Enhanced Implications on Turbidity Removal from Natural Stone Wastewater by Binary Mixtures

“…With the decreasing particle size, the surface properties of the mineral particles become more effective in their movement in the solution. As given in the Section of the study, the wastewater mainly contains silicate minerals, and most of the silicates, including those from our previous studies, show negative ζ-potential values over the entire pH range. − So, depending on the magnitude of the ζ-potential values, mineral particles with the same sign repel each other in every direction and suspend in the solution. Their tendency to remain suspended decreases with decreasing ζ-potential magnitude .…”

Improvement Effect of FeSO4·7H2O on Flotation Separation of Scheelite from Fluorite

“…The depressant mixture is a good choice for this specific goal. To enhance the separation efficiency, a mixture of water glass with metal ions (such as Al 3+ , Fe 2+ , Pb 2+ , and Ca 2+ ) have been used in scheelite flotation. − The depressant effect of the joint addition of SS and other salts was first studied by Belash, and a number of studies have since been done. − The original study indicated that these ions could promote the depression capability of water glass in scheelite flotation systems. Oliveira and Sampaio first used FeSO 4 ·7H 2 O as a depressant in scheelite flotation .…”
