Application of Hydrocyclone in Gold Ore Tailings

2020-5-26  1.Gold Tailings Filling. At present, most mines use tailings to fill the mined-out area. Tailings need to be desilted (-30-70um) to obtain high concentration (about 70%) tailings sand which also needs special treatment before filling. The requirement of tailings sand is to obtain the high-concentration grit by removing the fine-grained grade.
