    Abstract: A targeted particulate, synthetic organic plastic material having normally hydrophobic surface characteristics is separated from a mixture of two or more of such plastic materials by conditioning the mixture of plastic materials in a flotation cell with a heteropolar surfactant which has a hydrophile-lipophile balance (HLB) value greater than 5 and which selectively depresses the targeted plastic material by making the surfaces thereof more hydrophilic without substantially affecting the surfaces of the other plastic material(s) and introducing gas bubbles into the resulting conditioned pulp such that the gas bubbles selectively adhere to the surfaces of the other plastic materials(s) and cause them to float. The targeted plastic material is recovered in the cell product and the other plastic material(s) is recovered in the float concentrate.

    Abstract: A process for the froth flotation separation of phosphate containing minerals by the use of a new collector agent is described. The new phosphate collector agent is prepared by mixing a fatty acid, tall oil pitch, an amine, and optionally sarcosine with fuel or furnace oil, and subsequently oxidizing the mixture by known methods. The new phosphate collector agent is added to the conditioned slurry of the ground and deslimed phosphate containing ore. The slurry is then subjected to froth flotastion in one or more stages to collect the phosphate concentrate in the froth. The phosphate collector agent is also effective in recovering phosphates from slime.

    Abstract: A process and reagents are described for separating beryllium silicate concentrates by flotation from oxidic minerals. The process is especially suitable for the separation of phenacite and bertrandite present in ores with complex gangue compositions. The ore is ground and subjected to acid pretreatment, then conditioned by the addition of pH modifier, alkali fluoride activator and a depressant containing sodium hexametaphosphate and carboxymethyl cellulose, or hexametaphosphate and quebracho. The conditioned ore is thereafter treated with a tall oil fatty acid-based collector mixture, of general formula C.sub.17 H.sub.31-35 COOH; which also contains cresylic acid, kerosene and a branched short-chained aliphatic alcohol, such as methyl-iso-butyl carbinol. Mercapto acetic acid and alkali metal hydrogen sulphide may also be added in the second and third stages of conditioning, respectively, for increasing selectivity. The mineral concentration process includes conventional rougher and cleaner flotation steps. Yttrium and rare earth oxides, if present will be retained in the tailings.
