The Treatment of Ore - Mount Morgan | .au

When the "syndicate" was formed in 1882 by the three Morgan brothers, Frederick, Thomas, and Edwin (Ned), together with three Rockhampton business men, William Knox D'Arcy (solicitor), Thomas Skarratt Hall (bank manager), and William Pattison (grazier), to treat the oxidised auriferous (gold-bearing) ore from the mountain top, it was thought that the gold could be recovered by amalgamation in ...

A Review on Novel Techniques for Chalcopyrite Ore Processing

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

Pegmatites and aplites: Their genetic and applied ore geology

Definition: The term "ore" is defined in the current study to describe a concentration of non-metallic, e.g., feldspar, or metallic minerals, e.g. spodumene, in pegmatitic rocks irrespective of its structure and position in the deposit which was or is currently mined for a profit.
