Abstract

Optimum conditions have been worked out for preparing freeflowing table salt marine salt. the process involves puriflcation of the salt with lime and soda ash and crystallization under controlled conditions so as to produce grains of size and shape conducive to the free-flowing quality. coating the salt with a drier and paraffin wax insures this property under varying climatic conditions. cost estimates indicate that a one-ton-per-day plant would give a 21.5 per cent return on investment.
