400 rpm stirring rate. The leaching experiments were carried out for 4 h and samples were taken at the designated time. Acid concentration of 0.5 M, 1 M, 1.5 M, and 2 M was used, while the temperature was varied from 25 ºC, 45 ºC, 65 ºC, and 75 ºC to 90 ºC. The results show that acid concentration does not aect La, Ce, and Y recovery.

Leaching (chemistry) - Wikipedia
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 concentration, distribution, nature, and size.

Leaching. Leaching is a chemical process of concentration of ore. Here the ore dissolves in a chemical solution. The minerals will react and dissolve leaving behind the impurities only which filter out. And then the metal will be obtained from the chemical solution. Let us now take a look at an example of how we obtain Aluminium by leaching.

The economic upper limit to extract concentration is 70% oil. Ravenscroft [Ind. Eng. Chem. 28, (1934)] measured the relation between the concentration of oil in the solution, y, and the entrainment or occlusion of solution by the solid phase, K lb solution/lb dry solid, which is represented by the equation K = 0.19 + 0.126 y + 0.810 y 2.
