Copper Mining and Extraction: Sulfide Ores

The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated. ...

A sequential flotation process for the recovery of high-grade concentrates of copper, lead and cobalt-nickel 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.

Sulfides, Selenides and Tellurides: rebellious and ...

Sulfides are generally fairly dense and heavy, so they can be recovered by simple gravity methods. Vibrating tables are sometimes used for this purpose and the sulfides will usually show up in the table middlings. However, in most commercial milling operations, sulfides are recovered by a method called flotation.

Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).

Sulfide Ores - an overview | ScienceDirect Topics

Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic). ... from the gangue.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

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.
