The GlyCatTM process offers a simple and effective method to reduce cyanide consumption caused by the presence of copper in gold ores and concentrates. Reusable glycine is added to the leach to enable a 5-to-10-fold reduction in cyanide usage for the same copper feed concentration in order to yield similar gold extractions.

copper, which are also found in ore deposits of copper, can be converted into a soluble form by leaching, where the chemistry of the process is simple. Copper carbonates and oxides, are present mainly in the oxidation zone
Heap leach solution is irrigated over the ore and percolates by gravity through the ore to be collected at the base of the pad in a collection drainage system. As the solution passes through the ore various metals including copper (Cu) are dissolved from the ore into the passing leach solution (leachate).

Refractory copper ores (CROs) in central Africa contain copper minerals that are locked up in a micacious solid matrix or associated with carbonate, sulfide and phosphate minerals. Several researchers have reported that the recovery of copper from CRO material by an acid-leaching process is not economically feasible, due to the presence of excess gangue-acid-consuming minerals such as calcites

Heap leaching is considered to be an economical, cost-effective process to treat lean-grade ores. Its advantages compared to conventional flow sheets can be understood in terms of. 1. elimination of costly fine grinding and. 2. ability to treat even very lean-grade ores (e.g., 0.4%–0.5% for copper sulfides and 3–5 g/t for gold ores).
