·For magnesite with the increase of pulp pH the flotation recovery of magnesite increased slowly When the pulp pH risesd to 11 the flotation recovery of magnesite reached % and when the pulp pH continues to rise the flotation recovery of magnesite almost unchanged Therefore the optimal pulp pH was determined to be 11
·The froth flotation tests were carried out using a laboratory XFG self aeration flotation machine which was shown in Fig 1 The volume of the flotation cell is approximately 40 mL Mineral sample weighed g was loaded to the flotation cell For magnesite flotation the collector dosage and slurry pH were set at and 90 mg∙L −1
·Magnesite is often accompanied with dolomite feldspar and quartz [3] Flotation is considered to be one of the most effective ways to purify magnesite [4 5] In the 1930s froth flotation was already employed for magnesite mineral processing by Doerner and Dwigh [6] According to their work it was quite easy to separate silicate minerals
·In order to reduce the iron impurities in magnesite ore and improve the purity of magnesium products the difference in floatability between magnesite and limonite has been studied by using

The new flotation concept RCS 300 The RCS Reactor Cell System flotation machine has been developed to combine the benefits of the circular cell concept with the unique features of the DV mechanism to create the ideal conditions to maximize flotation performance for roughing scavenging and cleaning duties
·1 Introduction Magnesite is a vital feedstock material for magnesium extraction which is applied for the industrial manufacture of magnesium based alloys advanced materials and magnesium bearing chemical reagents [1] [2] [3] [4] Quartz is the main silicate gangue mineral related to magnesite and its presence in the concentrate reduces the product quality
·The feasibility of producing high density sintered magnesia with a one step sintering method was investigated by utilizing finely ground magnesite as raw materials for direct flotation The mechanism of flotation desilication of microfine grain magnesite was investigated by combining microstructure and chemical properties The results showed that dodecylamine
·Machine learning ML an application of artificial intelligence is a powerful tool that has been deployed to simplify complex and timeconsuming operational studies [21 22]
·DOI / Corpus ID 237797531; Role of surface roughness in the magnesite flotation and its mechanism article{Zhu2021RoleOS title={Role of surface roughness in the magnesite flotation and its mechanism} author={Zhanglei Zhu and Ya feng Fu and Wan zhong Yin and Haoran Sun and Keqiang Chen and Yuan Tang and Bin
·Methods for separating magnesite from its primary gangue minerals are chosen depending on the type of ore deposit and ore properties; such separation methods include gravity separation magnetic separation flotation electrostatic separation and chemical separation [7] [8] [9] Because of the extremely poor fine and miscellaneous nature of magnesite ore
The experiment involved a single mineral flotation test using a laboratory XFG self aeration flotation machine Changchun Exploration Machinery Factory Changchun China with the impeller speed fixed at 1992 r/min Five grams of magnesite was added to the flotation tank which contained 35 mL of deionized water
·The influence of pulp temperature on the floatability of magnesite and dolomite were studied by flotation test Inductive Coupled Plasma Emission Spectrometer ICP was used to measure the dissolved metal ion content in the pulp by minerals in solution X ray photoelectron spectroscopy XPS was used to measure the presence and relative content of metal ions on
·The flotation results demonstrate that Na2ATP exhibits a more intense depression on the flotation of dolomite than that of magnesite and can separate effectively magnesite from dolomite which
