Copper Leaching Method Metallurgist & Mineral

At the Steptoe mill, in Nevada, a small leaching annex is treating oxidized copper ore in conjunction with flue dust at a cost of $008 per pound copper recovered The actual cost of copper produced by leaching methods is, however, not of so much importance as the fact that ore may be handled in this manner which is not amenable to reduction by any other processJust as dump leaching has allowed for recovery of supplemental copper from stockpiled waste rock, ISL could represent an opportunity for lowcost recovery of copper from low grade material that has not been excavated (Bartlett, 1998) Targeted areas may include underground workings and pits, both with and without fragmentationIn situ leaching of copper: Challenges and futureUpon saturating the macrofractures, these act as a network of distributed sources and sinks for flow of solution into and out of the rock matrix Since copper is disseminated throughout the rock matrix, understanding and exploiting permeability conditions are essential for successful leaching operations in both the matrix and fracture systemISL InSitu Copper Leaching

Copper Mining and Extraction Sulfide Ores

They occur in both sedimentary and igneous rocks The outer 10 km of the crust contains 33 g of copper for every tonne of rock This is not enough to make it commercially viable to extract the rock Copper mines are only set up where there is more than 5 kg of copper per tonne of rockGenerally, copper leaching requires a supply of both ferric ions to oxidize the sulfides and acid to dissolve copper oxides and to keep dissolved material in solution Continued copper leachingWaste Dump Leaching Copperout of the leaching process was very simple We weighed out an amount of ore into a beaker On this beaker was then placed the date, time, the amount of are taken, the amount and kind ·of solution taken, and it was set away until the leach was finished The solution wasLeaching copper tailings

Modeling In Situ Copper Leaching in an Unsaturated

copper oxide ore is a heterogeneous, unsaturated, and fractured medium in which the permeability is dominated by a network of macrofractures, defining blocks of rock of various sizes Upon saturating the macrofractures, these act as a network of distributed sources and sinks for flow of solution into and out of the rock matrix Since copperJust as dump leaching has allowed for recovery of supplemental copper from stockpiled waste rock, ISL could represent an opportunity for lowcost recovery of copper from low grade material that has not been excavated (Bartlett, 1998) Targeted areas may include underground workings and pits, both with and without fragmentationIn situ leaching of copper: Challenges and futureThe heap leaching unit corresponds to a copper ore heap of 456,000 m 2, with a grade of 15 % of copper Also, the time horizon corresponds to 360 days and copper price was considered to change from 2,000 to 12,000 $/tonCopper Ore an overview | ScienceDirect Topics

Leaching behaviour of copper slag, construction and

When the leaching time is 150 h, the influence of ore particle size on the leaching rate is so small that it could be neglected When leaching time is over 180 h, the copper leaching rate reachesInplace leaching is employed to extract copper from broken low grade rock in and overlying a now abandoned copper mine As with dump leaching, the cycle duration is in years There is thus time for the oxidation and dissolution of sulfide minerals Of the leaching methods currently employed, only dump and inplace leachingXA04N0873 OSTIGOVElevated metal leaching is associated with acidic drainage due to high metal solubility and sulphide weathering rates under acidic conditions For many rock types/environmental conditions, metal leaching will only be significant if drainage pH drops below 55 or 6GUIDELINES FOR METAL LEACHING British Columbia
