Can you explain recovery and recovery rates? Say I am jigging mineral, I get a 60% recovery rate. feed specific gravity is 3.8, final product gravity is 4.2. If I lower my recovery rate to 50%, what will happen? maintain final specific gravity, but increase quantity? Increased quantity, but decreased specific gravity? Thank you for your help
