A Review of Flotation Separation of Mg Carbonates
It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite.analysis of the crushed ore was carried out on a photometric sedimentometer (FSKh-6K). Flotation was carried out on a laboratory flotation machine with 0.5, 0.75, 1.0 and 1.5 L chambers. The collective copper–molybdenum flotation cycle included basic flotation, control flotationand three concentrate purifications.

Improving the Copper-Molybdenum Ores Flotation Technology
Technological equipment was also used. The original ore was crushed on a jaw crusher (DMD160/100) to a coarseness of less than 2.5 mm at Bishkek Experimental and Experimental Plant of Geological Exploration Equipment. Then the ore was crushed in a ball mill (40ML-000PS) to a particle size of 94% of the class of less than 74 m.

Surface Electrical Behaviors of Apatite, Dolomite, Quartz, and
The phosphate ore flotation is achieved through the surface electrical behavior difference among apatite, dolomite and quartz, but it is usually affected by the dissolved ions from pulp, especially Ca2+ and Mg2+. The zeta potentials of apatite, dolomite, quartz, and phosphate ore in different solutions were measured to discuss the surface electrical It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite.

Molybdenum
Molybdenum. body-centered cubic (bcc) Molybdenum is a chemical element; it has symbol Mo (from Neo-Latin molybdaenum) and atomic number 42. The name derived from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. [7]Abstract. Molybdenum is an important alloy element for metallurgical industry because of its high temperature stability. As the major mineral reserve for molybdenum, molybdenite (MoS 2) is commonly found in porphyry copper deposits. Molybdenite is naturally floatable and can be separated from copper sulfide mineral using Recent progress on research of molybdenite flotation: A review

Aerosol flotation of low-grade refractory molybdenum ores
Compared with conventional flotation in which kerosene was directly added into the ore pulp, the flotation time was reduced by ~30%, and the dosage was decreased by ~20% in aerosol flotation, while the Mo flotation index was similar. Keywords: molybdenum ore treatment; flotation; kerosene; aerosols; particle size 1. IntroductionThe way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. The conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties.
