magnesium ore flotation process

The direct froth flotation process is to grind the phosphate ore until the minerals among the ore are dissociated after one stage grinding, suppress the gangue minerals by adding inhibitors, and then add the collector to enrich the phosphate minerals in the foam. This process must be combined with strong inhibitors to obtain best effect

    Langbeinite and kieserite are beneficiated in a flotation process in which separation of ore particles is conducted in a froth flotation process with a magnesium chloride brine containing at least 20 moles MgCl 2 per 1000 mols H 2 O. Said brine is maintained at a pH below about 3.5. The preferred flotation agent is a combination of a fatty acid amine (preferably tallow amine) and an organic acid, either oleic or …

  • the future for flotation e mj

    Velgaard: As implied in the question, in fact flotation chemicals are only one facet of the ‘flotation system,’ where ore conditions, mineralogies, process-system as-pects, how the process is operated, and other factors, define the process capabilities. There are plenty of opportunities for improved flotation performance; we consider the
