The results of the technical and mineralogical studies of washability of low quality bauxites of North Onega deposit are presented. The experiments of determination of the grindability of raw materials including without ball grinding and assessment washability bauxite  by magnetic separation and flotation were conducted. These ores are very complex object for enrichment, as characterized by extremely thin impregnated aluminum-containing minerals, as well as  the similarity of their properties. Further work of to conduct experiments using chemical enrichment (as soon as the chemical enrichment, and in combination with the physical methods of enrichment) is planned.
