The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site. Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite.
