ABSTRACT. The froth flotation process has been the most widely used mineral concentration technique for more than a century. However, neither flotation columns nor …

Flotation is commonly used to upgrade oxide (Feng et al., 2022;Feng et al., 2023) and sulphide ores, including gold-bearing sulphide ores, producing a gold concentrate enriched in sulphides (Dunne ...

1. Introduction. Due to the easy sliming of siderite, heterocoagulation among siderite, hematite and quartz is a major challenge in the flotation of carbonate-bearing iron ore [1, 2].Although a stepped flotation method was proposed and used to treat the iron ore, the grade and recovery of the concentrates decreased with the increasing …

Most of the world's nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently oc-curs in ores containing predominantly pyrrhotite and various non-sulRdes, …

In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper …

1. Introduction. Pyrochlore (Na,Ca) 2 Nb 2 O 6 (OH,F) is the most economically important niobium-bearing mineral and is typically upgraded by flotation using an amine-based collector. The pulp pH is maintained between 5.5 and 7 in the rougher circuit and is gradually dropped to as low as pH 2 in the final cleaner stage …
