Gravity separation process of the ore is made up of a series of operations. The nature of the job can be divided into preparation, separation operations, product processing operation into three parts.

(1) preparation, including a: for useful mineral crushing and grinding in the monomer dissociation; b: many plastic or clay-bearing ore washing and desliming; c: use of screening or classification of hydraulic method of selected ore particle size classification. Ore graded WINS, respectively, conditions conducive to the selection operation, improve separation efficiency.

(2) separation operation, is the subject of ore sorting links. Dressing process simple with complex, simple consisting of unit operations, such as heavy medium separation.

(3) product processing operation mainly means concentrate dewatering, tailings conveying and storage.
