2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

The proposed model has been applied to the optimization of the production process of a stage in the Huogeqi Copper Mine. The optimization results provide a set of Pareto-optimal solutions that can meet varying needs of decision makers. ... The first is the optimization of metal mine production in the beneficiation process [7,8,9,10,11 ...

Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The … See more

In the paper, a new technology was developed to improve the beneficiation of copper and iron components from copper slag, by modifying the molten slag to promote the mineralization of valuable minerals and to induce the growth of mineral grains. Various parameters, including binary basicity, dosage of compound additive, modification …

The depletion methods of copper slag mainly include beneficiation method, leaching method, and fire method . ... Besides, it has a strong ability to process copper slag and is easy to realize industrialization. Therefore, it is a promising new choice for the future use of copper slag as a resource and high-value utilization.

The mining and beneficiation process of one tonne copper sulfide ore is listed as a basic functional unit. 0.03 tonnes copper concentrate, 0.14 tonnes high-sulfur concentrate, and 0.02 tonnes low-sulfur concentrate obtained from one tonne raw ore were performed based on the economic allocation principle.
