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 ...

MINERAL AND ROCK RESOURCES. LECTURE NOTES . I. Introduction . Eight elements (O, Si, Al, Fe, Mg, Ca, Na, and K) make up 98% of the earth's crust. Many important elements are found, on average, in the crust in very small amounts (ppm ppb) Finding these elements in high concentrations is the exception and requires unusual geologic processes.
