As free-milling and oxide ores become depleted, more complex polymetallic and refractory ores are being processed, coupled with increasing pressure for stricter environmental compliance. Recent years have also seen a steady reduction in mineral processing and metallurgy graduates and a gradual loss of older operating experience. A contribution to documenting current and future best practice in gold ore processing seems timely. The focus of this volume is on advances in current gold plant operation, from conception to closure; chapt 410 0$aDevelopments in mineral processing ;$v15. 606 $aGold ores$xResearch 606 $aOre-dressing$xResearch 615 0$aGold ores$xResearch. 615 0$aOre-dressing$xResearch. 676 $a669/.22 701 $aAdams$b Mike D$01825430 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911006643603321 996 $aAdvances in gold ore processing$94393102 997 $aUNINA
