| titleOfInvention | Beneficiation of kieserite and langbeinite from a langbeinite ore |
| abstract | 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 MgCl2 per 1000 mols H2O. 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 sebacic acid, in an approximate ratio of 2 to 4 parts amine to 1 part oleic or sebacic acid, and preferably in an amine-oleic or amine-sebacic acid ratio of about 3:1. Flotation is preferably conducted in two stages wherein the sink product from the rougher flotation contains langbeinite above about 95% concentration which is relatively free of kieserite and the froth from the rougher flotation is passed to a second "cleaner" flotation step where the kieserite is further concentrated to above about 75% kieserite. The sink product from the cleaner flotation is recycled to the rougher flotation step for further processing with the pulp containing the incoming ore particles. |
