Heavy Mineral - an overview | ScienceDirect Topics
The separating surface in the Reichert cone is in the form of an upward sloping truncated cone. The heavy minerals, in close contact with the cone surface pass through an annular slot near the bottom of the cone while the light fraction flows over the slot to be treated in another stage or permanently removed. The separation efficiency of the ...

Improved methods of heavy mineral separation and counting …
ABSTRACT A centrifuge tube for separation of heavy minerals in fine grained sands is designed so that the light and heavy components, even in small quantity, come out in separate containers. The heavy liquid stays relatively clear and its wastage is practically nil. Instead of the usual field method of counting grains, a `line method' of continuous traverse is used.

Heavy Media Separation Process - Mineral Processing
The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
