Calcite-Apatite Flotation - Columbia University. flotation is to depress the flotation markedly in the neutral to alkaline pH (pH . 13) range.. A comparison of the effects of added inorganics with those of the supernatants suggests that the depressing effect of apatite supernatant is the combined effect of,calcium and phosphate species in solution. Flotation of calcite at pH 9.7 Semisoluble Salt Flotation Apaptite (calcium phosphate) is one of the major non-metallic minerals produced by flotation The pzc is 6.4 yet as shown below the flotation response with oleate extends well below this pH indicating chemisorption. Flotation of apatite with 1x10-4M oleate with/without silicate addition Semisoluble Salt Flotation Rock phosphate contains

depression. Silica, feldspar, calcite, phosphates. Flotation of Insoluble Oxides and Silicates: There is a very large number of minerals of this type. Whether or not they float depends on - Electrical properties of the mineral surface - Charge of the collector - Molecular weight of the collector - Solubility of the mineral - Stability of the collector/metal salt Depending on these properties

Selective depression of the sulfide minerals could not be achieved by raising pulp pH. 2. Both thioglycollic acid and citric acid selectively depressed the sodium oleate flotation of pyrite between pH 9.0 and 10.5 without affecting the flotation of calcite and dolomite. However, neither acid could depress chalcopyrite. 3. Cited by: 17; Calcite Wikipedia. Calcite is a carbonate mineral and the


Reverse flotation Depression of phosphate: This method was used when the apatite was more abundant than calcite and dolomite (as in most phosphate ore). Among depressants used are as follow: Fluosilicic acid: USBM investigated the removal of carbonate from phosphate rock using fluosilicic acid as a depressing agent and tall oil-fatty acid as a collector for carbonate mineral flotation (Figure

Direct Flotation The flotation separation of Mg carbonates from non-salt type minerals (hematite, gold-bearing sulfides, and monazite) is typically less difficult as compared to their separation from other salt-type minerals (phosphate) [8,10,14,17,18,34,49]. As they are the major gangue minerals of phosphate ore, an effective method of separating them from phosphate minerals is direct
