Click for details2021-8-12 · Free-milling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation
Click for detailsOre is defined as “a naturally occurring mineral containing a valuable constituent (as metal) for which it is mined and worked”. In other word, ore is the most basic raw form of a mineral, which requires additional processing for the valuable minerals (gold) to be removed.

Click for detailsThe 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
