Quartz sand flotation purification process | LZZG
The surface dissolution of apatite in the flotation slurry will change the surface properties of the mineral and the chemical environment of the flotation slurry. Generally, quartz sand is easily activated by Ca2+ under alkaline conditions (pH greater than 10), so the dissolved Ca2+ in the apatite solution will adversely affect the separation ...

Design of Special Flotation Equipment for High-Purify Quartz Sand
"As a kind of non-metallic material, high-purify quartz sand has been widely used in many fields. Flotation is a popular way to process quartz sand. But it is in difficult position for flotation to get high-purify quartz product due to large amount of coarse particles contained in the feed. In this paper, a design principle of special flotation cell for high-purify quartz sand has …

Role of mineral flotation technology in improving bitumen …
The role of surface hydrophobicity in water-based oil sand extraction is examined from the perspective of mineral flotation separation. Although anionic carboxylates (sulphonates) released from bitumen are helpful for charging bitumen and liberating bitumen from sand grains, their presence in oil sand slurries tends to make bitumen and bubbles less hydrophobic.

Effect of clays and calcium ions on bitumen extraction from …
A novel approach, based on the doping of rich estuarine oil sands with calcium and/or clays, was developed to study bitumen extraction. The batch flotation tests showed that the addition of either calcium ions up to 40 p.p.m., or kaolinite, illite and montmorillonite clays at 1 wt% of oil sands processed had marginal effect on bitumen recovery from the estuarine ores.
