vat leaching of copper oxide ore - hydrometallurgy

Hi We are planning a VAT leaching for HMS rejects of copper oxide ore. We are stuck at design and would value inputs. We are planning for a 5000 tons holding capacity for the VAT and feed grade is 1% copper. Size of feed 100% passing 20 mm. Would there be any channeling effect in the VAT as we are p

us4039405a - leaching copper ores and solvent extraction

This invention relates to a process whereby recovery of copper from copper ores using leaching and solvent extraction techniques can be increased. The process generally comprises leaching to obtain a pregnant leach liquor, washing ore residues with an extra quantity of water to obtain extra dissolved copper values, recovering said copper values, combining the extra wash water with the pregnant

pressure cementation process for recovery of copper from

pressure cementation process for recovery of copper from

Conventional cementation technology dictates that a copper leaching operation be carefully controlled to produce an influent solution to the precipitator having a pH in a range of about 1.5 to 3.0. Solutions having a pH below about 1.5 contain such excessive amounts of free acid that iron consumption becomes an obvious economic deterrent

process for recovery of copper - inspiration consolidated

What is claimed is: 1. A process for the leaching and recovery of copper values from copper-containing material which comprises: vat leaching sulfidic copper ore with an aqueous acidic ferric sulfate leach solution containing at least 10 gpl ferric ion to form a copper-pregnant leach solution containing substantially less than 10 gpl ferric ion and a corresponding increase in ferrous ion

heap leaching gold and silver ores

heap leaching gold and silver ores

Vat leaching has been widely used by the copper industry on higher grade copper ores but has been used in only a few small operations on that size gold or silver ores. However, such a plant should be considered for a modest tonnage of a few million tons, 3 to 7 g per mt (0.10 to 0.20 oz per st), of Carlin-type leachable ores crushed to 9 mm

Jan 01, 2016 · 1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value
