At this time, the stamps are the heaviest in use in the country. The ore is taken from the mine and crushed to a suitable size in an Allis-Chalmers gyratory crusher, carried to the storage bin in an ore car. Eventually, a 4 ton ore car is hauled up a tramway and ore stored in a second bin at the mill. This bin feeds direct to the stamps."

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.

We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.

The purpose of this data-file is to tabulate typical cost estimates for crushing-grinding processes, which consume 1-2% of all the energy in the world and 20-50% of the energy in some mining processes. Our numbers are shown per ton of ore, so clearly lower ore grades translate into higher costs per unit of extracted material ().Energy economics.
