It's a very simple process. The pregnant solution is put into a container of some type with a bunch of scrap iron. The iron will dissolve into the solution, and as it does, it will give up …
Froth flotation may involve multiple stages to maximize copper recovery. The copper-rich concentrate is then thickened and filtered to remove excess water, preparing it for …
The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.
The flotation test results of actual copper sulfide ore showed that pre-magnetized butyl xanthate could increase the copper recovery of copper concentrate by 3.06 percentage points and the sulfur recovery of sulfur concentrate by nearly 3 percentage points, and effectively reduce the mutual content of copper and sulfur concentrates.

If copper tailing is constant, and it very nearly is for a strictly sulfide copper ore, percent recovery must fluctuate almost directly to the feed assay. The accuracy of a recovery figure is first of all dependent on the accuracy of sampling and assaying. Sampling and assaying errors can become quite significant in the case of low grade ores.

Regarding metallurgical recovery, this was assumed in 90% according to what was declared by the company. In the data of Table 1, only the prediction of the fine copper ore in the copper concentrate has been considered, due to the lack of data that relate variables (x_{1}) to (x_{6}) with metallurgical recovery

According to Table 2, copper in the ore primarily exists in the form of copper sulfide, with an oxidation rate of 19.14 %, classifying it as mixed-type copper ore. The content of native copper sulfide accounts for 42.97 %, while the content of secondary copper sulfide is also significant, reaching 37.89 %.Secondary copper sulfide is formed by ...
It is a challenge to recover copper from low grade ore in an environmentally sustainable way, especially from low-grade copper sulfide resources. This paper introduces Zijinshan Mine where an integrated process was developed and applied to recover copper from low-grade copper sulfide ore and acid mine drainage (AMD). The process includes the ...
The copper grade in the tailings is 0.04–0.2%, which is very low in comparison with standard copper ores containing over 0.5% of copper. Because of this, low-grade tailings are not considered an economically valuable copper source at present; however, when copper demand increases and methods to recover copper from tailings are developed ...
Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing …
Combined with the copper grade in the original ore (α), the rougher recovery (ε) could be calculated using the following formula: (1) γ = m 1 m × 100 % (2) ε = γ × β α × 100 %
The better copper recovery from low grade copper ore was achieved through optimized leaching parameters. It was found that the particle size of −63+53 µm can be …
Generally, copper ores are the primary sources of copper, and they exist in two forms, oxides or sulphides. The copper oxide ores, such as cuprite ... The copper recovery increased with increased acid consumption and followed the same trend for water addition up to 60 ml. A leaching efficiency of about 95% was achieved by leaching the ground ...
The variety of slag compositions of Table 1, is inherent to both the concentrate composition and the extraction method applied.Each slag composition requires an appropriate treatment method for further metal recovery or for utilization as construction material [27,28].Thermal reduction of copper smelter slags with solid carbon is commonly applied in …
a 20% share of primary copper produc-tion, heap leaching offers reduced costs compared with the costs of smelting and refining. Those savings result from the omission of energy-intensive ore grinding and flotation. Limited resources of oxidized copper ores, the long leaching time of chalcopyrite, and an inability to recover gold inhibit
It is usually also apparent that the proportion of oxide copper making up the plant feed is very important. This observation is responsible for what is called the ore-type number …

Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various applications, including …
Electro refining the copper you will run into problems because of purity, electro refining and melting copper you will most likely find you could buy copper (and sulfuric acid) cheaper than you could recover copper, and sulfuric acid it in usable or saleable form (time, equipment, electricity, fuel, and other expense may not be worth it), (I ...
The treatment of such an ore by flotation or some other process of concentration has this purpose: to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so. Thus there are two …
Cutoff grades will often be lower, particularly if supported by significant by-product revenues. from which flotation can recover 85 to 90 percent. Ores lower than this grade are normally discarded as waste. Yet primary-sulfide leaching offers a pathway to recover copper from material that is currently below mill head grade and considered waste.
