The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the …

This project is a "Copper flotation" project with some Moly (<200ppm). The chosen scale-up was 2.5 while The Book calls for on copper 2.1X. Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.
Various flotation reagents that are commonly used for copper flotation were identified, selected and used during the flotation test work in order to identify the best reagent best suited to float the copper slags. Potassium amyl xanthate (PAX) and Flotanol CO 7 were used in all tests as the primary collector and frother.
Copper flotation process Mining – separating minerals by flotation Measurement made easy — Introduction The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another mineral. The process starts with crushed ore. A ball mill

The first class includes copper, lead, lead-zinc, copper-zinc, and copper-lead-zinc ores. Both gold and silver may be present, the gold values being usually associated with chalcopyrite and pyrite, and the silver with galena and tetrahedrite. ... may carry gold that is too coarse to float into the flotation circuit, with the result that such ...
Several attempts have been done, aiming to recover copper from flotation tailings through mainly acid leaching [17], and froth flotation [4].Using the latter, the recovery of copper through reprocessing of tailings has been studied both in the laboratory and on the pilot scale with an emphasis on the concentration of reagents and a pre-economic analysis [18].

The conventional view of the flotation size-recovery curve is shown in Figure 1. There is a good reason for this view – if you sample almost any flotation plant you will produce a similar curve. The numbers speak for themselves – fine particles float poorly in most plants. Operators carefully avoid "overgrinding" and "sliming" of feed.
Some researchers explored the separation between copper sulphides and pyrite in flotation at alkaline pH. For example, Yin et al. (2019) investigated the effect of pH on covellite and pyrite flotation and found that a high selectivity of covellite flotation against pyrite was achieved when flotation pH was greater than 10 as a result of strong pyrite depression.

The broken bonds on copper oxide mineral surfaces, such as malachite, are mainly ionic and have strong hydrophilicity, which makes it difficult for xanthate collectors to be used directly in flotation of copper oxide minerals [5]. Therefore, the main direct flotation methods for copper oxides are chelating-reagent flotation and fatty-acid ...

GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried 44% insoluble matter, which could be reduced by re-treatment.
