The use of gold mine tailings in the production of building blocks / bricks, is examined in this study The tailings used in the study were characterized by having an optimum As a result of the metal recovery process, a total of 1,559 Mt of mill tailings were produced and deposited in a bay of the adjacent Lake Kirkkojärvi (Fig 1) Most of the tailings were drained in an impoundment restricted by a dam structure (184 ha), and additionally, through the end of the mining activity, tailings were also discardedRevalorization of Haveri AuCu mine tailings (SW Finland) for
The process operated for 10 years (Tempel 2003; Roberto 2017) treating 800,000 tonnes per year of refractory gold ore and producing an estimated 500,000 oz of gold over 10 years The patented Newmont process trademarked as BioPro™ was applied to refractory ore in an “on/off” leach pad cycle that required removal of the biooxidized The head grade of copper in the ore is 1–2% and the oxidation state is ~60% [ 26 ] The decision to use the combined technology for processing ores with the ultimate recovery of copper into a bulk concentrate (~90%), its low copper content (~5–6% copper), and the decrease in copper loss with tailings was taken after numerous testsCurrent Status of CopperOre Processing: A Review

The aim of this work was to make an estimate of the remaining metal resources of the Haveri tailings (SW Finland) that were deposited for 60 years ago We used existing databases (Cu, Zn, Ni, CoGold, silver, lead, zinc, sulphur, indium, gallium, cadmium, germanium, selenium, tellurium, and other associated elements recovered from Chinese copper ore during the processing and smelting process account for 44% of the total output value of the raw materials; associated gold accounts for more than 35% of China’s gold Progress, Challenges, and Perspectives of Bioleaching for Recovering
This study presents the novel idea of a cyanidefree leaching method, ie, glycineammonia leaching in the presence of permanganate, to treat a lowgrade and copperbearing gold tailing Ammonia played a key role as a pH modifier, lixiviant and potential catalyst (as cupric ammine) in this study Replacing ammonia with other pH For the purpose of this paper, gold mining residues with a particle size of approximately 70–80% finer than 74 μm are defined as slime and residues grading 10–20% finer than 74 μm as sand The first phase of the retreatment process is to obtain credible information with the sampling programme (and the subsequent metallurgical testwork) aA practical guide to retreatment of gold processing residues
