves multiple stages and requires specific technology and equipment. The following is an overview of the techniques and equipment used in this process.

Tungsten ore is an important mineral resource widely used in steel, aerospace, electronics and other fields. However, the recovery rate of tungsten mineral is generally low, resulting in waste of resources and environmental pollution. Therefore, it is of great significance to improve the recovery rate of tungsten mineral beneficiation. This article will discuss how to improve the tungsten ore beneficiation recovery rate from aspects such as the raw ore properties of tungsten ore, tungsten ore beneficiation process selection, tungsten mineral beneficiation plant equipment configuration, and tungsten ore beneficiation plant operation management.

According to the dissipation characteristics of the ore, scheelite can use gravity separation, a combination of gravity separation and flotation, or a single flotation method. Different scheelites have different types and contents of associated useful minerals, so their ore processing methods are also different. The following will introduce to you the gravity separation process of coarse-grained scheelite and the flotation process of fine-grained scheelite.

Hematite is a weakly magnetic mineral and can be processed using a variety of beneficiation processes, such as gravity separation, flotation, strong magnetic separation, roasting magnetic separation, etc. However, different types of hematite require different ore beneficiation methods. The following will introduce you to several hematite beneficiation methods.

Magnetite is widely distributed in nature and is often found together with hematite and manganese ore. It has strong magnetic selectivity and is one of the main ores of iron ore, so it can be used to smelt iron and steel. As an important ore, magnetite also has important value in the metallurgical industry and other fields. Commonly used magnetite ore processing methods mainly include: single magnetic separation process, weak magnetic separation-cation reverse flotation process, weak magnetic separation-anion reverse flotation process, full magnetic separation process and ultra-fine crushing-wet magnetic separation tailing process.

As a commonly used metal raw material, iron ore can be processed by a variety of beneficiation methods, such as magnetic separation, flotation, gravity separation or combined beneficiation methods. Before iron ore beneficiation, a series of pretreatment processes are required to improve the processing efficiency of the product. Since different types of ores have different properties and separation characteristics, it is necessary to adopt appropriate beneficiation methods to recover the valuable components in the ores as much as possible.

The grinding process of a phosphate ore dressing plant generally forms a closed circuit with the classifier or hydrocyclone. Phosphate rock grinding can adopt one-stage grinding or stage grinding. The number of grinding stages and processes generally need to be determined based on the characteristics of the phosphate ore, the requirements of the concentrate product, and the production capacity. Siliceous apatite has medium hardness and coarse dispersion particle size, so it can adopt a one-stage grinding process. However, when processing colloidal phosphate ore, the product particle size is required to be fine and the productivity is high, so it is necessary to increase the number of grinding stages. Therefore, different types of phosphate rocks use different grinding processes.

Tungsten is widely used in cemented carbide, steel and special alloys, lighting industry, chemical industry, petrochemical industry, and high-tech fields. As the tungsten market demand becomes stronger, the recovery rate of tungsten ore needs to be increased to meet market demand. Depending on the mineral, different mineral processing methods are used. In order to improve the recovery rate, it is necessary to choose the appropriate mineral processing method. At present, the tungsten minerals with economic value for mining mainly include wolframite and scheelite.

Gold, as a precious metal, has many advantages like stable chemical property, corrosion resistance and dis-oxidization.it can widely used in Jewelry, electronics, medical, aviation, construction and other industries. With the gradual depletion of gold ore resources, how to improve the utilization rate of gold ore resources and recover gold from low-grade gold ores has gradually attracted attention. To improve the recovery rate of gold mines, it is necessary to choose appropriate mineral processing methods.

Gold occurs in various states in primary ores. According to this characteristic, cyanidation, gravity separation, magnetic separation, flotation and other methods can be selected to extract gold. Flotation is one of the important methods for treating gold-bearing ores. The flotation process includes material preparation, adjusting the pH value of the slurry, adding flotation reagents, flotation and other processes. The following will mainly introduce to you the characteristics of gold mines using flotation methods and the flotation methods of different types of gold mines to help you better understand gold mine flotation methods.

There are many kinds of gold ores in the nature, and the beneficiation methods chosen for different types are naturally different. Among them, the commonly used beneficiation method in rock gold mines is mainly flotation. The flotation method can process poor sulfide gold ores, high sulfide gold ores and associated polymetallic gold-bearing ores. It can effectively separate various gold-bearing sulfide concentrates. The commonly used method is the priority flotation process to directly float out gold-bearing sulfide ores. In addition, flotation is also an indispensable method for treating refractory gold- and silver-containing ores that are difficult to directly mix with mercury and cyanide. In production practice, the appropriate flotation process can be selected based on the properties of gold and silver ores and product requirements.
