A tungsten ore dressing plant in China has fully adopted the principle of jigger 'collect more early, throw away early', the plant, in addition to the roughing section and early hand-picked massive tungsten ore and large tungsten contiguous body in addition to re-election processing, give full play to the ability of jigger recovery of coarse-grained metal minerals, the whole field using eight jigger, the recovered WO3 accounts for re-election section of the The recovery of WO3 accounts for about 70% of the re-election section, which fully reflects the feature of using jigger to 'collect more as early as possible, and lose as early as possible'.

Jigger process design should consider product quality, comprehensive recovery, rich and poor sorting, mud and sand sorting, difficult and easy sorting, early collection of more useful ore, early loss of more waste rock or tailings. In modern mineral processing practice, jigger in addition to directly as the main sorting equipment, also commonly used to pre-infiltrate unevenly in the ore of coarse-grained minerals out of the next step in the selection before fine grinding due to the loss of metal caused by the state crushing, and reduce the consumption of ball milling equipment and costs. Jig concentrator beneficiation method in addition to separate use, but also often with other beneficiation methods used jointly. For example, in the flotation method of separation of non-ferrous metal ores, in the discharge of the mill with jigger recovery ratio of precious metals (such as gold, silver, platinum). China's various tungsten and tin beneficiation plant, it is common to use jigging beneficiation method and shaking table beneficiation method jointly, that is, jigger processing coarse-grained level, shaking table processing fine-grained level. Jigger processing capacity is large, high recovery rate, simple mechanical structure, convenient operation and maintenance, can sorting wide level of minerals. The sorting particle size of metal ores is divided into 50-0.074mm.

Jigger is also a gravity separation equipment, which is mainly used for coarse, medium, fine-grained embedded minerals beneficiation, for micro-fine-grained embedded minerals beneficiation efficiency is not good, in most of the sulphurous iron ore in the combination of sulphur and iron embedded in the particle size is coarse, generally in more than 1mm, the selection of these iron sulphur can be sold directly to the sulphuric acid plant to obtain the benefits. In sulphide iron ore beneficiation, the application of jigger is extremely wide, both as coarse grained sulphide iron ore washing equipment, but also as fine grained sulphur gold sand selection equipment!
