1. Could be used to mine gold mixed with sand in palaeochannel, palaeo-riverbed, alluvial placer, tailing after ball milling, and diamond and zirconium in raw ore.
2. Iron ore needs to be retrieved first with magnetic separator if the percentage is high in the raw ore, then gold, diamond, zirconium will be concentrated, or the effectiveness will be affected.
3. This set of mining equipment are composed of several gravity concentrators. The concentration ratio could reach as high as 1:1000, and the recovery efficiency about 90% after series of separation.
