【Process Description】

Crushing  and Screening

Crush the raw ore to 20mm, then screen it  to two grade, (20mm~4mm) and (4mm~0mm).

Preselecting

Put the 20~4mm ore into heavy medium  cyclone to be selected. Then the ore will enter into the rod mill. After that,  it will be preselected in jig. The tailings over 2mm will be abandoned, the 2mm  ore will be put into shaking table.

Bulk  Flotation

The concentration from jig and shaking board  will be separately selected by bulk flotation. The tailings will enter the  shaking board to get qualified tin concentrates.

Separating  Flotation

After the bulk flotation, the concentrate  will be fine grinded, then will be do the flotation separation of lead zinc ore.  After that Lead antimony concentrates and zinc concentrates will be  produced.

Gravity  Separation

The tin pulp enter into Φ300mm  hydrocyclone, then overflow to Φ125mm and Φ75mm  hydrocyclone group to  remove the fine mud. The sand setting will enter into the process of  thickening, desulphurization by flotation, and then cassiterite flotation.

【Case】

For a certain tin ore dressing plant, Xinhai has taken flotation-gravity process by smashing tiningraw ore to 200mm, and a close-circuit grinding by grinding it to 200mm occupied 60~ 65% . Process of “one roughing- two scavenging-one cleaning” has been applied to the flotation to grind copper and sulfur separately to 0.074mm occupied 95%. It also can get copper concentrate and sulfur concentrate through one roughing- two scavenging-one cleaning. Thereafter, using mixed flotation method can access to the aim of doing gravity process after tailings in sulfide and passing to one or two separation by shaking table, and one complex wash. It gets tin ore after slime flotation and finally tin concentrate by desulphurizing.
