The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called "collectors" are added to the slurry and bind to the copper particles, making them hydrophobic, or waterproof.
P29 has the potential to selectively recover or significantly reduce entrainment of deleterious minerals that are associated with copper in many major deposits. It is not a leap to say that P29 will be an important part of the concentrator of the future – less energy, less water, better water recovery, and engineered recovery …

Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite is affected by many factors, causing it to easily enter the concentrate and consequently reduce the quality of concentrate. Highly efficient pyrite depressants can be selectively adsorbed on the surface of pyrite to improve its hydrophilicity, thereby …

The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2. The experimental design methodology …
Different species of minerals associated together, whereas the cobalt and cooper elements were hosted in diverse mineral phases, thus the separation of cobalt …
In this research, flotation of copper, lead and zinc minerals from a copper oxide–sulfide ore was studied. The identification tests showed that the sample is a mixture of quartz, chalcopyrite ...
The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. 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 …
As an important strategic non-metallic mineral resource, fluorite has been widely used in various industrial fields, such as metallurgy, optics and semiconductor manufacturing, as well as fluorine-related chemical engineering. Since the major gangue minerals of fluorite ore are silicate and carbonate ones, flotation is the main beneficiation …
Abstract. Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of copper oxide minerals in the mineral processing industry.

Separation of copper sulfide minerals from the gangue is normally carried on in a series of large rectangular steel tanks of capacities from 2 to 28 m 3 equipped with stirrers and compressed air inlets (Fig. 13.4). These provide vigorous agitation and air blowing through the properly conditioned ground ore pulp.
