Abstract: A process for improving the efficiency of coal dewatering and deashing uses complexing agents such as sodium gluconate in alkaline solution to form soluble compounds with cations such as Al.sup.+3, Fe.sup.+3, Mg.sup.+2, and Ca.sup.+2. The formation of such compounds reduces the adsorption and/or desorbs clay slimes from the coal surface.

Abstract: A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.

Abstract: The invention resides in the use of a bacterial cellulose as a depressant for readily flotatable silicate minerals in an ore flotation process. Depending on the particular ore being treated, from 0.2-1.5 lb/ton of ore of the bacterial cellulose is effective as a talcose mineral depressant. Usually only about 0.10-0.25 lb/ton of the bacterial cellulose will produce optimum results.

Abstract: Disclosed is an improved froth flotation process wherein solid coal particles are selectively separated under coal froth flotation conditions as a froth phase from remaining solid feed particles as an aqueous phase in the presence of a coal particle collector (e.g. a fuel oil), optionally a promoter, and an alcohol frother. The improvement in the present invention is characterized by the alcohol frother comprising the reaction product of a C.sub.4 -C.sub.10 diol and a compound selected from the group consisting of an alkylene oxide and an acrylonitrile. The resulting frothing agent has at least one hydroxyl group and provides greater coal recovery than use of the diol as the frothing agent.

Abstract: Process of flotation of minerals, which consists of introducing the flotation collector into the mineral pulp to be treated in the form of a microemulsifiable composition. In general, the collector agents are organic compounds containing sulphur, particularly mercaptans, thioethers or polysulphides, which generally are very slightly soluble in water. This process is particularly suitable for minerals based on oxides and sulphides.
