Pressure leaching las cruces copper ore SpringerLink

A hydrometallurgical process was developed for treating the Las Cruces massive sulfide-ore deposit located near Seville, Spain. A two-stage countercurrent leach process, consisting of an atmospheric leach and a pressure leach, was developed to effectively leach copper from the copper-bearing minerals and to generate a solution suitable for the subsequent solvent-extraction and copper-electrowinning operations.

Leaching of Primary Copper Sulfide Ore in Chloride

Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatures. The study focused on whether this chemical leaching system could be applied at an industrial scale. Leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore; the ...

Agglomeration of fine-sized copper ore in heap

2020-12-1  1. Introduction. Heap leaching is a low-cost, flexible hydrometallurgical process for recovering valuable metals from low-grade ores (Nosrati et al., 2012).In this process, the ore bed must be porous and permeable to permit flow of the leach solution (Lewandowski and Kawatra, 2009a).However, fine particles usually migrate into the porous structures and clog the natural flow paths, because of ...
