Copper extraction refers to the Copper ores containing chalcopyrite and the dense metal particles do not react with froth flotation media. Typically, if

The Depressing Effect of Clay Minerals on the

The floatability of chalcopyrite was evaluated through microflotation tests that were carried out in a 150 mL Partridge and Smith glass cell using nitrogen (N 2) at a flowrate of 20 mL/min. The flotation feed was prepared mixing 1 g of chalcopyrite with different amounts of fine particles of kaolinite/smectite, i.e., 0, 45, 60, 75, and 150 mg of clay.

Challenges and opportunities in the recovery/rejection

The higher association of gold with pyrite rather than chalcopyrite is a challenge in coppergold flotation circuits, since pyrite is widely recognised as a gangue mineral in copper ores. Understanding the mineralogy, liberation and association of gold as well as the associated gangue minerals in a flotation feed is crucial to optimise gold recovery.

The effect of nontoxic depressants in chalcopyrite flotation

Sulfidic copper ores are generally enriched by flotation. The major source of copper is chalcopyrite concentrated from sulfidic copper ores. Therefore, the determination of depressing mechanism for selective flotation of minerals such as chalcopyrite, pyrite, sphalerite, galena from complex sulfidic ore is very important.

Chalcopyrite deposits across the globe are as represented in Fig. 1. It is a fairly common mineral and therefore, only the finest of localities will be mentioned.

Effect of Sodium Sulfite on Floatability of Chalcopyrite

Sodium hydrogen sulfide (NaHS) is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. However, the process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas (h4S) under acidic conditions.

Development of copper recovery process from flotation

In the earths crust, copper is most commonly present as copperironsulfide and coppersulfide minerals, such as chalcopyrite (CuFeS 2) and chalcocite (Cu 2 S) [1,2]. About 80% of the worlds copper ores originate in CuFeS minerals, especially chalcopyrite, which is the most refractory minerals and not easily dissolved in
