equipment to recover gold without chemicals

Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available. The number 1 application for iCON i350 worldwide is Hard Rock. The 10-15 TPH capacity and the ability to recover fine, flat milled gold are ideal for iCON
