4/4/2020· as a fundamental process for calcium and magnesium separation process in dolomite. SEM-EDX and XRD analysis proved that partial calcinations at 675°C for 6 hours is able to produce magnesium oxide (MgO) and calcium oxide (CaO). Then sea water was added to calcinations product so magnesium hydroxide and calcium carbonate that easily separated by sea water. TheCited by: 1

Elimination of the Adverse Effect of Calcium Ion on the

The separation of magnesite from dolomite was studied by flotation tests, X-ray photoelectron spectroscopy (XPS), and zeta potential measurements in the presence of calcium ion (Ca2+) dissolved from dolomite. Sodium oleate (NaOL) was used as collector, and sodium carbonate (Na2CO3) and sodium hexametaphosphate (SH) were used as regulators.Cited by: 26

Dolomite – Virtual Museum of Molecules and Minerals

Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites. Most dolomite samples contain only a few percent of substitution of calcium for magnesium, and vice versa.

Dolomite - an overview | ScienceDirect Topics

However, usage of sucrose solution to separate these components from dolomite has been proven to be an exceptionally successful method [93]. When calcined dolomite (CaO⋅MgO) is dissolved in a sucrose solution, CaO will be converted into soluble calcium sucrate [94] , while MgO remains unreacted and presents in …

Dolomite and Magnesite with Reference to the Separation of

*Richards developed a method for the separation of calcium and magnesium where the substances are somewhat equal in amount, as in dolomite, and his method differs in some important particulars from those commonly employed. To the soluti-on of calcium and magnesium chlorides, Richards adds

9/5/2018· A process to prepare a mildly aklaline mineral product by calcining the dolomite under conditions to convert only the MgCO.sub.3 to MgO and treating the selectively calcined dolomite with acidic solutions to dissolve largely the MgO, leaving the original CaCO.sub.3 matrix intact.
