Collectorless flotation can be demonstrated in plant practice, but there is usually little incentive to exploit as there is no easy way to determine if collectorless flotation will be robust to ore changes and collector addition removes that concern (Leroux et al., 1994).

Selective flotation of sulphides from a gold mining operation
this study was to evaluate the performance of reagent systems for the selective flotation of sulphides (chalcopyrite, sphalerite and galena) from gold flotation concentrate collected in the new plant at company, because these samples have higher amounts of sulphides, optimizing the results of the study.

Lime use and functionality in sulphide mineral …
Typical flotation flowsheets involve either sequential flotation of Cu (first) and Ni (second) from the ore (e.g., Strathcona and Kevitsa mines), or bulk flotation of the sulphides and subsequent Cu-Ni separation (e.g., Thompson, Clarabelle, Jinchuan and Norilsk).
Contribution of the Greenland Ice Sheet ... - …
01.06.2019 · The Greenland Ice Sheet holds 7.2 m of sea level equivalent and in recent decades, rising temperatures have led to accelerated mass loss. Current ice margin recession is led by the retreat of outlet glaciers, large rivers of ice ending in narrow fjords that drain the interior. We pair an outlet glacier–resolving ice sheet model with a comprehensive uncertainty quantification to estimate ...

Sulphide Gold Ore Treatment by Leaching and …
There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used.. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.
Froth flotation - Wikipedia
The process was not froth flotation but used oil to agglomerate (make balls of) pulverised sulphides and buoy them to the surface, and was patented in 1898 (revised 1901). The operation and process was described in the April 25, 1900 Transactions of the Institution of Mining and Metallurgy of England, which was reprinted with comment, June 23, 1900, in the Engineering and Mining Journal , New York City.
