Abstract
The utilization of low grade Hindubagh chromite for the preparation of chrome chemicals was studied. High purity sodium chromate and dichromate were prepared as main products. High purity sodium sulphate, alumina and chromium hydroxide were quantitatively obtained as valuable by-pro-ducts. Calcination temperature and lime content of the batch were observed to be critical. The use of sodium dichromate solution for the precipitation of alumina hydrate is preferred as it produces an easily filterable crystalline precipitate and is more economical.
