Advantages of ball mill discharge to leach tank

overflow type ball millthe structure of overflow type ball mill is roughly the same as grid type ball mill, which has no discharge grid at the discharging end of the cylinder. moreover, inner surface of the hollow shaft is set with the anti-spiral blade, which can make the overflow small ball and the coarse ore blocks in the slurry back to the mill. overflow vs grate discharge ball or millthe discharge end of the grate discharge ball mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. the discharge grates are designed to run clean and free of any blinding or choking. introduction to cyanide gold mininga slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. following this leaching process the slurry passes through adsorption tanks containing carbon granules which adsorb the gold and silver. this process removes. >90% of the gold and >70% of the silver. 300 tpd gold and silver plant with merrill croweball 6x9 @ 125 hp w/ feed chute. ball mill discharge chute. sala vasa g 234 sump pump @ 7.5 hp. sizing screen 3x3x3. thickener reed pump 3x3 srl @ 10 hp. leaching circuit: #1 leach tank 18 ft. dia. x 22 ft. high c/w agitators, aeration 25 hp motor. #2 leach tank 18 ft. dia. x 22 ft. high c/w agitators, aeration 25 hp motor. overflow type ball millthe structure of overflow type ball mill is roughly the same as grid type ball mill, which has no discharge grid at the discharging end of the cylinder. moreover, inner surface of the hollow shaft is set with the anti-spiral blade, which can make the overflow small ball and the coarse ore blocks in the slurry back to the mill. cyanide optimization and the use of ozone for wad cyanide cyanide optimization and the use of ozone for wad cyanide ball mill sag mill discharge screens sump - pre-oxidation in tk 1 leach tank prior to adding appendix atransfers the discharge from the feeder belts to the ball mill belt feed. 7. grinding each primary grinding circuit consists of a ball mill which is operated in closed circuit with a spiral classifier. the grinding circuits utilize ]0 feet by 66 inch hardinge conical ball mills. the ball charge in each mill is approximately 22 tons.
