ABSTRACT:
A process for purifying calcium carbonate ore by the removal of silicate impurities from the ore by reverse flotation. The process achieves high yields and low acid insoluble content of the calcium carbonate product by employing novel collectors. These novel collectors which characterize the invention comprise organo-nitrogen compounds including propoxylated quaternary ammonium compounds, unsymmetrical dialkyl dimethyl quaternary ammonium compounds and dialkyl hexahydropyrimidine compounds.
