The flotation of fine hematite by selective flocculation using sodium polyacrylate

Kai Cheng et al.

Summary: The study found that the addition of PAAS before NaOL in flotation tests significantly increased the recovery rate of fine hematite, and successfully separated fine hematite from quartz. The findings suggest that the mechanism involves the flocculation of hematite particles by PAAS, which improves floatability and inhibits the adsorption of NaOL on quartz surfaces.

Adsorption behavior and mechanism of copper ions in the sulfidization flotation of malachite

Han Wang et al.

Summary: Pretreatment with an appropriate concentration of copper ions can improve the recovery rate of malachite, while an excessive amount of copper ions reduces the hydrophobicity of the malachite surface. Copper ion pretreatment also promotes sulfidization reactions and the formation of a sulfidization layer on the malachite surface.

Investigations on the reverse flotation of quartz from hematite using carboxymethyl chitosan as a depressant

Hongyang Wang et al.

Summary: Depressant carboxymethyl chitosan (CMCS) was introduced to reverse flotation of quartz from hematite using collector DDA. The reagent scheme of DDA/CMCS could achieve efficient separation of quartz from hematite, with CMCS showing better selective depression ability than starch. Zeta potential measurements illustrated that CMCS could prevent DDA adsorption onto the hematite surface, while it did not affect the interaction between DDA and quartz surface.

Exploration of amino trimethylene phosphonic acid to eliminate the adverse effect of seawater in molybdenite flotation

Guanghua Ai et al.

Summary: The introduction of ATMP chelating agent can mitigate the adverse effects of seawater on molybdenite flotation, restoring its floatability. Magnesium and calcium ions in seawater play a detrimental role, but ATMP can interact with these ions to improve flotation efficiency.

Studies of benzyl hydroxamic acid/calcium lignosulphonate addition order in the flotation separation of smithsonite from calcite

Cheng Liu et al.

Summary: In this study, a reagent scheme of depressant calcium lignosulphonate (CLS) and collector benzyl hydroxamic acid (BHA) was introduced to facilitate the flotation separation of smithsonite from calcite. The addition order of BHA before CLS was found to be crucial for efficiently flotation of smithsonite from calcite, leading to optimal flotation separation performance.

Tannin: An eco-friendly depressant for the green flotation separation of hematite from quartz

A. Tohry et al.

Summary: Reverse cationic flotation with the natural and eco-friendly organic reagent tannin (TA) selectively depresses hematite while minimally affecting quartz floatability. TA alters the aggregation-dispersion behavior of mineral particles, causing aggregation of hematite and dispersion of quartz. Adsorption analysis suggests that TA chemisorbs onto the hematite surface, while physically adsorbing on quartz surface.
