PROCESSING OF SALT FOR CHEMICAL AND HUMAN CONSUMPTION

摘要：

The presence of impurities in salt has serious economic and environmental consequences. Impurities increase the cost of brine treatment in chloralkali plants, magnify the problems of contaminated effluent disposal and necessitate costly refining of salt for human consumption. The hydromechanical salt processing ranges from salt washing to counter-current purification with hydroextraction of impurities.This paper examines the nature of impurities in salt and explains the unit operations employed in the hydromechanical salt processes. It describes the salt testing methods relevant to prediction of the process performance, defines process efficiency and presents results obtained in industrial salt processing plants.
