As the most important index in measuring the value of ore, ore grade is also a criterion for evaluating whether a mine has mining value. At present, most methods of ore grade detection are divided into three types [1], [2], [3]: chemical titration method, flame atomic absorption method, and electrolysis method.These methods are highly accurate but have a …

Burns and Grimes (1986) reported pre-concentration of a copper ore by screening at the Bougainville copper plant operation. ... By contrast with the size-related waste rejection through screening, ore sorters use sensors to determine grade related physical properties. In essence, ore sorters have a better opportunity to minimise value loss ...

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.
