Copper-processing technologies: Growing global copper

2023年2月17日 The trend of declining copper head grades is well established and unlikely to be reversed. Similarly, oxide ore bodies, which do not require concentrators and can be processed through less capital-intensive routes, are being exhausted. The mining industry has responded to these challenges by processing ever-increasing volumes of sulfide ores.
