2012-5-1  The process of grinding of rutile and barite crystalline powders in a laboratory ball mill in different types of gaseous media (air, nitrogen, helium) has been investigated. Comparative evaluations of the intensity of the dispersion of these minerals have been performed and the particle sizes of powders obtained in different modes of their dispersion have been measured.

Barite an overview ScienceDirect Topics

Barite (BaSO 4) is a widespread mineral in deep-sea sediments, varying between 1% and 10% by weight on a carbonate-free basis.It is the predominant Ba phase in the ocean. BaSO 4 is known to compose a solid solution series with SrSO 4 as celestobarite in the skeletal portions of some marine organisms (i.e., the Xenophyophoria) and is often found in association with marine organic matter, such

Prediction Models of Barite Crystallization and

There are two major types of barite inhibition testing methods in the oil and gas industry: the dynamic loop test and kinetic turbidity test methods [15,16,17,18,19]. In the dynamic loop test, the inhibition efficiency is evaluated based on the blockage of flow loop, which could be detected by measuring the changes of ion concentrations or pressure [ 16,17,18,19 ].
