[Process  Description]

Gravity Separation

For the gravity separation of barite, the  process of Xinhai is crushing, screening and jigging. Then the high grade (over  80%) concentrate will be produced. Jig is the main equipment for the separation  and purification of barite ore, which is energy saving, high efficiency, and  environment protection. In the process of crushing, Xinhai uses jaw crusher and  applies two-stage crushing process. In the process of screening, Xinhai uses simple and useful circular vibrating screen, which also have the  features of large capacity, high efficiency, and convenient operation. It is  very suitable for screening of barite ore. In the process of jigging, Xinhai  applies two kinds of jigs to respectively separate the coarse and fine granularity  of barite material.

Magnetic Separation

Xinhai usually applies wet magnetic  separation to beneficiate some iron-bearing mineral, like siderite, which  applies to barite ore that is used in barium-based medicine requiring low iron  barite.

Floatation

As for the barite with fine particle size  and gravity tailings, Xinhai applies process of floatation. According to the  different adsorption manner, Xinhai uses some anionic collector, like fatty  acid alkyl sulfate, alkyl sulfonate, or cationic collector, like amide  collectors to do the floatation for barite ore.

[Case]

For example, Xinhai had a project for the Separation,  purification and processing of barite. In this processing, Xinhai applied  floatation for the tailings with BaS048%~15%, then gets concentrate grade with  BaS0488%, a share of 4.35%, and recovery rate of 81%. It had gained excellent  economic benefit.
