Abstract: A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing. The depressant consists of a cross-linked starch chemically combined with a polyacrylate and sugar free lignin sulphonate.

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.

Abstract: A method for separating copper sulphides from lead sulphides contained in particulate copper lead sulphide concentrates by a flotation process in which an aqueous alkali metal silicate-alkali metal dichromate reagent solution is added in the flotation step to depress the lead bearing sulphides. The copper lead sulphide concentrate may be obtained from a complex copper-lead-zinc ore, in which case the majority of the zinc is first removed by conventional flotation techniques and the copper lead sulphide concentrate treated with activated carbon prior to addition of the silicate-dichromate reagent solution.
