    摘要： The invention refers to a process to separate silicates and alkaline earth metal carbonates implementing at least one hydrophobically modified polyalkyleneimine, wherein: i) the polyalkyleneimine is hydrophobically modified by replacement of all or part of the hydrogens of their primary and/or secondary amino groups by functional group R, where R comprises a linear or branched or cyclic alkyl and/or aryl group and contains 1 to 32 carbon atoms; ii) prior to modification, the polyalkyleneimine has at least 3 alkyleneimine repeat units and a molecular weight of between 140 and 100 000 g/mol; iii) modification of the polyalkyleneimine results in an increase in the atomic C amount, relative to the unmodified polyalkyleneimine, of between 1 and 80%. The invention additionally refers to a silicate-containing product and an alkaline earth metal carbonate-containing product obtained by the process of the invention, and to their uses.

    摘要： Fine coals suspended in a coal flotation froth are more efficiently filtered when the flotation froth is subjected to a thickening operation prior to filtration. The thickening operation is accomplished by the use of a clarifier or thickener.

    摘要： A method for dewatering froth fines obtained during the separation of coal, in which a discontinuously operating sieve scraping centrifuge is filled with the froth fines, the mixture is centrifuged at a low rotational speed to remove a major portion of the liquid and to deposit a layer of solid material which acts as a filter aid, and the remaining mixture is then centrifuged at a high rotational speed. The first run-off is reintroduced into the centrifuge to reduce its high solids content.

    摘要： An improved method of separating minerals from phosphate ores is described. The addition of silica depressants to flotation slurries substantially increases the efficiency of mineral separation and thereby reduces the number of flotation steps required to obtain a good yield of ore having the desired mineral concentration.

    摘要： DISCLOSED HEREIN IS A PROCESS TO REDUCE THE AMOUNT OF SOLIDS IN A SECONDARY FROTH TO A LEVEL WHICH IS ECONONICAL BY SUBJECTING THE SECONDARY FROTH TO A WATER WASHING OPRATION WHEREIN THE FROTH IS DEAERATED, COLLAPSED AND SUBJECTED TO INTIMATE CONTACTING WITH FRESH HOT WATER. THE CONTACTING CAUSES THE BITUMEN CONTAINED WITHIN THE FROTH TO ALLOW THE RELEASE OF THE SOLIDS EN-

    摘要： Lubricant-grade molybdenite is produced from byproduct molybdenite flotation concentrates of porphyry copper ores by a sequence of purification steps which include controlled grinding to liberate contaminant minerals and to flatten the molybdenite, followed by a flotation step for the selective recovery of the so-flattened molybdenite. The grinding is controlled to soften impact and minimize duration of the grinding period.
