the part of cooper oxide either by leaching of grinded ore prior the flotation or by leaching the flotation tailing coming out from the concentrator. Direct leaching process of copper oxides or complex ores attracts considerable scientific and engineering attention, which plays an important role in the sus-tainable development of copper industry.

's reliable beneficiation technology considerably improves the contained value of the ore by removing gangue minerals using flotation, gravity separation, magnetic separation, washing and leaching.

Abstract. In copper dump leaching, run-of-mine ore is irrigated with acidic leaching solution to generate aqueous cupric ions for further processing. The very large size of the ore particles being leached, as much as two meters in diameter, should preclude any significant metal recovery. Dump leaching should not work; and yet it does.

leaching system for the leaching of gold and copper from high-sulfide and copper-bearing flotation tailings generated from a gold mine. Potassium permanganate, as a common strong oxidant, was selected as the oxidant for the leaching system. Ammonia, known for its high efficiency in leaching copper [15], was introduced into the system for …

The presence of copper(II) ions in the process water used in the mineral processing industry has an impact on iron and nickel sulphide mineral flotation in both acidic and alkaline environments.

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 …

Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per …

One copper concentrator reported a 3% reduction in the +65 mesh fraction in their flotation feed by placing more emphasis on their cyclone maintenance program. Conclusions

This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this ...

Proper cyclone geometry reduces the amount of coarse topsize in the circuit product. Liner fit and condition are critical to maintain proper cyclone geometry. One copper concentrator reported a 3% reduction in the +65 mesh fraction in their flotation feed by placing more emphasis on their cyclone maintenance program. Conclusions

The addition of copper and citrate in thiosulfate solutions can accelerate gold dissolution rate by about an order of magnitude. For the copper-citrate-thiosulfate system, thiosulfate ion works as the complexing agent for aurous ion, and it is extremely critical to the gold leaching process. The results of kinetic analysis of the leaching data ...

PDF LEACHING OF FLOTATION TAILINGS - Univerzitet u Zenici. Based on the results, shown in Figure 4, the optimal ratio of S:L for the copper leaching process from flotation tailings is 1:2.5.

This, of course, will vary with the nature of the ore. In one plant that employs gravitation previous to flotation the fine sand and slime only are treated at the rate of 50 tons per rougher. The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners.

A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but …
