Improved Recovery Of Florida Phosphate Rock By Modifying Standard 14-m3 (500-Ft3) Wemco Cells With 28-m3 (1000-Ft3) Cell Mechanisms

Since the introduction of froth flotation, the Florida Phosphate Industry has faced the challenge of coarse particle -850 +425µm (-20 +35 Tyler mesh) beneficiation. Several techniques have been used to upgrade this difficult size range. This paper discusses one approach that has met with success; namely, improved fractional recoveries through enhanced areation and improved material transport characteristics via larger than standard flotation cell mechanisms.
