Webleaching in (0.25, 0.5, 1 and 2 (mol.L-1)) sulfuric acid solutions. The subsequent leaching was performed in the optimized acid concentrations at temperatures of (25, 45, 65 and 85 °C) for (0.5, 1, 1.5 and 2 hour) at each temperature. A variable speed stirrer operated at a speed of 100rpm was maintained during in all leaching experiments at 1MPa. Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as c…
