For a certain tin ore dressing plant, we have taken flotationgravity process by smashing raw ore to 200mm, and a closecircuit grinding by grinding it to 200mm occupied 60~ 65% . Process of "one roughing two scavengingone cleaning" has been applied to the flotation to grind copper and sulfur separately to occupied 95%.
Gold. In southern Africa, two xray sorters are used to preconcentrate sulphide gold ore into two different grain size egories. While the input material has an average gold content of less than g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.

A process for upgrading lowgrade magnetitecontaining iron ore with minimum fine grinding. The dry ore is first comminuted to between about threefourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
