Chemical appearance: Sodium cyanide is found either in the white crystalline form or in the form of granular powder. It is also water-soluble and forms a clear and colorless aqueous solution. Chemical application and strengths: The most important application of sodium cyanide is evident in the extraction of gold. The use of sodium cyanide is still the best method for mining gold. Sodium cyanide is a common agent in the leaching process for the majority of gold extraction operations. The primary reason for the use of Sodium cyanide in the extraction of gold is the higher affinity of gold towards cyanide. Sodium cyanide separates gold through oxidizing it and dissolving gold in the presence of oxygen and water. The most important strengths of sodium cyanide in the mining of precious metals are reflected in its cost-effectiveness, higher availability, and better processing CAS Number:143-33-9 HS Code:283711

Chemical appearance: Copper (II) sulfate pentahydrate is a blue crystalline solid. It is not combustible and has a strong, nauseating metallic taste. However, it is odorless. When dehydrated, it turns white. Chemical application and strengths: Copper sulfate is made by treating copper with hot concentrated sulfuric acid. The crystal combines with other elements for the preparation of different compounds. In its pure nature, it is used as fungicide. It is also mixed with sodium hydroxide to control fungus in melons and grapes. Copper sulfate is used in swimming pools as an algaecide. It is also used for the control of invasive plants in the pools and controls roots that may have punctured the piping system. Fish farmers use it to kill off the invasive types of snails in aquariums. However, its use in the aquarium is highly controlled, as it is toxic to fish in high quantities. CAS Number:7758-99-8 HS Code:283325

Chemical appearance: The appearance of Sodium metabisulfite is either in the form of white crystals or as a powdered solid with a slight odor of sulfur. Inhalation could lead to toxic results and can cause serious damages to skin and tissue. Sodium metabisulfite is clearly soluble in water and forms a clear and colorless solution. Chemical application and strengths: The primary applications of Sodium metabisulfite are evident in the mining industry. It is used for controlling the depression of pyrites and sphalerite minerals. MBS is ideal for pH control for the froth flotation process, where it could control pyrite depression. Sodium Metabisulfite is also helpful in preventing flotation of sphalerite through copper activation with the availability of Tennantite/Covellite in the ore. In the case of pyrite flotation, the maximum iron/pyrite depression with the use of Sodium Metabisulfite is possible somewhere around the pH of 6. CAS Number:7681-57-4 HS Code:283210

Phthalic Anhydride is most commonly used for the large-scale production of plasticizers for plastics. It performs the useful functions of fillers for products such as paints, plastics, and textiles etc. It is used in the production of building material. It is utilised for making insulating material for protection from noise and cold etc. such as in homes and buildings. It is also consumed for making insulation for wires and electrical cables. In the chemical industry it acts as a modifier for chemicals. It is widely used for the efficient production of colourants. It is used for making dyes and pigments. CAS Number:85-44-9 HS Code:29173500
