PROMOTERS FOR SOAP FLOTATION OF PHOSPHATE MINERALS

摘要

Detergents are being used in some phosphate ore beneficiation plants as promoters to enhance thernefficiency of the soap (or soap-diesel oil) flotation process. In the present investigation attemptsrnwere made to study the effect of promoters on the recovery of phosphate values from phosphaternore of Eshidiya mines, Jordan. Alfa Olefin Sulfonate (AOS), Linear Alkyl Benzene Sulfonate (LABS)rnand Urea were studied as promoters in conjunction with soap-light diesel oil emulsion. While AOSrnand LABS are detergents, urea is a polar non-electrolyte reagent known to act as hydrotrope. It isrnobserved that all the three promoters show enhanced flotation efficiency compared to flotation withrnsoap-emulsion. Interestingly urea along with soap-emulsion showed better performance comparedrnto AOS with soap-emulsion or LABS with soap-emulsion.
