hydrocyclones (cyclones) hydrocyclones have become one of the most important and widely used classifiers in the mineral processing industry. they are also used for de-sliming, de-watering, de-gritting and thickening processes.
many of the particles encountered in mining are characterized by sieves (classifiers). recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. as particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

jigging of -5+1 mm fraction jigging of -5+1mm fraction was carried out and the result is portrayed in fig 2. jigging was done at a frequency of 70 strokes per minute with 600 l/min of water flow rate to the jig. jigging could improve the iron content in the bottom layer from 58.3
as is the trend in other aspects of mineral processing, unit capacity will increase as well as the degree of automation and process control. as environmental regulations and permitting requirements become more stringent, enhanced gravity concentration may become the only economically viable technology for some ore deposits.

in the process of jigging, corin applies two kinds of jigs to respectively separate the coarse and fine granularity of barite material. magnetic separation corin 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.
used in wet processes, eriez uses drum, roll, pulley and filter type magnetic separators in varying degrees of intensity to process dry minerals. these processes require conveyors, feeders and belts to present the material to the magnetic separators in underbelt, overbelt or gravity-fed applications.
