The influence of humic acid on the flotation of galena under different redox conditions was
studied based on micro-flotation experiment. The results showed that the humic acid was an …

Sawdust was used as cheap sorbent for the remediation of a diesel and oil fuel-
contaminated mining soil whereas biosolids were evaluated as collectors and frothers in …

Amyl-4-amino-1, 2, 4-triazole-5-thione (AATT) reacted with Cu 2+ or Pb 2+ ions in aqueous
solutions to form CuAATT and Pb (AATT) 2 complexes and their solubility product constants …

The aim of this study is to apply process mineralogy as a practical tool for further
understanding and predicting the flotation kinetics of the copper sulfide minerals. The …

This study aims to investigate the effects of operational variables on concentrate grade,
recovery, separation efficiency, and kinetic parameters of the copper flotation process. For …

One of the water constituents that has not been investigated in great detail for potential
detrimental effect on mineral flotation is organic matter. This study investigates the effect of …

The interaction mechanism of sodium diisobutyl dithiophosphinate (DTPINa) with
chalcopyrite, pyrite, galena and sphalerite was investigated by single mineral flotation …

Biosolids and representative compounds of their main components–humic acids, sugars,
and proteins–have been tested as possible environment-friendly collectors and frothers for …

Surface Tension (ST) of water solutions of humic acids extracted from volcanic ash derived
soils (soil humic acids, S-HA), were measured under controlled conditions of pH (13.0) …

The particle separation efficiency by flotation sharply decreases or even completely fails
when the diameter of dispersed particles falls into the nanoscale. In the present laboratory …
