The Enrichment of Copper Sulfide Ores

Mining historian Kerby Jackson introduces us to a classic mining publication on copper sulfide ores by J.D. Clark. First published in 1913, it has been unavailable for over a century. Topics include the definition and types of ore enrichment, the oxidation of copper ores, the precipitation of metallic sulfides. Also included are the results of dozens of lab experiments pertaining to the enrichment of sulfide ores that will be of interest to the practical hard rock mine operator in his efforts to release the metallic bounty from his mine's ore. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.
