摘要：
The method of beneficiating a phosphate ore comprising apatite and including dolomitic impurities comprising reagentizing the ore having a particle size in the range of 75 .mu.m to about 420 .mu.m with an aqueous solution having a pH of from 3.5 to 4.5 and containing a fatty acid anionic collector and sodium chloride and subjecting the ore to froth flotation to float away the dolomitic impurities.
