Gypsum is a by -product of a green star phosphate manufacturing plant.
Agricultural Use:
Gypsum removes salt and alkalinity from the soil, more or less acting as a fertilizer.
Industrial Use:
Gypsum is used to make gypsum board. In the cement industry, gypsum is used to produce lime. Gypsum is also used to make alabaster.
White crystalline powder
Gypsum is an ideal soil conditioner, rich in calcium (23%) and sulfur (18%). CaSO4, 2H2O 90%, T-P2O5 0.50%
Aluminum fluoride (AlF3) is an inorganic compound primarily used in the production of aluminum. This colorless solid can be produced synthetically but also occurs naturally.
Used in the production of aluminum metal. Aluminum fluoride is an important additive for the production of aluminum by electrolysis. With Cryolite, the melting point is reduced to less than 1000 ° C, and the solution conductive rate is improved. The aluminum oxide is dissolved in this melted salt, which is electrolyzed to obtain a volume metal. Aluminum fluoride, when combined with zirconium fluoride, is an ingredient in the production of fluoroaluminate glass. It is also used to inhibit fermentation. This is a sputtering target for producing low index films.
Greenstar’s AlF3 process involves the reaction of aluminum hydroxide with hydrofluorosilicic acid. It is then filtered to remove the silicon, and the high-purity aluminum fluoride is then crystallized and dried. Greenstar’s Aluminium Fluoride is a trusted feedstock for leading aluminium manufacturers in India and across the globe, including Hindalco, Duval, Stellar and Foundry Services.

Silicon, also known as silicon dioxide (from the Latin silex), is a chemical compound with the chemical formula SiO2. It has been known since ancient times.
Silicon occurs most commonly in nature in the form of quartz, and is also present in a variety of living organisms. Silicon is one of the most complex and abundant groups of materials, occurring as multiple minerals and also produced synthetically.
In the chemical industry, silica is also used as a filter aid in phosphoric acid plants to improve recovery efficiency. The Greenstar process involves the reaction of aluminum hydroxide with hydrofluorosilicic acid followed by filtration to recover silica.
Its main clients are the Vedanta Resources group and Coromandel companies.
