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. 2. This process currently handles 5.9 t/h of the gold ore

Hello everyone, 1. a 40 000 tpd plant with a 15 MW primary SAG mill and 2 pcs 10 MW secondary ball mill. If you try to change the H/C feed pump without stopping or just during a short shut down of the grinding line, you may not get a single drop of slurry into the stand by pump because the feed sump is half full of ball scrap and coarse rock, blocking the pump inlet pipe of the standby pump
