Investigation of Flotation Parameters for Copper Recovery from Enargite and Chalcopyrite Mixed Ore Kazutoshi Haga+, William Tongamp and Atsushi Shibayama Faculty of Engineering and Resource Science, Akita University, Akita 010-8502, Japan

The interaction of two clay minerals, kaolinite and bentonite with gypsum and its effects on the flotation of a copper–gold ore was investigated in this study. It was found that bentonite increased the viscosity more than kaolinite when mixed with the copper–gold ore at low shear rates.

Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering "system", in that the various important parameters are highly inter-related, as .

The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...

Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.

This paper presents the sulfidisation promotion effect of ammonium sulfate on the sulfidisation flotation of both malachite and copper oxide ores. Copper oxide ores are commonly difficult-to-float due to its molecular structure, and adding sodium sulfide as activator is necessary; however, its dosage to the flotation pulp must be strictly controlled, as it is also a powerful depressant for ...

Gypsum supersaturation in process water is known to have detrimental effects on flotation performance of sulphide minerals. The motivation of this research is to develop a better understanding of the impact of gypsum supersaturation in process water on sphalerite flotation.

the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process

A copper collector may also be added at this point. The pulp progresses to the flotation cells. The frother and copper collector are usually added to the pulp just before the roughers. Additional copper collector is often added to the scavenger flotation cells and may be added at several other points.

The addition of electrolytes considerably increases the recovery of mineral matter in coal flotation. In this paper, the effect of calcium ion on coal flotation in the presence of kaolinite clay was investigated through microflotation experiments on a mixed coal–kaolinite system. The interaction behavior and mechanism between coal particles and kaolinite were indicated by a rotational ...

This paper aims to understand the fundamental interaction mechanism between molybdenite and kaolinite in gypsum solution using kerosene as collector. Micro-flotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral. The results showed that the recovery of molybdenite decreased from 86% to 74% ...
