Effect of calcium, sulphate and gypsum on copper

2014-1-1  This situation prevails in Pb/Cu flotation of a sequential circuit. However, the presence of gypsum during copper activation of sphalerite in the Zn circuit does result into heterocoagulation since activated sphalerite gets positively charged and therefore interacts with negatively charged gypsum (Fig. 4b). Dissolution of gypsum prior to

The interaction of clay minerals with gypsum and its

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.

Impact of gypsum supersaturated water on the

2013-8-1  Gypsum supersaturated process water has been shown to have an adverse effect on the flotation of sphalerite minerals. This study probes the mechanism of such effect by determining the uptake of copper and xanthate on sphalerite in gypsum supersaturated water using zeta potential distribution measurement, atomic absorption spectroscopy, UV–visible spectroscopy and quartz

2015-6-1  Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

Co-treatment of flotation waste, neutralization sludge

2017-12-28  In generally, such copper slag is subjected to recovery copper through flotation, which results in the generation of a large number of flotation wastes, so-called flotation waste of copper slag (FWCS) (Min et al. 2015; Xie et al. 2013). As for the arsenic-containing exhaust gas, it is commonly washed with diluted acid, accompanied by the

Impact of gypsum supersaturated solution ERA

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.

Review of Potential Microbial Effects on Flotation

In flotation, the conditions including oxygen levels, temperature, and nutrients from ore, intake water, and reagents are often favorable for the microbial growth. The mining industry aims to close the water loops, which is expected to result in the accumulation of microorganisms in the process waters with potential effects on flotation

The Effects of Water Recycling on Flotation at a North

Water chemistry and its impact on mineral processing operations are not well understood and often not adequately monitored. CanmetMINING, as part of its water management research program, has been involved in a project initiated to identify opportunities for improving water recovery, water treatment, and recycling in the mining and mineral processing operations.

Effect of Cooling Rate and Slag Modification on the

2020-7-31  The amount of copper flash smelting slag has increased during the recent years along with an increasing slag-to-metal ratio. During slag tapping, some copper sulfide is mechanically entrained. As a result, it is necessary to recover copper matte from the slag by suitable methods. At present, the most common way is slow, controlled cooling in a transfer ladle.
