    Abstract: A new depressant composition is provided for the enhanced separation into separate value metal concentrates of copper, nickel, zinc, lead present in polymetallic and massive sulphide ores.The depressant is added in an aqueous solution prepared by dissolving first a mixture of quebracho and dextrin, or quebracho and guar gum. To the solution of modified quebracho a water soluble salt of lignin sulphonate is added. The aqueous polymer of modified quebracho lighin sulphonate is further mixed with one or more of the following inorganic reagents: water soluble cyanide, metal sulphates and water soluble sulphites. The resulting depressant is added together with conventional flotation reagents in conventional mineral separation stages as required.

    Abstract: A process is described for the mineral separation of rare earth metal compounds, such as bastnaesite, contained in oxidic minerals. The process is a froth flotation process utilizing a novel collector emulsion, which is an emulsified mixture of:a secondary amine modified sulphonated fatty acid,a high rosin containing tall oil fatty acid,an anionic petroleum sulphonate, anda high molecular weight primary amine.The collector emulsion mixture is added to the aqueous slurry of the comminuted rare earth metal compound containing oxidic mineral, which has been previously conditioned in a conventional manner. The conditioning reagents may include alkaline pH modifiers and gangue depressants such as citric acid, oxalic acid, sodium silicates and fatty acids.The rare earth metal compounds will be concentrated in the froth, and are separated in the conventional manner.
