Iranian dolomite to produce magnesia doloma (mag-dol) 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. Keywords: Dolomite, Magnesite, Mag-dol, Refractory, Hydration, Corrosion. Technical Note

Abstract. Dolomite [CaMg(CO 3) 2] is an intolerable impurity in phosphate ores, due to its MgO content.The need to develop a cost-effective method for the removal of dolomite from high-MgO phosphate ores becomes increasingly important as high-grade reserves become depleted.

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.

Excessive amount of dolomite also deteriorated the integrity of pellets. AB - High-temperature 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.

Dolomite (/ ˈ d ɒ l ə m aɪ t /) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for .
The problems of enrichment of dolomite, which is used in the preparation of glass batch, are examined. A design of a production line for processing lump dolomite that includes equipment for drying, crushing, and three-step separation of the comminuted material is presented.
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 ca.1010 K and MgO+CaO at ca. 1070 K. Strong antiviral activity was observed after the complete decomposition into ...
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.

The surface features of fluorapatite (FA, Ca5(PO4)3F) and dolomite (CaMg(CO3)2) conditioned with sulfuric acid (H2SO4) were examined through flotation experiments, contact angle tests, time-of-flight secondary ion mass spectrometry (TOF-SIMS), and FTIR experiments. The flotation and contact angle results suggested that oleate insufficiently adsorbed onto the H2SO4-treated FA surface such that ...
