Most gold mine tailings are composed mainly of industrial sand (i.e., silica) and silica sand is best described as a granular material that is composed of majorly quartz and trace amounts of coal, clay and other minerals [].In some instances, it is referred to as either quartz or industrial sand and is widely applied in many engineering applications.May 26, 2020 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.
