FLOATATION METHOD FOR SEPARATION AND RECOVERY OF QUARTZ AND OTHOCLASE FROM OFFSHORE SAND

摘要

The beach sand is washed to remove the clay and then floatation for separation and recovery of colored gangue, mica and fine othoclase is made on condition of acid solution (pH 3.0-4.5) by adding HF. And later the deposition is floated for sepsration and recovery of quartz and othoclase on condition of alkali solution (pH 9.5-10.0) by adding NaOH.
