This will reduce the volume of feed and increase the percentage of gold that you recover. iCON Gold Recovery uses a 2 step process; classification and concentration.

Understanding Vacuum and Vacuum Measurement

Low Vacuum – also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum – is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance ...
