Reagent removal is an indispensable step to further separation of the copper sulfide ore
flotation mixed concentrate, and xanthate is one of the most commercially used collectors for …

Perilla protein (PP) is abundant in the perilla processing wastewater, and its recovery would
result in large productive and financial advantages. This work introduces a novel method …

In the flotation of complex copper ores containing chalcopyrite in seawater, sodium
metabisulfite (SMBS) has been widely used as a pyrite depressant. Here, calcium ions in …

Redox potential (Eh) of the pulp dominates Zn-S selective flotation, and regulating Eh can
maximize Zn grade and recovery of Zn rougher concentrates. However, reasons accounting …

In this paper, 4-amino-3-thioxo-3, 4-dihydro-1, 2, 4-triazin-5 (2H)-one (ATDT) was
synthesized and introduced as a depressant for selective flotation separation of molybdenite …

Zinc occupies a vital position in modern industrial production, and zinc metal is mainly
extracted from marmatite or sphalerite. Marmatite or sphalerite is often associated with pyrite …

Mineral extraction is facing increasingly severe challenges in terms of environment
protection and cost reduction. Abundant of lime and sulfuric acid were consumed in the …

Flotation of grinding products with 55, 60, 65, 70, and 75% of grain size< 74 μm, was
conducted at the pulp's pH values of 10 and 12. Higher copper recovery was obtained in …

In Pb–Zn ore flotation, unintentional activation of sphalerite often leads to difficult separation
of Pb and Zn minerals, during which grinding plays a key role in unintentional activation …

Three novel acyl thiobenzamides including acetyl thiobenzamide (ATBA), butyryl
thiobenzamide (BTBA) and trimethylacetyl thiobenzamide (TTBA) were synthesized and first …
