The invention discloses a collophane reverse flotation collector and a preparation method thereof the collector is prepared from by mass 3040 of mixed fatty acid 0515 of polyoxyethylene fatty alcohol sodium sulfate and the balance water the preparation method includes the following steps that all the components of the collophane reverse flotation collector are evenly mixed according
Flotation frothers what is the function of frothers the function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic this is used in mineral processing paper recycling and wastewater treatment industries historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century
With regard to a deepextend oxidized refractory leadzinc ore from yunnan province containing 455 pb and 1709 zn a test study was carried out by adopting singlestage roughing singlestage scavenging twostage cleaning in the flotation of lead oxide ores and singlestage cleaning singlestage cleaning in the reverse flotation of zinc oxide ores bulk concentrate of lead and zinc
