    Abstract: A process for the concentration by flotation of gold, gold bearing minerals and uranium oxide minerals from ores and metallurgical plant products whereby a pulp of a ground ore is agitation conditioned in at least two agitation conditioning stages wherein in at least one stage the pH of the pulp is lowered with an acid agent to within the pH range of about 1.5 to 5.0, and wherein in at least one additional agitation conditioning stage the pH of the pulp is raised to within the pH range of about 6.0 to 11.0 and wherein in at least the last stage prior to flotation at least one collector selected from the group of sulfhydryl anionic collectors is present, and subsequently, the at least two stage agitation conditoned pulp is subjected to flotation to produce a flotation concentrate enriched in at least one of the mineral values from the group consisting of gold, gold bearing minerals and uranium minerals.

    Abstract: An improved method in concentration of oxide ores and minerals by froth flotation process which comprises subjecting a pulp of mineral slurry to the combined action of a organic nitrogen compound with one or more NH.sub.2 group and hypochlorite in a slightly acid pulp of mineral slurry. The decomposition of the NH.sub.2 group provokes a highly oxidizing state in the mineral slurry, a state which can change the valency state of any metal which can change the valency state from lower to higher of the metal at the mineral surface, thus rendering the mineral particle to be capable of activating the double carbon to carbon bonds of certain collectors possessing these bonds as are olefine alcohols or olefine glycols. The indicated compounds provide recovery of oxide minerals of iron, antimony, cerium, yttrium titanium and thorium, vanadium, niobium, tantalum, chromium, and wolfram.
