B & M Chemicals Limited
Chromite Ore, a complex mixture of chrome, Aluminium, Magnesium, and Iron is the starting point for the range of products. In our process, chromite ore is first ground and then roasted at high temperature in large furnaces with soda ash in the presence of oxygen to produce a first contaning Sodium Chromate. This is leached with water and the Sodium Chromate extracted and reacted with Sulphuric Acid to give a commercially pure solution of Sodium Dichromate. Sodium Dichromate either in solid or liquid form is widely used in Industries and is also the starting point for the manufacture of all other chromium chemicals.
