Copper Flotation Mineral Processing & Metallurgy

Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate. It is not unusual to grind the rougher flotation concentrate to minus 200-mesh for more complete

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

ABSTRACT Orway Mineral Consultants

copper concentrate can be penalised. Copper concentrate containing high levels of impurities is not acceptable to some smelters. This can render them unsaleable in some countries as in the case of the high arsenic containing concentrates from the Pacific Rim. To permit treatment and to maximise the value of a copper concentrate, the levels of

Copper Concentrate Thickening and Filtering. The final cleaned flotation concentrate flows or is pumped to a Spiral Rake Thickener. A Adjustable Stroke Diaphragm Pump, mounted on the thickener superstructure, meters the thickened concentrate to the Disc Filter. The Thickeners are often used to store concentrates for filtration at fixed

Flotation separation of copper sulphides from arsenic

Arsenic minerals pose a problem for copper flotation concentrates since they are often associated with copper minerals, display similar flotation behaviour to copper minerals and therefore report to final copper flotation products. Despite extensive research, the rejection of arsenic minerals in copper flotation is still a challenge.

Copper Trading | Redstone Commodity Search

Copper is a metallic element found in ore deposits around the world, the main copper ores being chalcopyrite, bornite and malachite. Ore is extracted either through mining (open pit or underground), or leaching. To make it commercially valuable, the ore is ground and the valuable elements are separated from the unwanted material through froth flotation. The copper concentrate is then roasted

Copper processing Ores | Britannica

Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.
