The effect of extractant concentration on copper extraction was studied by contacting sulphate solutions containing 0.1M copper(II) at an initial pH value of 3.95 with LIX® 984N at concentrations from 5–25% (v/v) . As shown in Figure 3, copper extraction increases from 2.8 g/L (44%) to 6.27 g/LSolvent extraction of copper from acidic sulphate solutions was carried out using the new oxime extractant, MOC 45 diluted in distilled kerosene.Increase of aqueous phase pH and extractant concentration in the organic phase increases the percentage extraction of metal.

Copper Sulfate is a nutrient supplement and processing aid most often used in the pentahydrate form. This form occurs as large, deep blue or ultramarine, triclinic crystals, as blue granules, or as a light blue powder. The ingredient is prepared by the reaction of sulfuric acid with cupric oxide or with copper metal. May be used in infant formula.Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.

Metalcess provides copper ore leaching, PLS solvent extraction and copper electro-winning.Specially treating copper sulfide ore by pressure leaching to get elemental S instead of H2SO4 acid. Copper Sulphate Crystallization and MVRMost pins from e-scrap is gold plated brass, if you would get a clean copper from that feedstock you need to add a lot of copper sulphate to compensate for the zinc that goes into solution. But if you can get your cell to plate out zinc and copper in brass proportions than you could run it for longer times without worrying about the electrolyte.

Liquid-liquid extraction and separation of copper(II) and - extraction process of copper

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 stage.for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and electrowinning.

The sulfate analysis was corrected for the amount of sulfate present as CuSO4 so that the ordinates of figures 1 and 2 show the ratio of copper to solvent sulfate in the solution. As figure 1 indicates, the solubility of CuSO4 in pure H2SO4 is relatively low, but increases rapidly as the (NH4)2SO4 content of the solvent increases.Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction SX and electro-winning EW. It can produce either copper cathode or copper sulphate crystal.
