Jan 01, 2021 · As a result, the aggregates retain gas bubbles that originated in the respiration process and become less dense than the wine (Zara et al., 2021). Initially, the molecular basis for cell surface hydrophobicity during flor formation has been attributed to an elevated unsaturation level and mean chain length of fatty acid residues in membranes

However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals. Outside this range, the efficiency of froth flotation decreases significantly,

Review of Potential Microbial Effects on Flotation

Flotation is the most common method for concentrating ore, and it is based on the separation of hydrophobic materials from hydrophilic ones [] in an extremely complicated dynamic process including interactions of gas, liquid, and solid phases under flow.Much of the research has focused on electrostatic, van der Waals, hydrophobic, and capillary interactions, but there are

A strategy to accelerate the bioleaching of chalcopyrite

Theoretically, controlling redox potential to a relatively low value and inhibiting jarosite formation on the chalcopyrite surface would be an effective strategy to accelerate the bioleaching of chalcopyrite. In this work, using limonite as seed crystals, the effects of the goethite precipitation process on the bioleaching of chalcopyrite were studied for the first time.
