Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, & Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5 O 2 + H 2 SO 4 → Cu 2 + + SO 4 2 − + H 2 O.


A Study on Selective Flotation in Low and High Pyritic Copper Sulfide Ores. September 2016. Separation Science and Technology 51 (13):2214 - 2224. DOI: 10.1080/01496395.2016.1202980. Project: A ...


Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...


Currently, different metal sulfides (NiS, Co9S8, FeS2, and CuS) have been extensively studied as alternative electrodes for rechargeable batteries that can satisfy the performance requirements for more powerful energy supply and storage technologies for various applications and industries. Among them, copper sulfides have gained significant attention as a promising electrode …


Since the publication of this classic study, the practice of anode copper production from sulphide concentrates has experienced many changes. The reverb furnace, that was the dominant copper smelting technology in the 1970s, has been replaced by far more energy efficient and environmen-tally sound flash and bath smelting technologies.


Copper sulfide (CuS), a plentiful, low‐priced, and nontoxic transition metal sulfide, is going to be a promising anode material with high capacity and excellent rate performance for energy storage.

A study was conducted for metal recovery from low-grade copper sulfide tailings using the leaching and fractional precipitation methodology. Mineralogical characterization of the materials shows that the primary weight proportions of pyrite minerals, silicate minerals, and quartz in tailing are 31.50%, 38.85%, and 15.06%, respectively.

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".


Copper sulfide ores are at a disadvantage when it comes to chemical methods of extraction, since the sulfides are barely soluble in acid. ... Inuit technology was non metal using,yet they ...


The technology should be suitable for retrofits, e.g., the conversion of a copper heap leach, solvent extraction (SX) and electrowinning (EW) facility once the oxide and transition material is exhausted (Valkama, 2013).
