摘      要：The technological mineralogy of the potash feldspar was investigated and a new collector named Yb105 was adopted to remove iron from potash feldspar *** technological mineralogy results indicate that the main components of the ore were feldspar,sericite,quartz and kaolinite,and iron mainly existed in limonite and hematite,most of which can be removed by *** results show the benzohydroxamic acid can not only increase the recovery of iron and reduce the consumption of oleic acid collector,but also enhance the collecting performance of oleic acid at low temperature,which can realize the flotation of the ores at a low temperature and play an important role in saving energy to some *** with oleic oil,the benzohydroxamic acid had a great advantage in removing iron from potash feldspar,a potash feldspar concentrate with Fe grade of 0.23%,K2O grade of 12.59%and Na2O grade of 0.26%was obtained by flotation with Yb105 as collector,and the yield of the concentrate was 82.55%.
