recovery in copper mining

2015-7-23  The recovery of copper through passive in-situ methods such as those used at Bingham Canyon during the 1880s eventually led to a more active approach, where water from underground mine sumps was applied to the ores and the resulting copper-bearing solutions collected and the copper recovered. One of the earliest attempts that employed this technique occurred in the nci Mining District of Arizona at the Medler mine

Excelsior Mining Corp In-Situ Recovery

2021-7-30  The optimal conditions to use In-Situ Recovery for copper mining follow a few guidelines. Firstly, the host rock needs to be fractured enough to allow for the solution to permeate through and dissolve the copper resource. The more fractured the rock, the more surface area there will be for the copper to be dissolved.

Biomining: metal recovery from ores with

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

2017-4-5  At Miami, operations in 13 completed stopes or blocks resulted in the recovery of 2.4 percent more copper than had been estimated previously, but 15.15 percent more tonnage was drawn, the average grade being 88.93 percent of the calculated grade. Careful regulation of drawing is essential to obtain minimum dilution and maximum recovery.

2014-9-8  number of studies have been conducted on the hydrometallurgical recovery of base metals from various copper-containing slags. Thus, the lixiviants investigated include sulphuric acid (Banza et al., 2002), ferric chloride (Anand et al., 1980), chlorine (Herreros et al., 1998), aqueous sulphur dioxide (Gbor et al., 2000), hydrogen peroxide (Banza et al., 2002), mixed nitric-sulphuric acid (Xie et al., 2005), potassium dichromate (Altundogan et al., 2004) and sodium chlorate (Yang et al., 2010). In addition, research has been done into pressure leaching (Anand et al., 1983, Papangelakis and Perederiy, 2009), bioleaching (Carranza et al., 2009, Kaksonen et al., 2011) and the effect of ultrasound on acid leaching (Bese, 2007).

What is InSitu Recovery? Environmental Copper

What is. InSitu Recovery Mining? Metals (Copper, Gold etc) are recovered ‘In Situ’ by firstly dissolving the commodity in place and then extracting them using a system of injection and extraction bores or wells. Most times ISR accelerates what is already happening naturally within the bedrock and water table.

Copper and Cyanide Recovery in Cyanidation Effluents

2016-2-26  Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is pro-posed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as the precipitator, and sulfuric acid for pH control. Results show that pH value has a significant effect on copper cyanide removal efficiency, and it was determined the optimal pH range to be 2.5 3. At this pH value, the copper cyanide removal efficiency achieved was up to 97% and 99%, when copper concentration in the influent was 636 and 900 ppm. respectively. In this process (sulphidiza-tion-acidification-thickening-HCN recycling), the cyanide associated with copper cyanide complexes, is re-leased as HCN gas under weakly acidic conditions, allowing it to be recycled back to the cyanidation process as free cyanide.
