THE SEPARATION OF CLAY MINERALS BY
Electrophoresis has been suggested as a method of separating clay minerals by Sill6n2 and by Beavers and Marshall (1951). It is only re-cently, however, that suitable equipment has become available (Strickler et ol., 1966, Strickler, 1967). The purpose of this study was to find a rapid method for separating clay minerals with a minimum change in

Heavy Mineral Analysis - Technique - Heavy mineral separation
The separation is done in a separating funnel in a temperature controlled room of 20°C. The “heavy” grains will accumulate in the bottom of the funnel above the pinch clip and the “lighter” grains float to the surface. After 6 – 8 hours of separation the pinch clip is opened and the heavy minerals are drained onto a filter paper.

Clay mineral X-ray diffraction - Wikipedia
Clay minerals are one of the most diverse minerals but all have a commonalty of crystal or grain sizes below 2 μm. Chemically clays are defined by crystal structure and chemical composition. Sometimes fine grain sediments are mistakenly described as clays, this is actually a description of the "clay-size fraction" rather than the mineralogy of the sediment.

Classic physical and chemical treatments applied to separating clay minerals from the host sediments are often difficult or aggressive for clay minerals. A technique using cation exchange resins (amberlite IRC-50H and amberlite IR-120) is used to separate clay minerals from the host sediments. The technique is based on the exchange of cations in the minerals that may be associated clay ...

The modern boron applications have adsorbed the mineral processors’ attention to improve typical boron mineral’s (BM) beneficiation methods. In this regard, dry treatment and pretreatment processes—such as magnetic separation and calcination as environmentally friendly methods, due to their minimal or zero adverse effect on the environment—need more consideration.
