Comminution in stirred media mills is a frequently applied top-down method towards the
production of micron-and submicron particles. However, due to the high energy density, this …

Stirred media mills are used by the mining industry for ultrafine grinding to enhance
liberation, and to decrease particle sizes of industrial minerals to tailor functional properties …

The present work investigates the role of hydrogen peroxide and collector type in differential
flotation of pyrite and arsenopyrite model minerals without acid pretreatment …

Differences in the oxidation rate and extent of model pyrite and arsenopyrite minerals,
augmented by pulp aeration, was investigated using dissolved oxygen demand tests and X …

Pressure oxidation is a widely accepted method to treat refractory gold ores. Gold recovery
is generally lower from alkaline than acidic pressure oxidation discharge due to passivation …

Thionocarbamate collectors are noted for their high flotation selectivity against pyrite under
alkaline condition. In this study, selectivity of O-isopropyl-N-ethyl thionocarbamate (IPETC) is …

A comprehensive mineralogical and physico-chemical examination of two refractory gold
ores and concentrates from the Ghanaian gold province was conducted to gain a better …

Chemical oxidation is a promising pretreatment method for refractory pyrite enclosure to
enhance Au/Ag extraction. Here, persulfate was employed for stepwise oxidation of a …

This paper presents a research overview, reconciling key and useful case study findings,
towards uncovering major causes of gold refractoriness and maximising extraction …

The mining sector generates massive quantities of mine tailings in response to the ever-
growing demand for mineral products. Mine tailings (MTs) pose a major environmental …
