Abstract

186,760. Vivian, A. C. Aug. 5, 1921. Treating ores to facilitate concentration.-Ores containing the more valuable metals as oxygenccntaining compounds, for instance oxides or carbonates, are concentrated by a flotation process which consists in adding to the ore organic compounds, which are generally considered weakly acid but are amphoteric or display acipseudo forms, contain nitrogen and oxygen, and act upon the metals or metal compounds it is desired to concentrate forming tarry or resinous complexes or decomposition products under the conditions which commonlv occur in flotation processes, with or without the use of known oiling or frothing agents. In some cases this action is assisted by the presence of an oxidising agent, which may be the oxygen of the air used for frothing. Examples of these organic compounds, which may be added to or formed in the presence of the ore to be concentrated, are cupferron, oximes, iso-nitroso bodies, amido acids such as taurocholic acid, phenyl glyoxime, dinitroso resorcinol. The organic compound may also be formed by the reaction between ketones or aldehydes and hydroxylamine, nitrous oxide, or ammonia.
