Our chalcopyrite mining hazards

Copper extraction - Wikipedia


As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using ...

Pyrite - Wikipedia


These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the form it takes in most mining operations. Acid drainage. Sulfate released from decomposing pyrite combines with water, producing sulfuric acid, leading to acid rock drainage.

It is clear that floated free chalcopyrite in first cells is the highest which decreases in further cells. In terms of particle size, proportion of chalcopyrite in size fraction below 50 µm is considerably high throughout the whole process. It should be noted that the feed type has almost no effect on the flotation of free chalcopyrite.

Chalcopyrite - Wikipedia


Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. Occurrence. Chalcopyrite is the most important copper ore.

Galena: The mineral galena information and pictures


Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its importance ...
