Abstract

An aliphatic mono-carboxylic acid diester of the formula R1.COO.R.OOC.R2 is added to mineral pulp as a frothing agent: R is saturated hydrocarbon or oxahydrocarbon chain which may bear alkyl, alkoxy or alkoxy-alkyl substituents and contains 2-10 carbon atoms, and R1 and R2 are alkyl or alkoxyalkyl groups, the same or different, and each contain 1-19 carbon atoms. Such ester contains a small number of, e.g. seven or less, carbon atoms in the R group when this consists mainly of carbon and hydrogen and when R1 and R2 each contain 10-19 carbon atoms. Examples include butane-1 : 3-diol diisobutyrate, pentane-1 : 5 diol diacetate, heptane-1 : 7 diol diacetate, 2-methoxy-methyl-2 : 4-dimethylpentone-1 : 5 diol diacetate, 2-methoxymethyl-2 : 4-dimethylpentane-1 : 5-diol di-(3-methoxypropionate), diethylene glycol diisobutyrate and triethylene glycol diisobutyrate. Other frothing agents may be present e.g. 1 : 1 : 2 : 2-tetraethoxyethane, 1 : 1 : 2 : 2-tetra normal propoxyethane, 1 : 1 : 2 : 2- tetrabutoxyethane, 1 : 1 : 3 : 3-tetranormal propoxypropane, 1 : 1 : 4 : 4-tetramethoxy-butane, and 1 : 1 : 5 : 5-tetraehtoxypentane. Collecting agents such as ethyl xanthate, dithiophosphates, phosphocresylic acids, diphenyl thiouric, fatty acids and fatty acid soaps, may be used. These reagents may be employed in the flotation of copper-containing sulphidic ores or ores of lead, zinc, iron, molybdenum, nickel and gold and coal.
