Solvent Extraction Studies of Copper from a Heap Leach Liquor Using Mextral 5640H

In this study the extractive capability of Mextral 5640H was investigated for extraction copper from a heap leach liquor. regard, influence parameters such as pH (0.2–2.8), extractant concentration in kerosene diluent (2.5%–10% v/v), temperature (25–70 °C), contact time (0–300 s), stirring speed (100–1200 rpm), phase ratio (O/A) (0.6–1.8) and Cu initial (0.5–2 g/L) liquor were examined optimized. The findings demonstrated that had very high efficiency selectivity leachate. 98.17% Cu, with less than 0.5% Fe Mn, extracted at 1.6, 10% (v/v) concentration, ambient (25 400 rpm speed, 2 min an O/A 1:1. Under equilibrium conditions it found one mol is by 7 5640H. Additionally, analysis using McCabe–Thiele diagram suggests two-stage to reach maximum (99.5%) leachate operational condition industrial mixer-settlers. Furthermore, thermodynamic conducted, measured values ΔH = 15.13 kJ/mol, ΔG −6.95 kJ/mol ΔS 74.10 J/mol/K indicate endothermic, spontaneous nature affinity extraction.
