Aluminum chloride (AlCl₃) is an inorganic chemical raw material. It appears as a white or light yellow crystalline powder and is highly soluble in water, ethanol, ether and other solvents. It is prone to deliquescence in the air and produces hydrogen chloride fumes. It has strong corrosiveness and hygroscopicity. According to differences in purity, form and application, aluminium chloride can be classified into multiple categories such as industrial grade and reagent grade, and is widely used in water treatment, chemical synthesis, metallurgy and other fields

Citric acid， It is an organic acid that naturally exists in citrus fruits and can also be produced on a large scale through biological fermentation processes. It appears as colorless transparent crystals or white powder, odorless, extremely sour in taste, and readily soluble in water and ethanol. It has multiple functions such as acidity regulation, chelation, scale removal, and preservation and anti-corrosion.

Main uses：Mineral processing reagent

Main features：As a strong collector, it has a remarkable effect on the flotation of copper, zinc, nickel and pyrite containing gold, especially suitable for refractory copper oxide ores and lead oxide ores

Application scenarios：It is widely used in the ore separation process of the mining industry, especially in the flotation of oxidized sulfide ores (such as copper, nickel and lead ores) and pyrite containing gold, which can increase the recovery rate of gold and copper

Main uses：Nonionic surfactant

Main features：

It is mainly used in the production of high-performance detergents, printing and dyeing auxiliaries (such as scouring agents and softeners), textile oiling agents, pesticide emulsifiers, etc. It can also be used as an anti-wax agent for oil fields or a wetting agent for investment casting

Sodium cyanide is a white crystalline powder at normal temperature and pressure. It is highly soluble in water, and its aqueous solution is strongly alkaline.

Sodium cyanide is an important chemical raw material, mainly applied in the following fields:

Electroplating industry: It is used for electroplating and surface treatment of metals, which can enhance the smoothness and adhesion of the coating.

Metallurgical industry: It is used for extracting precious metals such as gold and silver. By taking advantage of the property that cyanide ions form stable complexes with precious metal ions, it achieves the enrichment and separation of precious metals.

Organic synthesis: As an intermediate, it is used in the manufacture of drugs, dyes, pesticides and other chemicals.

Calcium hypochlorite ，Bleaching powder, commonly known as bleaching powder, is a highly efficient inorganic chlorine-containing disinfectant.
