The largest ancient Chinese mines
Posted 24 June 2010 - 06:56 AM
If anything, precious metal yields in the Han period must have been lower still: gold was mostly derived from placer deposits while underground mining of gold, in so far as it occurred at all, appears to have been rare: few of the known historical gold mines in China were active in that period.
Silver was virtually. unknown in central China prior to the Warring States period. This metal is generally rare in central China and concentrated in the far south, and the earliest evidence for the cupellation of argentiferous sulphide ores comes from the Tang period.
This leaves tin, zinc and particularly copper as main fields of activity of early Chinese underground mining, doesn't it?
