Chemical processing of dolomite associated with the

2015-12-27 The chemical analysis of New-Valley dolomite ore is given in Table 1. It is clear that, the theoretical MgO content in pure dolomite mineral is 21.875%, this indicates that, the purity of dolomite ore is about 75.66%. The ore contains a high amount of calcium oxide which causes the problems after solid/liquid separation due to high content of produced calcium sulfate dehydrate. In addition, the ore contains a high amount of carbon dioxide, which causes excessive foams during the acid leaching process and consequently decreases the effective capacity of the reactor. In industry, the process can control by increasing retention time, calcinations of the ore

Flow, dissolution, and precipitation in dolomite

dissolution of dolomite is a (slow) reaction rate limited process at room temperature [Lund et al., 1973]. The main aim of the current experimental research is to understand the evolution of hydraulic conductivity and flow patterns, caused by concurrent dissolution of dolomite and precipi-tation of calcium carbonate, in porous dolomite rocks. In

Effect and mechanism of phosphoric acid in the apatite

2017-10-10 To elucidate how phosphoric acid (H 3 PO 4) as a depressant achieves selective separation of apatite and dolomite, the flotation response of these minerals was investigated using both single and mixed mineral flotation.Microflotation results demonstrated that H 3 PO 4 exhibits a selective depressive effect on apatite. Flotation kinetics analyses also revealed that the presence of H 3 PO 4
