Abstract
A high grade fraction is recovered from lithium-containing ores by conditioning a finely-ground aqueous pulp of the ore with a conditioning reagent formed by incorporating a water-soluble polyvalent metal salt into an aqueous solution of an alkali metal silicate and with an anionic collector and then subjecting the conditioned pulp, without desliming, to a froth flotation operation whereby a concentrate containing lithium and a tailing containing gangue are produced.
