Genesis and mineralization of gold-bearing quartz

11/10/2012  Gold-bearing quartz veins of the Taihua Group consisting of Archean metavolcanic rocks are a main gold deposit type in the Xiao Qinling area, one of the three biggest gold production areas in China. The quartz veins experienced strong alteration characterized by a typical mesothermal hydrothermal altered mineral assemblage. The grade of gold is affected by the contents of sulphides, e.g. galena, pyrite and chalcopyrite. Results of minor elements analysis for the of gold-bearing ...

mining methods for gold in quartz vein

Quartz Reef Mining, Mining Techniques, Surface Mining ... Quartz Reef Mining. Primary gold typically happens in quartz veins. The removal of gold ore from these tough quartz veins was traditionally referred to as quartz reef mining. A Prussian engineer, Jacob Brache was the foremost to feel that quartz reefs may have even more gold than alluvial fields.

Gold in Quartz - ICMJ's Prospecting and Mining

Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material. The gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz. The gold fills cracks and spaces in the quartz as the ascending gold-bearing solutions infiltrate the existing quartz vein
