ОТЕЧЕСТВЕННЫЕ ФОСФОРСОДЕРЖАЩИЕ ПАВ-АКТИВНЫЕ СОБИРАТЕЛИ КОМПЛЕКСНОГО ОБОГАЩЕНИЯ АПАТИТ-НЕФЕЛИНОВЫХ РУД

The possibility of using domestic phosphorus surfactant as fl otation reagents for the separation of apatitenepheline dirt deposits of the Khibiny. The purpose of study is to obtain high-quality apatite (P2O5 > 39 %) of the original ores and nepheline concentrate (Al2O3 > 28 %) of the product chamber fl otation of apatite. The main characteristics of the original apatite-nepheline dirt, studied their chemical and mineralogical composition. Apatite concentrate obtained direct fl otation on the open and closed loop. As fl otation reagents – collectors used for the separation of apatite phosphate esters imported and domestically produced. Nepheline concentrate was prepared using a reverse fl otation. Comparative analysis of the obtained results show that the proposed domestic fl otation reagents unlike imported counterparts, more technologically advanced and effi cient, while their cost is lower. Using a specially developed collectors for fl otation of nepheline allows to increase the yield of 50 % and signifi cantly improve the quality of the concentrate.
