A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade.

Crushing and Grinding: Rock gold is often embedded in hard rock, and the rock first needs to be ground and broken to release the gold ore. Gravity separation: Similar to placer gold, rock gold can also be initially separated by gravity separation. This can be achieved using vibration tables, centrifuges, spiral chutes and other equipment. …

Pyrite has a higher specific gravity measuring 4.8-5.0, while gold weighs in at 19.3 g/cm3. Even though gold has a higher mass, pyrite's relative density exceeds that of gold due to the presence of sulfur in its molecular structure. So by volume, a piece of pyrite weighs more than the same volume of gold.
