Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "The Quartz Operator's Handbook". Unavailable since 1871, this publication offers rare insights into ore milling operations during the late 19th century. Included are the fine details on early ore milling techniques by stamp mill, on gold recovery by amalgamation, chlorination and smelting, on the use of fire assays and blowpipes and other methods that early miners used to evaluate and process gold, silver, copper and other ores. Also included is a bonanza of information on the formation and exploration of ore deposits, mine venilation, early ore milling machinery, roasting and smelting ores and dozens of other metal mining topics.
