Characteristics and controlling factors of dolomite karst reservoirs of the Sinian Dengying Formation, central Sichuan Basin, southwestern China

Precambrian Research, 2020
The Sichuan Basin is a typical superimposed oil- and gas-bearing basin with abundant hydrocarbon resources in deeply buried marine carbonate rocks. The petrological characteristics, origin, diagenetic evolution and controlling factors of the high-quality

Selective co-adsorption of a novel mixed collector onto magnesite surface to improve the flotation separation of magnesite from dolomite

Powder Technology, 2020
It is difficult to effectively separate magnesite from dolomite owing to the similarity of their surface properties. In this study, a novel mixed collector of oleic acid and dodecyl phosphate was used to increase the flotation difference between ...

Epigenetic dolomitization and the origin of xenotopic dolomite texture

Journal of Sedimentary Research, 1984
Abstract Xenotopic texture, which is commonly observed in pre-Cenozoic rocks, is defined here as a mosaic of anhedral crystals with irregular or curved intercrystalline boundaries and, usually, undulatory extinction. Xenotopic dolomite texture is similar in appearance to neomorphic limestone textures.

Dolomite-dolomite separation by a selective flocculation technique

Mining, Metallurgy & Exploration, 1995
The viability of physico-chemical purification methods such as selective flocculation for the separation of two components having similar chemical compositions and the same crystal structure but different surface properties is demonstrated. A loss of selectivity was observed in a dolomite-dolomite mixture when polyethylene oxide (PEO) (five million ...

Study of using dolomite ores as raw materials to produce magnesium phosphate cement

, 2020
Although magnesium phosphate cement (MPC) is a type of chemically bonded ceramic with many vital properties, the practical application is limited by the high cost of raw materials.

Fluidization characteristics of dolomite and calcined dolomite particles

Chemical Engineering Science, 2000
Abstract Experimental measurements were performed of the minimum fluidization velocities and the terminal velocities of a bed of dolomite and its calcine. Using air, experiments were conducted in an 8.5 cm i.d. column with very narrow fractions of particles in a range of 0.14– 0.72 mm .

Behaviour of GGBS-dolomite geopolymer concrete short column under axial loading

, 2020
Geopolymer concrete was developed from Ground Granulated Blast furnace Slag (GGBS) and dolomite which are obtained from steel and rock industries. Optimum proportions of GGBS and dolomite were found out based on the maximum compressive strength.

Optical, structural and gamma ray shielding properties of dolomite doped lithium borate glasses for radiation shielding applications

, 2020
The elemental analysis of dolomite [CaMg(CO3)] doped glasses encoded DG10, DG20, DG30 and DG40 with different compositions is tested using Energy Dispersive X-ray (EDX) technique.
