Clay mineral separation by use of SPT heavy liquid

Abstract. Altered rocks associated with unconformity-related uranium deposits are composed of several kinds of clay minerals. In order to clarify detailed composition-paragenesis relationship, we applied heavy liquid separation using SPT (sodium polytungustate) solution, which specific gravity is controlable by dilution with water.

Clay Minerals from the Perspective of Oil and Gas Exploration

The clay minerals e.g. kaolinite, smectite, illite, chlorite, etc. are ubiquitous in the targeting rocks of oil and gas exploration. During the early age (1940s) of worldwide oil exploration, clay minerals were studied to predict the quality of organic rick source rock and generation mechanism when scientists tried to investigate the origin of oil and gas (Grim, 1947, Brooks, 1952).

Separation of clay minerals from host sediments using cation

2003/10/01 · 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
