1st October 1892. Mt. Morgan is located in Queensland, Australia and was the largest gold mine in the world at its peak in the early 1900s. Over its lifespan, the mine yielded approximately 262 metric tons of gold, 37 metric tons of silver and 387,000 metric tons of copper. As with many older mining projects, the legacy of Mt. Morgan is a large hole in the ground, waste and tailings stockpiles that produce

The Process Mineralogy Of Gold The Classification Of Ore

The Process Mineralogy Of Gold The Classification Of Ore

Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic solid solution gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold 10 m locked in sulfides.
