Leaching is a hydrometallurgical method that permits the beneficiation of gold ores from deposits which would else be uneconomic because of their fine gold distribution or their relatively low gold gradIn order to perform cementation tests 100 ml of copper ore was dissolved in the solution and added up to a 250 ml beaker and after regulating pH the temperature will be adjusted by the hotplate After these steps iron powder will be added up to the solution in order to study the test
