The cyanide control system was developed by Degussa Huels, who also supplied the online cyanide analyzer (potentiometric titration). The ore was mostly free-milling gold (90%) at a grade of 4.35 g/t, with 2.5–3.0% pyrite, 3.0% arsenopyrite, and a P90 of 74 μm. Initial plant throughput and retention time were 2155 t/d and 50 h

A maximum of 93% copper dissolution was obtained when the ore was treated with 90 kg Cl − /t ore, 40 d of repose time and 50 °C in flask leaching. Without any ore pretreatment, 53% copper dissolution was achieved. Using reactor leaching, an 85% copper dissolution was obtained using pretreatment stage.

The deposit at Gedabek is a copper–gold porphyry, comprising both oxide and sulphide ore mineralisation, which is being mined at the rate of about 1 million tons of ore per year. Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or …

Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.
