Principal processing flowsheet of copper–brass

To recover copper from the formed solution, liquid extraction with the solution of 0.34 mol/L DX-510A in kerosene is applied. Copper ions are recovered from the organic phase by reextraction with the 2.0 mol/L sulfuric acid solution. Cathodic copper is isolated from the sulfuric acid electrolyte at the current density of 1.5–2.0 A/dm 2. The advantages of the proposed flowsheet are an increase in environmental

Copper Example. In the case of oxide copper ore, a heap leaching pad will dissolve a dilute copper sulfate solution in a weak sulfuric acid solution. This pregnant leach solution (PLS) is pumped to an extraction mixer settler where it is mixed with the organic phase (a kerosene hosted extractant). The copper transfers to the organic phase, and the aqueous phase (now called raffinate) is pumped back to the heap to recover more copper.

Principal processing flowsheet of copper–brass

Abstract. The process flowsheet of dusty wastes forming during metallurgical brass production with the use of two-stage leaching is proposed. The production solution, which contains the main amount of zinc ions (0.46 mol/L) and a small amount of copper ions (less than 0.02 mol/L) is formed at the first stage during the dust dissolution with the 0.5 mol/L sulfuric acid solution.
