Six steps to process iron ore 1 Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage A static screen is used to divert the fine particles for crushing This step prevents overloading the crusher and increases its efficiencyA typical run of mine ore can contain 12% Li2O, while a typical spodumene concentrate suitable for lithium carbonate production contains 67% Li2O (75% 87% spodumene) Higher grade concentrates with 76% Li2O and low iron content are used in ceramics and more demanding industries MINERALOGICAL ANALYSIS OF A TYPICAL PEGMATITEHard Rock Lithium Processing SGS
