Controllable-Domain-Based Fuzzy Rule Extraction for Copper

In copper removal process control, the commonly used technique is the so-called rule-based control, which is largely dependent upon the operators' experience, likely leading to unstable process production due to each individual's characters and favors. In this paper, to enhance the effectiveness of process control, a controllable-domain-based fuzzy rule extraction strategy is proposed. New

Solvometallurgical process for extraction of copper from

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

Innovations in Copper: Mining & Extraction: Producing copper

Bioleachingis the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached. An associated process is bi

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
