Settling and Filtration Tests on the Acid Grade Concentrate from a Mixed Fluorspar Sample from Dungarpur, Rajasthan

Abstract

In connection with a Techno-Economic Appraisal of the Rajasthan Fluorite project prepared by M/S WRIGHT ENGINEERS Ltd.’’ of Canada, the Director of Mines &Geology, Government of Rajasthan Desired that Settling and filtration tests should be done at the National Metallurgical Laboratory on the acid grade flotation Concentrate that will be produced in the proposed flotation plant to determine the size of thickener and vacuum filter. The work involves (1)mixing of three samples in proportion (2:1:1), (II)grinding the mixed sample to 87% -200 mesh for flotation of fluorspar, and (III)regrinding of rougher float to 92%-325 mesh and reflotation of some produce that final concentrate for settling and filtration tests.
