SX1 maximises copper extraction using a high extractant concentration and high OA SX2 generates a low copper raffinate ( 0.5 g/l). Pilot-Plant Evaluation An eight-week, integrated pilot-plant campaign producing 24 kg/h cathode copper was carried out at AARL 4. The pilot plant treated 27 tons of CRO and 2.5 tons of Konkola copper concentrate (acid producing) and the oxide copper ore (acid consuming). Copper leached in the autoclave provides a conven-ient way of transferring acid from the sulfide circuit to the oxide circuit.

drosses. The pilot plant flowsheet is shown in Figure 2. Pilot-plant runs with both LIX65X and LIXsl have been carried out. Both reagents have been shown to operate successfully, hut adoption of LIw would reduce the size of the solvent extraction plant by a factor of ten due to this reagents much higher copper loading capacity. Solvent Extraction (SX) The configuration of the main solvent extraction circuit is 2 stages of extraction, 2 stages stripping and a single wash stage. The raffinate, which is not required for atmospheric leaching or for sulphate in the autoclave, is neutralized to pH 1.8 and the remaining copper is removed by a secondary extraction

Bluebird and Bagdad solvent extraction and electrowinning (SXEW) operations in Arizona in the late 1960s, the Tailings Leach Plant at Chingola, Zambia, became the first large-scale copper SX plant in the world, commissioned in 1974. Despite the equipment design now being outdated, this plant still continues to operate copper with five 9s (99.999 percent copper) quality. The A/E-SXEW pilot plant is designed to operate at low and intermittent flow rates for 6 months in order to obtain sufficient data for further process commercialization. This paper . outlines the successful piloting of solvent extraction process for copper recovery from ammonia

In the SX-EW plant, the copper-bearing acid solution from the collection pond is mixed with water and an organic solvent that preferentially binds to the copper ions. This mixture is allowed to settle and separate. The organic copper-rich portion floats to the top, and the metal-free portion falls to the bottom. This step is called This article compiles the results of a review of world copper solvent extraction (SX) plant practices and examines changes in operating practices in the last seven years as compared to previous world copper SX surveys in 1996 and 1999. Trends covered are fiber-reinforced plastic construction mixer box and settler designs, reverse flow settlers, and advanced mixer design. These changes have ...

Jan 01, 2016 Although the first large-scale application of copper recovery by solvent extraction took place in Zambia in the early 1970s, it is only in the last decade that this technology has become widely employed in this part of the world and is now a mainstay unit operation in copper hydrometallurgical flow sheets. Solvent extraction is a pivotal unit operation in many hydrometallurgical circuits, essential to facilitating flowsheet optimization and ensuring final product purity. Although it has been widely used in the copper and uranium industries for many decades, its use in other applicationsespecially those of
