The March issue of World Fertilizer magazine features an article in which ArrMaz’s Todd Parker, Global Marketing Manager Mining, and Guoxin Wang, Senior Director Global Mining Chemical Technologies, present case studies on how global phosphate processing challenges are being solved today.
The three ArrMaz case studies highlight the flotation results achieved for phosphate deposits in Africa, China and Florida. Each case study demonstrates how collector technology and flowsheet design can be married together and customized to individual ore characteristics, to optimize the rejection of calcite, dolomite, silica and other impurities, and enhance both phosphate grade and recovery.
ArrMaz has made significant advances in carbonate rejection, developing robust carbonate and silica collectors under its CustoFloat® and CustAmine® product lines, to beneficiate carbonate-laden phosphate deposits around the world. Many of these reagent solutions have been applied at full scale commercial plants, while others have been proven to work in pilot-scale flotation and laboratory testing.
Through these case studies, ArrMaz has proven that the global challenge of processing troublesome, carbonate-rich phosphate ores can effectively be solved by simultaneously developing an innovative reagent package, a custom flowsheet and a complementary equipment package together from the start. The future of global phosphate processing where reagent formulation, process flowsheet design and equipment selection are developed in unison is already here.
