Flocculation has been a successful method to improve the processing of fine valuable minerals [16]. In this process, flocs or aggregates are produced by long-chain water-soluble polymeric molecules. These polymers initially adsorb onto a mineral particle surface due to electrostatic forces, chemical interaction and/or hydrogen bonds.

This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotation.

Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper …

The treatment of copper sulfide minerals containing a high percentage of oxide copper causes problems in the concentration process, decreasing the copper content.

It is well known that particle size plays a critical role for the froth flotation, especially for flotation separation between two or more minerals [4, 5].Grinding is necessary to achieve one mineral liberates from other minerals, as a result, fine grinding of coarse-grained minerals is of interest to the mineral processing plant for its higher …

When the particle size of the copper minerals is relatively coarse and the nickel minerals are fine-grained, the process flow of copper preferential flotation-copper-nickel mixed flotation can be used. The above is the comprehensive beneficiation and recovery process of three common copper ore associated minerals.

The work includes a demonstration of segregation of large tonnages of low-grade ore as definitively as possible within the constraints of an operating mineral processing plant. The Kansanshi copper mine is operated by First Quantum Minerals (Torrealday et al., 2000). At this site, both oxide and sulphide copper minerals are …

Current favorable tools for performance evaluation use numerous parameters such as particle size, throughput, mass % to be rejected, accurate identification of the particles, and even particle shape to determine efficiency, performance, and accuracy of the sorting process in mining/mineral processing industry.

Mineral systems of copper sulphides and copper–arsenic sulphides were tested, including a 1:1 mix of tennantite and chalcopyrite. The copper minerals could be separated from the copper–arsenic minerals due to more collector adsorption and less oxide/hydroxide species on the surface of the copper only minerals.

List of process engineering tasks for comminution and classiication » – integration of additional processes such as leaching, extraction or reactions with comminution in grinders – prediction of material adhesion in grinders and classiiers and avoidance strategies – deployment of grinding aids to alter the grinding limit and reduce the ...

Applied across the industry, improved coarse particle flotation can result in an additional 0.5 million to 1.5 million metric tons of annual copper production by 2032. If applied across all metals found in …

Column leaching results also show that about 80–90% of the copper was recovered from the copper sulfide ore in a relatively short leaching time irrespective of crushing technique. As expected, copper recoveries improved with a decrease in the particle size of the copper sulfide ore as exposure of copper mineral grains increased.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are …

A Brief Review on Micro-particle Slurry Rheology in Grinding and Flotation for Enhancing Fine Mineral Processing Efficiency May 2023 DOI: 10.20944/preprints202305.0725.v1

Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).

Minerals processing is the most energy-intensive part of upstream copper production and can contribute significantly to a site's emission profile. Minerals Processing identifies how mining companies, working in partnership with stakeholders, can embrace innovation using a 'systems approach' to speed collaboration, knowledge and impact.
