Picking of ore

The ore dressing method of strontium ore is utilized due to the large number of minerals, hand selection, re-election (including heavy medium dressing), flotation, and separation flotation. The hand selection of strontium ore is based on the difference in color and gloss shape of strontium-bearing minerals and gangue minerals in strontium ore.
