加拿大伊康·苏利万联合公司的铜矿床于1965年6月发现。该矿床位于米斯塔西尼湖的南部,距希布加木约45公里。1966年开始采矿,矿石运往梅里耳岛采矿公司所属的选矿厂。选矿厂于1967年5月25日投产,到1970年底止,总共生产铜42,960,000磅。矿石为含于白色石英白云岩中的黄铜矿,伴生有少量贵金属。在白云岩石灰岩的顶盘与下盘两处,石英白云岩还与合碳的泥质岩相接触。矿石中没有发现其他硫化物。 1969年夏季进行了一系列预先富集试验,并于1969年末到1970年初建成了一座重介质选矿厂,该选矿厂至少在除去三分之一脉石(贫石英岩、白云岩)之后,运往希布加木选
The copper deposit of the Ikon Sullivan Union Company in Canada was discovered in June 1965. The deposit is located in the southern part of Lake Mistassini, about 45 km from the city of Sibu wood. Mining started in 1966 and the ore was shipped to the beneficiation plant belonging to the mining company Merrell. The ore dressing plant was put into operation on May 25, 1967 and by the end of 1970 a total of 42,960,000 pounds of copper was produced. The ores are chalcopyrite contained in white quartz dolomites accompanied by a small amount of precious metal. In the dolomite limestone roof and two under the plate, the quartz dolomite also with the carbon in contact with the muddy rocks. No other sulphides were found in the ore. A series of pre-enrichment tests were conducted in the summer of 1969 and a heavy-medium concentrator was completed from late 1969 to early 1970. The concentrate was shipped at least after removing one third of the gangue (lean quartzite, dolomite)希布加 木 选
