Diamond Separation Technology and Equipment

Diamond is kind of mineral composed of pure carbon. As kind of hardest material in nature, it is used widely, eg. cutting instrument of artware or in other industries. As a mineral, its content is very low, and rough separation and fine separation and other separation can be involved to get the diamond from the low content ore.

A general learning about the diamond type and characteristics is needed to get the diamond granules. There is protogenesis diamond ore and placer diamond ore. Protogenesis diamond ore is mainly kimberlite which consists mainly of Olivine, pyrope, phlogopite, chromite, ilmenite, apatite, moissanite and secondary of magnetite, serpentine, chlorite and calcite. Composition of placer diamond ore can be different because of different deposit formation. A diamond deposit in Changde, Hunan, China mainly consists of diamond, gold, titanium iron, hematite, magnetite, zircon sand, rutile, garnet, diaspore with the light minerals of quartz, feldspar, mica, opal etc..

The processing of diamond ore is generally divided into two phases-rough separation and fine selection. The rough separation is mainly gravity separation while the fine selection is decided by the specific of the diamond ore itself.

The diamond rough separation can be pan washing, jigging separation, heavy medium separation and during these three methods, diamond jig separation is used most commonly because of its simple operation, good efficiency, and high recovery as an ideal separation for diamond rough separation. Here jig separator is the ideal diamond rough separation equipment especially for placer diamond ore.

The fine selection of diamond ore is handy selection, electric separation, factice separation, and X-ray separation. During these methods, factice separation and handy separation is used most commonly. Handy separation can help to get the big granules of diamond while the factice can help to get the small diamond granules with recovery of 90-98%.

The separation of diamond is not so easy and not only one set of jigger or factice can finish the job to get diamond. Recently there are a few clients asking about the diamond separation and most of them do not learn more about the diamond separation. Both separation machine-diamond jig separator and diamond separation technology is needed to guarantee the separation efficiency and recovery. For diamond jigging machine, material, density, thickness of medium and the sieve hole size shall be considered. Even a little error can lead to loss of diamond or low recovery. So both diamond jigger and precise adjustment technology can be must to get diamond to a biggest extent. The following is about the diamond jig separator and factice diamond separator:

Here Forui has designed flow sheet with plant allocation. Diamond jig separators and factice diamond separators have been praised by clients. Here small test can be supplied if samples can be available. It will be a great honor to share with you more about the diamond separation
