Re-processing of "old" residue tailings has proved to be a profitable business for several operations, usually when incorporated into an existing facility to supplement declining ore arisings. These resources often prove to be a source of "cheap gold" since the high mining and feed preparation costs have already been incurred and only ...
Phase 1 involves upgrading the Driefontein 2 plant to process tailings from the Driefontein 5 dump at a rate of between 400 000 and 600 000 tpm and depositing the residue on the Driefontein 4 tailings dam. First production is expected in the first quarter of 2019, adding up to 120 kg or 3 800 oz of gold a month to DRDGOLD's production profile.

Konstantin Vadimovich Fedotov3. ... grinding of gravity tailings, the choice of the optimal consumption of butyl xanthate, and the study of the kinetics of flotation were carried out. At the final stage of
The Arequipa region has the third largest mining industry in Peru, producing 19.5 % of the country's annual gold in 2022 (Vera Gargurevich et al., 2023).Small-scale gold processing facilities (ore capacities up to 350 metric tons per day) play a large role in the industry, accounting for 40 % of the Arequipa region's gold production, with medium- (ore capacities of 350–5000 …
The contradiction between supply and demand of gold resources in China has always existed, and the proportion of recovery gold in the gold total supply is increasing yearly. Many gold-bearing tailings are produced in the mining, dressing and smelting process of gold-bearing minerals, and they contain gold, silver and other valuable metals. This paper analyzes …

The experiments involved adding specific quantities of cyanide and adjusting the pulp density of the gold tailings slurry. The process was carried out for 12 h at ambient temperature with an agitation rate of 450 rpm. The pH was maintained between 10.5 and 11.5 using NaOH. Oxygen was fed into the reactor at a flow rate of 10 mL/min to ensure ...
2. Flotation. Flotation is a process that separates valuable minerals from the rest of the ore using chemicals and air bubbles. The tailings are mixed with water and reagents, which cause the gold ...
The facility will reprocess the ground rock, known as tailings, from which gold was previously extracted in the Golden Sunlight mills. The focus will be on removing and concentrating sulfur (iron pyrite) to be sold to and used in gold production by Barrick operated and majority owned Nevada Gold Mines, the largest gold producing complex in the ...
EnviroGold Global Ltd, a clean technology company accelerating the world's transition to a circular-resource economy through the production of metals without mining, has agreed to commercial terms with Hellyer Gold Mines Pty Ltd (HGM) to reprocess the tailings owned by HGM (the Hellyer tailings reprocessing project) at the Hellyer Gold Mine, Tasmania, …
Inferior extraction techniques, combined with plenty of available high ore grade resources have historically made processing lower grade ores and tailings uneconomical and a low priority. ... Pan African Resources is also working on a gold tailings retreatment project in South Africa. The project intends to retreat old tailings at a rate of one ...
ESGold Corp (CSE: ESAU, OTC: SEKZF) has partnered with Dundee Sustainable Technologies to test tailings from the Montauban Project using Dundee's proprietary CLEVR Process.
