Abstract

Process and apparatus for recovery by foam flotation of minerals from ores and products of metallurgical plants containing at least one sulfide mineral, the process being characterized in that it comprises: subjecting a duly prepared paste of the material to treatment in at least one agitation treatment circuit consisting of at least one treatment step by alkaline stirring and wherein in the said treatment step by alkaline stirring the treatment is carried out in the presence of an alkaline agent selected from the group consisting of lime, calcium hydroxide, hydroxide sodium carbonate, sodium carbonate and ammonium hydroxide and where the ph of the pulp is at an optimum ph point within the range of about 8.0 to 12.0 and where at least in the final agitation treatment phase before the flotation is present a sufficient concentrate of collector chosen from the group of anionic sulphide collectors drilo and, when the ore is a molybdenum sulphide, fuel oil is also present, and where said pulp is subjected to agitation treatment with sufficient energy consumption per tm. Of material treated in said phase by at least treatment by alkaline stirring and during a sufficiently long period of residence time of the material in said treatment step by alkaline stirring to produce a charged activation of said sulfide mineral; subsequently, in the presence of an appropriate foamer, said foam-floatable pulp is produced to produce at least one flotation concentrate enriched in said sulphide mineral and a depleted gangue of said sulfide mineral.
