using ballmillsto extract rawgoldfrom ores

Jun 14, 2018 · Using Ball Mills to Extract Raw Gold from Ores. Placer mining and lode mining are very different. Whereas placer gold has been released from within the rock and is generally free from any significant matrix, lode gold presents different challenges. While gold may be present in ore, it must somehow be released for proper extraction
