Producing concentrates from spodumene ores with the highest possible grade of lithium is an important goal to increase the efficiency of the use lithium ores in the framework of sustainability. Participating in Brazilian society project, Fundação Gorceix, through its Mining and Metallurgy Department carried out initial characterization of lithium ores, carried out bench test works in laboratory and pilot plants using a sample provided by the company.  As a result, it was possible to obtain concentrates with a high grade of lithium, above 5,7%, (target 6,0%) compatible with market demand. The subsequent work included the simplification and proposition of the new industrial process flowsheet (flotation of micas/feldspathe has been excluded). This paper will present this work and the results achieved.
