Free-Milling Gold Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold

The objective of milling gold ores is to extract the gold for the highest financial return. To recover the maximum amount of gold, the ore must be finely ground in order to liberate the gold particles for gravity separation and/or chemical extraction.

Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate ...

Treatment of lead and zinc ores begins with milling. Milling is a multi-stage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill.
