The flotation recovery of cuprite is unsatisfactory because of its natural hydrophilic surface,
which decreases the flotation index of copper concentrate. One can modify the cuprite …

Cuprite is an important copper-oxide mineral that is difficult to recover in flotation. Therefore,
it is necessary to study the flotation behavior of cuprite to recover copper resources. In this …

The pulp from the sulfidization flotation of copper oxide ores contains several metal ions,
among which ferric ion (Fe 3+) depresses the flotation of copper oxide minerals. Thus, it is …

The direct sulfidization of cuprite is inefficient because cuprite is a copper-oxide mineral with
a strong surface hydrophilicity. In this study, oxidant was used to modify cuprite surfaces to …

Although azurite is one of the most important copper oxide minerals, the recovery of this
mineral via sulfidization-xanthate flotation is typically unsatisfactory. The present work …

Enhanced sulfurization has always been the focus of flotation research on copper oxide
minerals. In this study, ethylenediamine (EDA) was used to improve the sulfurization of …

Utilizing xanthate in bulk flotation of Cu-Mo sulfide ores is inevitable, but the implication of
xanthate on the flotation of molybdenite fines is barely understood. In this study, the …

Among copper oxide ores, the reserves of azurite are second only to those of malachite.
However, little information is available regarding the flotation behavior and mechanism of …

NH 4 HSO 4 was used as an activator to improve the sulfidization flotation of azurite, with Na
2 S as the sulfiding agent and butyl xanthate (NaBX) as the collector. Microflotation, contact …

Enhancing the sulfidization of copper oxide minerals has been widely studied to improve
flotation recovery. In this study, we investigated azurite surface modification with lead ions …
