Indicators And Influencing Factors Of Grinding And
Oct 01, 2020 The grinding classification process implemented by the industrial gold ore plant in Jeollanamdo province, Korea is composed of a two stage circuit. The first stage is an open circuit of the first ball mill and a spiral classifier, while the second stage is a closed circuit of the second ball mill and a hydrocyclone, as shown in Fig.The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au Ag tellurides, and very fine grained gold ( 10 m) locked.
