Chalcopyrite and pyrite floatabilities in the presence of ...

In this study, the effect of sodium sulfide, sodium metabisulfite (SMBS), and their dosages (100, 200, 300, and 400 g/t) were investigated on chalcopyrite and pyrite floatabilities in a high pyritic copper sulfide ore. Furthermore, the role of particle size distribution (PSD) in three different levels (i.e., d70, d75, and d80 of passing 75 µm ...

Agglomeration of fine-sized copper ore in heap leaching ...

Fig. 2 shows the particle size distribution of the fine-sized copper ore-based agglomerates synthesized by the addition of various amounts of metakaolin. In the raw material, fine particles smaller than −1.6 mm in size accounted for 51.37 wt%, and after agglomeration, the fine particles almost disappeared.

Copper Concentrates - Cargo Handbook - the world's largest ...

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

ideal particle size copper ore grinding

Copper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was performed.

Experimental evaluation of a mineral exposure model for ...

designed and operated to crush the ore to an appropriate particle-size distribution so that copper mineral grains are exposed and can be leached. In this regard, based on the approach of Hsih, Wen, and Kuan (1995), a mineral exposure model has been evaluated to describe the extent of grain exposure as a function of particle size.

Agglomeration technique improves heap leaching process ...

Particle size and shape are two important parameters in optimizing heap permeability. Without agglomeration, fines clog spaces between larger ore particles in the ore bed, preventing the leachate from flowing through and ultimately reducing the amount of recovered ore.
