Feb 10, 2021 "Since filing its bankable feasibility study, Nouveau Monde has invested time and effort to meticulously plan mining and environmental engineering, master the ore metallurgical process to reach 97% purity after simple flotation, de-risk its operation through its demonstration plant, and actively engage with the local community of St-Michel-des[email protected]
A bio-oxidation plant in Ghana, constructed during 1994, has a capacity of 720 tons of gold-bearing concentrate per day. Because the price of gold has risen many mineral companies now take a second look at deposits that were once considered uneconomical. Many of these deposits are refractory and tend to resist cyanidation.

The Kakula 2020 FS highlights that a mining rate of 6 Mtpa yields an after-tax NPV8% of US$5.5 billion and IRR of 77% at a long-term copper price of US$3.10/lb, rising to US$8.4 billion and IRR of
Hydrometallurgical treatment of Zn sulphide ore involves separation of Zn from Fe, as most Zn processing concentrates contain 5%–12% Fe. Processes involving the formation of jarosite remove Fe from acidic zinc sulphate solutions prior to Zn electrolysis (Dutrizac and Kaiman, 1976; Arslan and Arslan, 2003).
Oct 23, 2020 — Gold concentration usually consists of gravity separation, flotation, Recently, the recovery of gold using gravity methods has gained attention because of low cost processes are used for gold ore beneficiation: cyanidation, flotation the ore sample indicated that there was no selectivity in terms of zinc

The gold market has undergone significant change over the past two decades, becoming larger, stronger and more widely understood. The World Gold Council has been a key player in many of the initiatives that have driven that change, such as the liberalisation of the gold market in China and the rapid rise of demand in the East.
Mar 31, 2021 Total underground mine production and sales, on a 100% basis, was 616,341 payable silver ounces, 1,029 payable gold ounces, 163 tonnes of lead and 224 tonnes of zinc.
