This has led to a large number of copper ore and concentrates exports to China, as Fig. 4 and Table 3 shows. In 2014, the copper ore and concentrates imported to China from various countries in the world was 11806.97 kt. However, the export number was only 0.82 kt. The trade value of China's imports had reached 21464 million dollars.

2014年7月17日 However, concentration methods such as froth floatation separate the copper minerals from the waste rock for more tricky ores, such as sulfide ores. The sulfide ore is then roasted or smelted into a purer copper concentrate called a slab. Finally, the copper slab undergoes electrolysis, resulting in 99.99% pure copper cathode slabs.

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
Read More2020年7月6日 With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the
