  • Ore Mineral - an overview | ScienceDirect Topics

    Often there are practical economic constraints in processing ores that may only be revealed by very careful microscopic study of the paragenesis. For example, some hydrothermal gold ores contain native gold or electrum encapsulated in later silica, making grinding and processing to release the gold much more difficult and expensive.

  • The process mineralogy of gold: The classification of ore

    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 µm) locked

  • Photos of gold ores, quartz, telluride gold ore and gold

    The fourth class of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type. They are often low in grade but large.
