Copper ores

Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance. These are added separately or, as is becoming common, are supplied as blended products to optimize flotation. Frothers are an important flotation reagent suite consideration.

Copper ores

The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.

Copper in the Environment

The chemical form of copper is very important in determining its biological availability or bioavailability to organisms in the environment. The forms, distribution, transport and potential organism uptake and effects of copper in water, sediment and soil depend largely on the chemical and physical characteristics of the local environment, as well as the bioavailability of different forms to each organism.

Copper mining. From ore to copper.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals

What is Sulfide Mining?

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.
