What are the flotation agents for silica?
Silica is an acidic oxide. There are many silica ores in nature, such as quartz. From the physical properties, silica has high hardness and high melting point. In the field of mineral processing, the flotation of silica is an important process, and the selection of suitable mineral processing agents is the key to achieving efficient flotation. This article will discuss in detail the types, characteristics and functions of silica flotation ore reagents....

Beneficiation technology of different types of lead-zinc ores
Lead-zinc metals are widely used in electrical, mechanical, military, metallurgical, chemical and other fields. With the increasing demand for metals year by year, it is urgent to improve the recovery rate of metal ores in ores. Oxidized lead-zinc ores can be divided into three types according to the degree of oxidation: sulfide lead-zinc ores, oxidized lead-zinc ores and mixed lead-zinc ores. Among them, sulfide lead-zinc ores and mixed lead-zinc ores can be treated by flotation, while oxidized lead-zinc ores need to be treated by flotation in addition to beneficiation metallurgy or single metallurgy due to their fast oxidation rate, high mud content and close symbiosis with limonite. The following will introduce the above three beneficiation technology of lead-zinc ores respectively....

Low-grade bauxite beneficiation method
Bauxite is a mineral composed of gibbsite, boehmite or diaspore, and its main chemical component is alumina (Al₂O₃). Bauxite is the main raw material for the production of metallic aluminum, and is also widely used in refractory materials, abrasive materials, chemical industry and other fields. With the rapid development of the aluminum industry, high-grade bauxite resources are decreasing, and the development and utilization of low-grade bauxite is becoming more and more important. This article introduces low-grade bauxite beneficiation method!...

What are the mica flotation methods?
Mica is a common layered silicate mineral with good electrical insulation and heat resistance. It is widely used in electrical, electronic, building materials and other fields. Due to the particularity of its physical and chemical properties, flotation is usually used to extract mica from ores. At present, the commonly used mica flotation methods include acidic cation flotation, alkaline cation flotation, alkaline anion flotation and combined flotation....

Factors affecting the flotation efficiency of quartz sand
As one of the most common minerals in the earth's crust, quartz sand is widely used in industries such as glass, ceramics, and metallurgy. However, natural quartz ore is usually accompanied by a large amount of impurities. In order to improve the purity of quartz, it must be processed by flotation and other mineral processing processes. In the process of quartz sand flotation, factors such as particle size control, slurry concentration, foam properties, water quality, temperature, and flotation equipment will directly affect the flotation effect. Reasonable control of these parameters can effectively improve the efficiency of the flotation process and maximize the purity and recovery rate of quartz....
