The copper ore in Chilean porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide generally mined from various locations the mining site; thus, mineral composition, oxidation degree, particle size, and grade vary. Therefore, operation, it common to blend ores spots then process them using flotation. In this study, floatability of five types Cu–Mo b...

Recently, several studies have shown the positive effect of sulfidization flotation on malachite surfaces and its enhancing methods. Therefore, this paper was focused ammonium sulfide sodium malachite, respectively; investigated using different devices such as micro-flotation tests, Zeta potential measurements, ToF–SIMS, XPS analysis, FTIR. Thus, Fourier transform infrared spectroscopy results ...

The effects of ferrous and ferric iron as well as redox potential on copper and iron extraction from the copper flotation concentrate of Sarcheshmeh, Kerman, Iran, were evaluated using shake flask leaching examinations. Experiments were carried out in the presence and absence of a mixed culture of moderately thermophile microorganisms at 50 ̊C. Chemical leaching experiments were performed in the...

A rapid flotation method for separation and enrichment of ultra trace amounts of copper(II), cadmium(II), nickel(II) and cobalt(II) ions from water samples is established. At pH 6.5 and with sodium dodecylsulfate used as a foaming reagent, Cu2+, Cd2+, Ni2+ and Co2+ were separated simultaneously with 2-aminocyclopentene-1-dithiocarboxylic acid (ACDA) added to 1 l of aqueous solution. The propose...

The copper ion is a common metal in the pulp beneficiation industry, and it affects recovery of target minerals. In this study, we investigated interaction mechanism ions with surface sulfidized malachite its effect on flotation. flotation behavior hydrophobicity were studied by microflotation contact-angle tests. experimental results showed that modified suitable concentration was enhanced inc...

Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with Analysis Variance (ANOVA) test to establish effect input factors on output factors. However, when this mineral flotation, its polynomial model usually performs poorly. An alternative use artificial neural networks (ANNs) such situations. Within context, ANOVA ...
