Pulp pH value plays a significant role in the froth flotation. Especially in the flotation of fluorite, the performance of flotation will be affected greatly by pulp pH. MO, a new kind of modified fatty acid was used as collector, and H2SO4 and Na2CO3 were used to regulate pulp pH in the experiment. The mechanism of influence of pulp pH on flotation of fluorite and calcite was investigated by ...

The Problem with Calcite Processing & Flotation The availability of high lime rock is often limited and it becomes necessary to use lower grade sources from quarries favorably located to cement plants. Beneficiation of the lime rock in such cases is necessary to remove impurities and to secure the proper ratio of calcite to other constituents for cement specifications.

Calcite-Apatite Flotation - Columbia University. Calcite flotation The results obtained for the pH dependence of flotation of calcite using 10 -4 kmol/m 3 potassium oleate at two levels of pH. Interestingly, flotation at the minimum is found to increase from about 25% to 85% with increase in KNO3 from 0 to 3 x 10-2 kmo1/m3.
Flotation of calcite/apatite mixtures Results obtained for the flotation of calcite/apatite mixtures as a function of alizarin red S concentration are given in Fig. 7. In the absence of alizarin red S modifier, oleate floats both minerals at close to levels. As alizarin red S concentration is increased to 5 X 10-6 kmol/m3, the flotation of ...

Flotation recovery of vanadium from low-grade stone coal ... Two-stage flotation experiments were carried out using combination of reverse and direct flotation. Calcite was primarily floated to avoid negative effect on the subsequent flotation of vanadium-bearing minerals, and then the tailing from calcite flotation was further subjected to ...
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 non-floatable 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.

CalciteApatite Flotation Columbia University. The effect of calcite supernatant on its own flotation is also to depress it significantly in this pH range (see Figure 3) Thus, while both the supernatants of calcite and apatite depress calcite flotation under s~ilar pH conditions, their effect is minimal above pH 13.

Selective separation of calcite from a binary mixture with hematite was carried out after interaction with bacterial cells. Interaction of mineral mixture with bacterial cells resulted in 74 per cent flotation recovery of calcite and 15 per cent for hematite.
representing flotation kinetics may be expressed as dC --= -kC" (1) dt where C is the concentration of solids, t the flotation time, n the order of the process and k the flotation rate constant. A series of experiments were performed to study flotation kinetics for celestite, under the follow-
Back to Rocks and Minerals Articles Kelly Snyder and Peter Russell Calcite: A mineral consisting largely of calcium carbonate (CaCO3 ). Next to quartz, it is the most abundant of the Earth's minerals. Crystallizing in the hexagonal system, calcite is noted for its wide variety of crystalline forms.
flotation of calcite stone [.–Ratings ] The Gulin product line, consisting of more thanmachines, sets the standard for our industry. . Calcite flotation in acidic media is a difficult task due to the solubility of calcite and consequently the release of calcium ions in the flotation pulp.
Flotation again increases to about around pH 13. The effect of apatite supernatant on oleate flotation of calcite at both levels of KNO3 is to depress the flotation marked-ly in the pH region of 6 to 12.5 (see Figure 2). Most interesting-the effect of calcite supernatant on its own flotation is
