Copper Flotation - Metallurgist & Mineral Processing Engineer

Gangue slimes (typically clays and talc) can be an issue because of preferential adherence to bubble surfaces that 'crowd out' copper mineral collection onto bubbles. Misplacement of gangue slimes to concentrates also can pose significant concentrate dilution issues as well as requiring much higher flotation residence times to ensure high copper mineral recovery. In a plant where the ...

Froth flotation - Wikipedia

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts. The copper has concentrated almost ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Gangue | geology | Britannica.com

Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper. The production of concentrates ...

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.

As regards the average grade of concentrate, no more can be said than that it depends on the class of the copper-bearing minerals present and their mode of occurrence and on the character of the gangue. It usually contains over 20% of copper, but a difficult chalcopyritic ore may yield a concentrate with less than that percentage, while it is theoretically possible to obtain one running over ...
