Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold.

In assessing the economic benefit of the extra processing that needs to be done to improve recovery from refractory or partially refractory ores, it is always important to consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.

Escondida copper, gold and silver production. Production at the mine was cut back during the period 2003 on account of the weak world market conditions for copper. The partners in the project decided to mine lower-grade ores while maintaining the concentrator throughput, thus reducing the impact on per-ton-treated costs.

With other surface stockpiled ore averaging 0.12% U 3 O 8 there is enough to last to 2020 if market conditions are favourable, or at least to 2016 when underground mining is planned to commence. However, annual production diminished from 2012 as progressively lower grade material is processed at a constant mill rate of about 2.4 Mt/yr.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
