Ammonium sulfate leaching

Ammonium sulfate leaching is a process used to extract valuable metals from ores or waste materials. It involves treating the material with an aqueous solution of ammonium sulfate, which reacts with the metal-containing compounds to form soluble complexes. This allows the metals, like copper or zinc, to dissolve into the solution. The metal-rich solution can then be separated from the remaining solids and processed further to recover the pure metals. This method is environmentally friendly and efficient, often used in mining and waste treatment to safely recover valuable metals from complex or low-grade sources.
