The mechanism on reducing manganese oxide ore with elemental
The raw material used in this study was low-grade manganese clay with a grade of 6.1% Mn, and the main manganese mineral was pyrolusite. FeCl 2 4H 2 O and a dilute hydrochloric acid solution were selected as the most effective reductant and solvent, and the leaching efficiency of manganese and iron was greater than 92% and 70%, High concentrations of manganese (Mn 2+) and ammonia nitrogen (NH 4 +-N) in electrolytic manganese residue leachate (EMRL) have seriously polluted the environment.In this study, electric field and phosphorus ore flotation tailings (POFTs) were used for Mn 2+ and NH 4 +-N removal in EMRL firstly.The effects of the liquid acid ratios, A green method for Mn2+ and NH4+-N removal in electrolytic manganese

Removal of sodium oleate from synthetic manganese
The coagulation-dissolved air flotation for removal of sodium oleate (NaOL) from synthetic manganese leaching solution was focused in this study. It indicates that partially hydrolyzed polyacrylamide (HPAM), NaOL dosage and pH have a multiple effect on the removal efficiency of NaOL.Flotation has previously been studied in the context of manganese oxide ore beneficiation (Fuerstenau et al. 1986). It is generally observed that flotation of oxide minerals can upgrade the ore byReagents used in flotation experiments Download Table

On using electrokinetics to interpret the flotation and
Sodium oleate is also widely used for manganese ore flotation (Zhou et al., 2015). Electrokinetic analyses were used to interpret the flotation and interfacial behavior of manganese dioxide with NaOL as collector (Fuerstenau and Shibata, 1999). However, a large dosage of NaOL is required when it is employed in the flotation of manganese oresIntroduction. Manganese is an important metal with wide industrial applications in many aspects of social economy. Approximately 90–95% of manganese are consumed in the steel production, and the rest are used in the fields of non-ferrous production, battery, and dietary additives (Tan et al., 2004, Mei et al., 2011, IMnI, Extraction and separation of manganese and iron from

Materials Free Full-Text Study of the Effect of Manganese
The flotation separation (FS) of both scheelite and calcite minerals with similar physicochemical properties remains challenging, since the Ca active sites exist on their surfaces. The present work investigated the effects of different addition points of MnCl2 on the FS of scheelite and calcite by micro-flotation tests, zeta potential measurements, The flotation of manganese ore can use positive flotation and reverse flotation. At present, anion-positive flotation is widely used, and cation reverse flotation is still in the experimental stage. Since manganese ore is mostly carbonate and oxidized minerals, whose surfaces are easily wetted by water, their flotation performance is poor.

The flotation test revealed that scheelite recovery increases gradually with increasing manganese chloride following manganese chloride addition, while the recovery of calcite gradually decreases. The recovery difference between the two minerals reached 82.84% points, achieving a better separation of scheelite and calcite.王晖,wanghui,中南大学王晖，博士生导师王晖,Wang Hui 王晖，男，汉族，1968 年 2 月生，安徽太湖人，工学博士，中南大学教授，博士生导师，二次资源与环境污染控制研究所所长。 主要从事资源加工、环境化工等领域的研究与教学工作。主持和参加国 中南大学 王晖
