In this study, the flotation behavior of malachite was investigated using carboxyl-functionalized carbon black nanoparticles (CB-NPs) as collectors in a hydrodynamically simplified Hallimond tube. We found that malachite floatability increased with i

Bench-scale selective bioflotation tests were carried out in a 1 L Denver cell using Rhodococcus opacus ( R. opacus ) cells as a collector in malachite–silica binary mixture and copper (Cu) oxide ore systems. Through the first set of tests carried

In this study, a flotation process is proposed for separating the arsenic-bearing minerals to recycle the soil surrounding the Janghang refinery in South Korea, which contains a high level of arsenic. To maximize the arsenic recovery, several experim

We investigated the influence of a salt solution on the flotation behaviour of synthetic malachite using a sodium oleate as a collector. We found that the floatability of oleate ions-adsorbed synthetic malachite monotonically increases with an increa
