2021-9-14 · You can do batch leaching - but I would suggest you want closer to 24 hours of retention time. Any device that can add air to the tanks will work but keep in mind it has to have enough pressure to overcome the pressure of the slurry head. Small air compressors work fine but they are costly to run and are not typically meant for continuous duty.
