新型磷灰石常温捕收剂的浮选试验研究
Collecting Performance of New Collectors on Apatite at Room Temperature
摘要
Abstract
There still exist problems of pulp need to be heated,poor adaptability and too large the dosage of collector in apatite ore flotation.Thus,a new collector DYX had been prepared in order to solve the problems.And flotation experiments of single apatite was conducted.At the condition of temperature 26℃,pH 10.0,and DYX dosage 400 g/t,sodium silicate dosage 400 g/t,apatite recovery was 94.58％.The results show that the amount of DYX used is less.And the collector had strong collecting ability at temperate of 26℃.Mechanism Analysis according to the results of FTIR and zeta potential show that reactions between molecules of DYX,and the surface of the apatite are mainly hydrogen bond and chemical bonding adsorption.关键词
