For pyrite-serpentine flotation system, pyrite flotation recovery was improved as the increase of OA concentration. As seen, the recovery was 90.12% when OA concentration reached 60 mg/L and remained nearly unchanged as the further increase of OA concentration. Obviously, the above results imply that the detrimental effect of …

In addition, different flow characteristics tend to exhibit unique features. The axial flow field plays significant roles in realizing the particle suspension and showed strong circulation characteristics, while the radial one corresponds to the shear mechanism of fluid flow and is dominant in the dispersion process of flotation reagents [17,18].
This study offered some new insights into the adverse effect of serpentine on sulfide flotation, and the employment of stir medium such as garnet, might be a potential way to improve the flotation ...
Reverse flow = NO. Reverse rotation = Maybe. A V-belt accessory drive will need a regular-rotation water pump. Pulley will spin same direction as crankshaft. A serpentine belt accessory drive where the RIBBED part of the belt is turning the water pump pulley will also require a regular-rotation water pump.

Meanwhile, the fine serpentine (<38 μm) showed a higher recovery in ascharite concentrate (Fig. 2(b)), which further confirmed the interference of fine serpentine was more obvious in the flotation process. 3.2 Influence of SHMP on ascharite flotation To reduce the serpentine interference on ascharite flotation, SHMP was added to the pulp.
1. Introduction. Serpentine (Mg 3 Si 2 O 5 (OH) 4), as a magnesium-rich phyllosilicate mineral, often associates with complex sulfide ores as a gangue component.Flotation is a commonly used method for separating these sulfide minerals and serpentine (Pan et al., 2019).In sulfide ores processing, serpentine breaks easily due …

Following the review, a homo-aggregation flotation (HAF) concept different from conventional approaches is proposed to improve the separation efficiency of fine particles in froth flotation. We present case studies highlighting the necessity of aggregating fine hydrophilic materials to improve separation efficiency in froth flotation, …
In the current research work, the flow behavior of a liquid–liquid extraction (LLE) process in a serpentine microchannel was analyzed. The simulation was performed using a 3D model and the ...
Chlorite and serpentine are common magnesium-containing gangue minerals in copper sulfide flotation. In this study, sodium alginate, a natural hydrophilic polysaccharide, was introduced as a selective depressant for these gangue minerals. Micro-flotation tests were conducted on both single minerals and synthetic mixtures. The …
