Nov 01, 2011· Concentrate weight and assays were used to calculate copper and iron recoveries, copper concentrate grade, and concentration and enrichment ratios for each one of the three different froth flotation procedures. Further, the total organic carbon content (TOC) was quantified using the Walkey-Black wet combustion method (Nelson and Sommers, 1996).
The chemical composition of the low iron content For example, both an increase and decrease in copper sphalerite sample, ZnS, (Carthage, TN, USA) was activation, collector adsorption and froth flotation of 66.7% Zn, 0.3% Fe and 32.7% S (0.06% Cu and 0.07% Pb) while that of the high iron content sphalerite sam- * ple, (Zn, Fe)S, (Broken Hill ...
iron recovery ranged from 87 to 89 percent; this represents a recovery of approxi-mately 99 percent of the magnetite present. Cleaning of the flotation concentrates yielded copper products that assayed 19 to 25 percent Cu. Copper recovery ranged from 69 to 87 percent, depending upon the copper content of the various samples.
Aug 01, 2019· The hydrated form of copper ions in the sulphate salt shows a noticeable, visible blue colour at concentrations higher than about 200 mg/L (of Cu). The results observed for ion flotation of copper ions at 500 mg/L indicates that using the N-octanoyl-cys causes the colour to rapidly disappear, which verifies the results obtained in Table 5.
Jul 09, 2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was ...
The average copper and iron recovery obtained was from 60% to 70% and from 2% to 3%, respectively. These results indicate that the old flotation tailings pond represents an important source of secondary raw material for the extraction of copper and that it should be valorized rather than land reclamation. At the end of the paper, a mechanism of ...

Pine oils, cresylic acid, and long-chain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium,
The flotation process may also be conducted in reverse by depressing the molybdenite with the addition of a dextrine solution to the pulp. The copper and iron sulfides are floated and the molybdenite is depressed. In this process, it is necessary to treat the dextrine before trying to thereafter clean the molybdenite by floating.
