An Investigation of Copper Recovery from a Sulphide-Oxide Ore with a Mixed Collector System
… research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged. The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime. …

Biooxidation and Thiocyanate Leaching of Refractory Gold Ore in One-Step
Gold is among the precious metals and for more than a century, it has been extracted by the cyanidation process. Cyanide is highly toxic for humans and living organisms. Moreover, with increasing gold extraction over time, the average gold grade in minerals has decreased and simultaneously cyanide …

Etude de la flottabilité de la malachite à l'aide de l'amylxanthate de potassium et d'un acide gras. (Cas d'étude: Flottation du minerai oxydé de Kamfundwa au Katanga en RDC)
… scale. The first part of our results concerns theoretical aspects related to floatability of malachite. Due to their surface properties, oxides are difficult to float with common xanthate collectors used in the industry in contrast to sulfide minerals. Therefore the surface state of malachite was …

Deep Eutectic Solvents for the Leaching of Cobalt from Oxide Ores
… respectively. Conventional processing of these ores is currently extremely energy-intensive and/or utilises toxic mineral acids, whilst the high degree of variability of Co ore mineralogy and geochemistry makes its extraction inefficient and technically challenging. As a result, there is a …
