copper leaching behavior

Leaching behavior and immobilization of copper flotation

In this study, the leaching characteristics of copper flotation waste have been evaluated by the Toxicity Characteristic Leaching Procedure (TCLP), Synthetic Precipitation Leaching Procedure (SPLP), Extraction Procedure (EP Tox), and Field Leach Test (FLT) tests methods. The adsorption capacities and adsorption efficiencies were determined.

CONTAMINANTS OF POST-LEACHING COPPER SOLUTIONS AND THEIR

Contaminants of post-leaching copper solutions and their behavior during extraction 135 sons is that they do not need to be blended with modifiers. They can be stripped with a typical copper electrolyte (Kordosky, 2003; Merigold, 1996). To extract copper other chemical compounds can be used, e.g. β-diketones, having structure of R 1COCH 2 COR

Leaching of a copper flotation concentrate with ammonium

The leaching behavior of a copper flotation concentrate was investigated using ammonium persulfate (APS) in an autoclave system. The decomposition products of APS, active oxygen, and acidic medium were used to extract metals from the concentrate. Leaching experiments were performed to compare the availability of APS as an oxidizing agent for leaching of the concentrate under atmospheric

Applying Softcomputing for Copper Recovery in Leaching Process

This paper describes the work done with ANN to generate behavior predictions of the pile in the copper leaching domain. The use of ANNs has been used in combination with other techniques commonly used as a predictor in the mining industry, such as linear regression, with the aim of contrasting and enhancing the quality of results.
