Agitation and column leaching studies of oxidised copper

2017-9-1  2.3. Agitation leaching. Batch agitation leaching tests were performed using a 1 L polypropylene beaker provided with a pH-temperature electrode to determine the maximum solubilisation yield of cobalt and copper and the proportion of trivalent cobalt in the ore.A total of 200 mL of 75 g/L H 2 SO 4 aqueous solution was placed in the beaker and a weighted ore sample (15% (w/v)) was added.

Copper Dump Leaching and Management Practices That

Vat leaching is used to extract copper from crushed, nonporous, oxide ore in large tanks or vats. Agitation leaching involves the rapid leaching of ore concentrate or roaster calcine in agitated tanks. Vat and agitation leaching are generally more rapid, more efficient, and much more costly than dump leaching.

Two-Stage Agitation Leaching of Old Flotation Tailings

Copper-zinc concentrate contained 23.8% of iron, 16% of copper, and 5.3% of zinc. Agitation leaching of old flotation tailings with distilled water and sulfuric acid solutions (of 0.5 to 10% H 2 SO 4) for 3 h at pulp density of 20% made it possible to extract of 26 to 34% and of 58 to 70% of copper and zinc, respectively.
