Study of Flotation Parameters for Copper Recovery from ...
Figure 1: Recovery of copper as a function of particle size Obviously the grinding performance significantly affects further separation results. Significant reduction in grinding size would be necessary to achieve good liberation. However, the fineness of grinding depends on the variation in hardness of minerals within the ore. Finer grinding has

These ores are represented notably by the so-called porphyry-copper ores. (PDF) Grinding Kinetics Adjustment of Copper Ore Grinding. Comparison of dry and wet grinding process in an electromagnetic mill is presented in this paper. The research was conducted in a batch copper ore grinding. 12.3 Primary Copper Smelting. Mining produces ores with less than 1 percent copper.
12.3 Primary Copper Smelting
Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

EXTRACTION OF COPPER
Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper. Crashing and Grinding The ore is crushed then ground into powder. CONCENTRATION-Floatation process. The finely
Copper Ore - an overview | ScienceDirect Topics
The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.
