» Aluminium Hydroxides & Oxides : |
The Aluminium Hydroxides & Oxides (generally termed collectively as "alumina") are produced from Alumina Tri-Hydrate - an intermediate from the bayer process used for producing primary aluminium from bauxite. Anjaria Enviro Tech markets the following grades of Alumina: |
• |
High Purity Finely Precipitated Pseudoboehmite Alumina |
• |
Other Finely Precipitated Alumina |

|
High Purity Finely Precipitated Pseudoboehmite Sol-Gels : |
The Anjaria high purity boehmite alumina are available as white, free-flowing, finely precipitated & ground powders. The manufacturing process for Anjaria Pseudoboehmite starts with Alumina trihydrate and is precipitated under controlled conditions to yield aluminas that have high surface area and adequate pore volume - necessary for catalyst activities. The high purity is obtained by removing/ controlling the impurities at various stages of manufacture to obtain final product with less than 0.5% of total impurities. The products basically consist of small boehmite crystals, often referred to as pseudoboehmite, and the crystalline character of each different grade is controlled in order to obtain the desired chemical and physical properties. The typical applications include chemical catalysts, automotive washcoat catalysts, catalyst binders and supports, sol-gel abrasives, polishing compounds, viscosifiers and anti-skid agents. The company at present manufactures alumina catalyst grade and catalyst binder grade aluminas. |

» Wet, Dried & Ground Alumina: |
The wet alumina is the Alumina Tri-hydrate produced from the bayer process. Anjaria Enviro Tech does not manufacture the product, but markets the same under its own brand. The dried alumina is the dried form of the above material, and we produce and market the same. The Wet and dried hydrates are mainly used as raw material in the production of synthetic zeolites, aluminium compounds, glasses, ceramics, refractories, & other chemical products. The ground aluminas are mainly used in the production of fused white, ruby and pink corundum; tabular alumina; glazes and frits; glasses; household- ceramics; engineering – ceramics; refractories, polishing and abrasive materials. |

» Copper / Manganese / Nickel / Zinc - Salts, Carbonates, Hydroxides & Oxides Copper / Manganese /Nickel /Zinc Salts : |
These are produced from reacting respective secondary sources (or waste, or by-product, in layman terms) of metal with sulphuric acid / nitric acid / hydrochloric acid & treating the crude product for removing/ controlling the impurities to produce required grade of the finished product. For example, for producing copper sulphate, copper ash or dust produced as a by-product from a metal finishing industry is reacted with sulphuric acid of required concentration & treated to remove balance impurities including arsenic, iron, lead, zinc, etc. to obtain copper sulphate of required specifications. Sometimes, two or more metals are present in appreciable quantities in the secondary source and have to be separated and recovered individually to obtain both or more (as the case may be). The price of the secondary source depends on many factors: |
• |
first - the purer the secondary source, the nearer is its price to the virgin metal; eg. The price of 70% zinc ash will be much nearer to its metal price as compared to 40% zinc ash, as the ease of processing 70% is less than half than that required for, processing 40% zinc ash. |
• |
second - the ease of separation & recovery of metals from the source; eg. It is easier to process brass ash to recover copper and zinc than to process zinc-aluminium ash as zinc & aluminium are difficult to separate. |
• |
third - the processing cost for recovery and |
• |
fourth - the demand for that particular metal / salt. |
|
|
The major products under this category, which the company manufactures & markets are |
1 |
Copper Sulphate - CuS04.5H20, is the most widely used of the copper salts, withcurrent world consumption at 2 lac MTA-75% in agriculture as a fungicide.

Its major uses are in electroplating copper on iron; as a catalyst and nitrating agent in organic reactions; component in rocket fuel; fungicides and wood preservatives; textile dyeing and printing; pigment in ceramics; and in photography. |
3 |
Manganese Sulphate - MnSO4 form very stable, nearly white crystals that are extremely soluble in water. It crystallizes out of aqueous solution as pink hydrates, bellow 9 degree celcius, Monoclinic Heptahydrate is obtained (MnSO4.7H2O), between 9 and 26 degree celcius, the Triclinic Pentahydrate (Manganese Vitrief) MnSO4.5H2O, between 26 and 27 degree celcius, the Rhombic or Monoclinic Tetrahydrate (MnSO4.4H2O) is obtained. Between 35 and 40 degree celcius commercial form of MnSO4 - Manganese Sulphate is obtained and above 27 degree celcius the Monoclinic Monohydrate (MnSO4.H2O) is precipited. Its major uses are in agricultural and for production of agro-chemicals; as a material of other magnesium salts; in pharmaceutical industry; dying industry, etc. |

Zinc Chloride - Zinc chloride (ZnC12) is a colorless or white compound of zinc and chlorine that is extremely hygroscopic. The major uses of zinc chloride are in manufacture of batteries; in textile processing; metallurgical fluxes, soldering flux; and chemical synthesis. ZnC12 has also been used as a fireproofing agent and for etching metals. In the laboratory, zinc chloride finds wide use, principally as a moderate-strength Lewis acid. |
5 |
Zinc Sulphate - It is clear, crystalline, Water soluble salt of zinc, existing in mono-hydrate & hepta hydrate forms. The hepta-hydrated form, ZnS04-7H2O, the mineral goslarite, was historically known as "white vitriol". Zinc Sulphate is used to supply zinc in animal feeds, fertilizers, and agricultural sprays; in making lithopone; in coagulation baths for rayon; in electrolytes for zinc plating; as a mordant in dyeing; as a preservative for skins and leather; and in medicine as an astringent and emetic. |
