Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottle-roll tests of finely ground material are run.

  • 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 m) locked.
