A New Technique for Recovering Copper From Complex Copper Oxide Ore …
Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide …

The future of flotation
For example, Barrick is using its own patented flowsheet for a very complex refractory gold ore body. The process ("Mill-Chemistry-Float-Mill-Chemistry-Float") involves floating the coarser particles in the feed first, regrinding, and then floating the fines but enabled with appropriate chemistry to suit the coarse and fines separately.

The processing route of xenotime is similar to that of monazite. 2.5.2 Ion Adsorption Clays. Commercial mining and processing of these types of ores are currently exercised only in China. The REO assay in this ore is too low, and it lies around 0.05–0.2%. Therefore, ore beneficiation does not have much role in the processing route.

Processing of Complex Materials in the Copper Industry
A global copper mine-by-mine review undertaken by ICSG found that the global average copper ore grade was as low as 0.45% copper in reported reserves and only 0.65% copper in 2015 copper mine production. Global weighted average of copper concentrate output in a large sample of plants was around 25% copper in 2015 data.
