bentonite and barite separation

Impact of barite and ilmenite mixture on enhancing the ...

2018-12-1  Barite/ilmenite mixture has the potential to be used as alternative weighting material to barite in drilling mud technology. SEM micrographs of Na-bentonite, barite and ilmenite particles were investigated to illustrate the morphological shapes of these particles and give an idea about the expected weighting mechanism via drilling operation.
