拉(La)金矿多洋(Do yon)选矿厂位于加拿大魁北克省的西北部,在鲁安—诺兰达(Rouyn-Noranda)以东约35公里、瓦勒多(Vald′or)以西85公里处.该金矿由拉克(Lac)矿物有限公司和坎比奥尔公司(Co-mbior Inc.)联合投资,并由拉克矿物有限公司经营.至1987年2月的生产统计数字,已处理矿石640万吨,平均金品位为5.8克/吨.埋深在400米以上的现有探明矿石储量为990万吨,金品位为5.7克/吨.在这水平以下,预计还有矿体,储量还将会有所增加.该矿由二个露天矿和二个地下矿组成,每天产出矿石量约为3600吨,平均金品位为6克/吨.目前矿石在多洋选矿厂每天处理1400吨,在拉克公司的东马拉蒂克(East Malartio)选矿厂每天处理1950吨.也有一部分矿石间断地送往拉克公司莱斯·特拉茵斯·奥里弗勒斯(Les Terraines Auriferes)选矿厂和诺兰达公司的霍纳(Horne)分公司的选矿厂处理.拉金矿多洋选矿厂正在扩建和改造.扩建后选矿厂处理能力为3000吨/日,扩建内容包括:原有破、磨回路改造为半自磨磨矿回路;原有的洗涤过滤车间改造成炭浆法金回收车间,由于采用现代技术,可降低生产成本(磨矿和运输费用)和提高回收率,从而使该项目可获得经济效益.
The La gold mine The Doon concentrator is located in the northwestern part of Quebec, Canada, about 35 kilometers east of Rouyn-Noranda and 85 meters west of Vald’or Km, a joint venture between Lac Minerals Co Ltd and Co-mbior Inc. and operated by Rak Minerals Ltd. Production statistics up to February 1987 have been processed The ore is 6.4 million tonnes with an average gold grade of 5.8 g / t and the existing proven ore reserves at a depth of 400 m are 9.9 million tonnes with a gold grade of 5.7 g / t. Below this level, , The reserves will also be increased.The mine consists of two open pit mines and two underground mines, the daily output of about 3600 tons of ore, the average gold grade of 6 grams / ton.Current ore ore processing plant in the daily Processing 1,400 tons and processing 1,950 tons per day at the company’s East Malartio concentrator in Rak Company Some of the ore was also intermittently sent to Rak company Les Terraines Auriferes ) Beneficiation plant and the Horone branch of Nolander Corp. The Lajin Gold Mine is being expanded and changed .Expanding concentrator processing capacity of 3000 tons / day, the expansion include: the original broken, grinding circuit transformed into semi-self-grinding grinding circuit; the original washing and filtration workshop into a carbon gold recovery workshop, the use of modern Technology to reduce the cost of production (grinding and shipping costs) and increase recovery so that the project is economically viable.
