For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

Gold ore is a type of ore that can be obtained by mining gold ore rocks, requiring a Mining level of 40 or higher, and granting 65 experience. Gold ore can be smelted into gold bars through the Smithing skill, requiring level 40 Smithing. Gold bars can then be crafted to make various pieces of jewellery.
In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. This is also true for operators processing large quantities of hard rock material. I've done up a web page on using Mercury to capture fine gold and you can view it here. (link to page)
A single piece of gold ore generally has very little actual gold content. Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material.
