A method is provided for recovering nickel from a copper refinery tankhouse electrolyte as a nickel containing or nickel-copper containing cake. According to this method, a portion of the electrolyte is decopperized to a desired level of copper concentration and the so decopperized solution is subjected to an acid retardation operation, so as to separate it into a strong acid stream and a …

emewCorporation offers copper recovery solutions for copper refineries and mining enterprises using vortex electrowinning.
The primary goal of these arrangements can be categorized in two ways; the recovery of copper and then the recovery of valuable target metals, or the recovery of all valuable elements at the same time (Morrison, 1963, Scott, 1990, Langner, 1997, Hoffmann, 2000, Davenport et al., 2002, Amer, 2003, Chen and Dutrizac, 2005, Rao, 2006, Ojebuoboh ...
Cyanide-free, sulphate-based copper electroplating waste solutions and spent nitric acid solutions from the etching of copper were investigated for copper recovery by cementation.
Traditional copper flowsheets were developed to process high grade ores and require adjustments for the recovery of metals from low grade materials (Spooren et al., 2020).
uranium, a copper smelter, a copper refinery, and a recovery circuit for precious metals. Equivalent Systems The following equivalent systems were applied: Equivalent systems are determined by the Copper Mark to have standards and assurance requirements that are materially comparable in scope and intent to those of the Copper Mark,
A primary copper smelter and refinery thus has six subsystems for copper production and about 15 subsystems for internal recycling, waste treatment, and recovery of valuable products. Figure 1. The process routes of primary copper production [10]. The primary smelter and refinery plant uses concentrate as a raw material, produces copper
Copper blister produced will undergo copper refining in Copper Tank House where copper cathodes of 99.99% purity are produced. Slime deposited at the bottom of the tank will undergo a hydro metallurgy process in our specially designed high tech recovery equipment with an auto dosing system to optimally recover the precious metal.
We also evaluated the recovery performance in 1 ton/d pilot-scale process using wastewater from copper-refining process; 90% metal ion rejection was achieved, with the exception of calcium ions, even at 95% recovery rate.

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 ...
Rio Tinto reports mined copper production of 138 thousand tonnes was 10% higher than the third quarter of 2021 due to higher grades and recoveries at Kennecott, partly offset by lower grades and recoveries at Oyu …
The significant amount of selenium and tellurium present in copper refinery slimes often makes the recovery of these elements not only desirable, but economically viable. While a variety of processes have been developed to this end, some are more feasible because they recover greater values and are environmentally safer.
The copper refining slag is generated from a copper pyrometallurgical refining process. It is mainly comprised of metallic Cu, Cu oxides (CuO & Cu 2 O) and some silicates (Fe, Co silicates, etc.), which poses a threat to environmental safety while loaded on the land without treatment (Hejna et al., 2018; Zheng et al., 2021).
