The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu
Bachelors Theses and Reports, 1928 - 1970
In this thesis I have tried to determine the suitable temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. Therefore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.
