**Pressure leaching and autoclaves in mineral processing: how the process works and what the equipment must handle**
Pressure leaching dissolves or transforms target minerals inside a sealed vessel held above the normal boiling point of the solution. Raising temperature accelerates reactions that run too slowly at atmospheric conditions. Raising pressure keeps the aqueous phase liquid and forces reactant gas into solution. The vessel that provides those conditions is an autoclave. Pressure and … Read more
