Jan 15, 2019 In many lithium ore beneficiation plants, it is a common practice to de slime the ore prior to flotation. De sliming is typically carried out to remove the −20 m size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de sliming is.Breakage function for HPGR Mineral and mechanical characterization oftantalum and tungsten ores published pages , ISSN 2075 163X, DOI Minerals 2019 05 29 2017 Kupka N. and Rudolph M Comparing existing froth flotation models in a case study of a scheelite ore published pages , ISSN , DOI FIA Tagung November 2017 2019 05 29 2017.
