Solved A froth flotation process is used to concentrate ...
A froth flotation process is used to concentrate copper ore. It is a twostage process that involves one rougher stage and one cleaner stage. The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steadystate.
CopperCobalt ores
Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals.
Specific Effects Of Slurry Concentration, Time And ...
· The froth flotation process will be affected by many factors, like slurry concentration, flotation time, and slurry temperature. But these factors can be adjusted to improve the flotation effect. Let's talk about the specific effects of slurry concentration, flotation time, and slurry temperature on froth flotation in the following article.
Copper Mining and Extraction Sulfide Ores
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.

Optimization of Chalcopyrite Froth Flotation Process by ...
Concentration: The following graph shows the process as a gain of chalcopyrite in concentrates and losses of the same in the tails or tail with respect to the time in the gravimetric concentration and the foam flotation of the sulphide copper ore.
How to Calculate Grade and Recovery with ...
· The ore grade refers to the fraction of a useful element within the ore. It can also be used for gangue as the proportion of a nonvaluable substance, but generally, when we use the term grade, we mean the grade of a valuable element. For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper.

USA
A sequential flotation process for the recovery of highgrade concentrates of copper, lead and cobaltnickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.
