加拿大普莱瑟多姆有限公司拥有并经营坎贝尔矿山和选厂。坎贝尔矿山和选厂位于加拿大安大略西北角的巴尔默汤(Balmer-town)。矿山处理能力为1300t/d。在过去的3年中,矿山的金产量为9.3t/a。重选回路的改造使重选回收率增加10%～15%。坎贝尔选厂的原矿品位较高,平均为18.5g/t。在过去的7年中,原矿品位平均约为20g/t。1994年以前,选厂采用的是普通矿物跳汰和摇床联合流程。1994年5月,选厂决定购买两台Knelson CD 760mm选矿机,以替代现有跳汰机,使重选精矿回收率提高15%。跳汰机的重选回收率平均为30%～35%。预计采用Knelson选矿机重选回收率可提高到约50%。
Canada Plessedom Co., Ltd. owns and operates Campbell Mining and dressing plant. The Campbell mine and mill is located in Balmer-town, northwest corner of Ontario, Canada. Mine processing capacity of 1300t / d. In the past three years, the mine’s gold production was 9.3t / a. Re-election of the transformation of the re-election so that the recovery rate increased by 10% to 15%. Campbell processing plant ore grade higher, with an average of 18.5g / t. In the past seven years, the ore grade averaged about 20g / t. Prior to 1994, the mill used a common mineral jig and shaker joint process. In May 1994, the mill decided to purchase two Knelson CD 760mm concentrators to replace the existing jig and increase the recovery of reject concentrates by 15%. The jig recycling rate averaged 30% ~ 35%. It is estimated that the reclamation rate will increase to about 50% with Knelson concentrator.
