    Abstract: Froth flotation of oxidized coal in the presence of certain imidazoline or imidazolinium salts improves both the selectivity and recovery attained. Imidazolines found particularly efficacious are those bearing a fatty alkyl group in the 2- position and an N-aminoethyl or N-hydroxyethyl group. Preferred imidazolinium salts are those corresponding to the following formula: ##STR1## wherein R is a C.sub.6 to C.sub.22 alkyl or alkenyl group.

    Abstract: A method for upgrading the bitumen content of tar sands, wherein a raw tar sand slurry admixture of tar sands, water, collectors, and dispersing/wetting agents is milled; conditioned and then separated by a series of froth flotations at ambient temperatures from about 2.degree. C. to about 25.degree. C. to recover a concentrated bitumen tar sand product which may be processed by conventional means to recover oil from the bitumen. Enhanced recovery of bitumen may be accomplished by moderate heating in one or more of the flotation zones to about 50.degree. C. The method permits recovery and recycle of various components used in processing of the tar sand.

    Abstract: A process for the separate recovery of phosphate and carbonate minerals from finely-divided phosphate-carbonate-silicate ores or concentrates with a carbonate to phosphate ratio of over 1 is disclosed, in which an anionic collector agent is added to an aqueous slurry of these ores and concentrates, the slurry is then exposed to froth-flotation in order to separate a silicate-bearing residue from phosphate-carbonate concentrate, thereafter(a) the combined phosphate-carbonate concentrate is either treated with a base in order to remove the collector-agent coatings from the surfaces of the mineral particles, whereafter the combined concentrate is froth-flotated with a cationic collector agent using a depressing agent for carbonate in order to recover the phosphate concentrate and the carbonate concentrate separately, or(b) the aqueous slurry to which the anionic collector agent has been added and which has been froth-flotated is treated with sulfur dioxide or carbon dioxide in order to inactivate the collector-agent coatings on the surfaces of the carbonate minerals, whereafter the slurry is froth-flotated in order to obtain separately recovery of a phosphate concentrate and a carbonate concentrate.

    Abstract: An improvement is provided in a process for the flotation of an acid grade fluorspar enriched concentrate, having a sulfide sulfur content not greater than about 0.02%, from a fluorspar ore containing in addition to fluorspar substantial amounts of gangue minerals and metallic sulfide accessory minerals. The invention utilizes in this conventional flotation process an alkali metal sulfide, preferably sodium sulfide, as a depressor reagent, in substitution of environmentally objectionable sodium cyanide, to depress the flotation of metallic sulfide minerals, thereby rendering a flotation concentrate low in sulfide sulfur content while substantially reducing associated environmental effects.

    Abstract: Process using collectors for the flotation of minerals which allow the separation or enrichment of certain minerals, even at pH values around 7. These collectors are organic sulphides of the type R--S--R', in which the two groups R and R' are different and at least one of them preferably carries a substituent including oxygen or sulphur. The collectors are desirably used in a proportion of 10-100 ppm in relation to the weight of the mineral subject to flotation.

    Abstract: A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell, is dried to produce a manganese concentrate, and is sintered to produce a synthetic manganese oxide. Sintering of such concentrates at 1000.degree. C. yields a product containing greater than 50% manganese.The effect of reagent dosage, pH control, and temperature control on the yield of the synthetic manganese oxide is also disclosed.
