    Abstract: The invention is related to a flotation process using an improved collector to remove alkaline earth metal carbonate impurities from phosphate ores. The flotation feed may be conditioned with the improved carbonate collector at acidic pH, and subjected to a reverse flotation. The cell overflow may be collected as waste in which carbonate minerals dominate, and the cell underflow may be the phosphate concentrate. The collector may be a combination of chemicals, comprising: (1) any kind of fatty acids, either conventional fatty acid, saponified fatty acid, or modified fatty acid; (2) chemicals with sulfonate or sulfate groups, such as dodecylbenzene sulfonic acid (DDBSA) or its salt, sodium dodecyl sulfate (SDS), sodium lauryl sulfate (SLS), sodium coco sulfate (SCS), etc.; and (3) phosphorous-bearing chemicals, such as sodium tripolyphosphate (STPP), sodium hexametaphosphate (SFMP), trisodium phosphate (TSP), Tetrasodiumpyrophosphate (TSPP), etc. With the improved collector, the separation selectivity and phosphate recovery may be significantly improved.

    Abstract: A flotation method for mineral processing is disclosed. The method for floating includes a first step of using a first carboxymethyl cellulose (CMC) in a first flotation cell, and a subsequent step includes using a second CMC in a subsequent flotation cell, the first and second CMCs having different characteristics. The first flotation cell may be used in at least one rougher stage and/or at least one rougher-scavenger stage of the flotation method, and the subsequent flotation cell may be used in at least one cleaner stage, and/or at least one cleaner scavenger stage, and/or at least one recleaner stage of the flotation method. A product may be obtained, directly or indirectly, by such a method. A mineral processing plant may use at least two CMCs of different characteristics in flotation for mineral processing.
