Dolomite (CaMg(CO 3) 2) is a critical gangue mineral in most phosphate deposits in China [].The separation of dolomite from apatite determines the success of the phosphate flotation to some extent. Separating dolomite from apatite in an efficient and economically way is difficult for a collophane ore.
Abstract. Dolomite [CaMg(CO 3) 2] is an intolerable impurity in phosphate ores, due to its MgO need to develop a costeffective method for the removal of dolomite from highMgO phosphate ores becomes increasingly important as highgrade reserves become depleted.

Excessive amount of dolomite also deteriorated the integrity of pellets. AB Hightemperature behavior of magnetite—coke composite pellet fluxed with dolomite was investigated by customized thermogravimetric analyzer (TGA) at 1573 K (1300 °C). The overall reaction was influenced by C/O ratio and dolomite content.

The effect of the processing conditions of dolomite powders on the antiviral activity was studied against H5N3 avian influenza virus. When dolomite was fired in the ambient atmosphere, it decomposed into MgO and CaO by two stages at different temperatures, namely into MgO+CaCO3 at K and MgO+CaO at ca. 1070 K. Strong antiviral activity was observed after the complete decomposition into ...

In this work the characteristic of the dolomite powder was carried out due to specifying possible industrial applications. After technological use of dolomite aggregates remaining fine powder becomes waste. Raw and calcined powder samples were subjected to mineralogical, textural and chemical studies involving leaching tests.
Iranian dolomite to produce magnesia doloma (magdol) refractory with high resistance to hydration and corrosion. It was found that addition of 20wt% magnesite to dolomite would result in capsulating of CaO by MgO that protects doloma from further hydration.
