Basic chromium sulphate and waste management

To start production of basic chromium sulphate, raw chromium ore is brough from Ingassana area inform of rocks, crushed into small particles with particle size of nano structure. The chromium ore particles' are roasted with soda ash to sodium chromate which is then oxidized to sodium dichromate. Sodium dichromate is reduced with molasses and sulphric acid at 98% concentration to basic chromium sulphate. The basic chromium sulphate analysis are 26%Cr2O3 and 33% basicity which is suitable for tanning of leather to wet –blue stage. After completion of the tanning process.The spent to chrome liquor is recycled after being topped with the required level and reused. The management of the spent chrome is very important and the recycling process protects the environment, saves chemicals, water and reduces the cost.
