红狗是世界第二大锌矿床,仅次于澳大利亚的布罗肯希尔锌矿床。全面投产后,它将成为世界最大的贱金属矿,锌精矿的额定产量为50.8万吨/年。它位于北极圈以北160公里,是世界环境条件最恶劣地区之一。现有可供50年开采的矿石储量估计为7700万吨,平均品位:锌17.1％,铅5％,银82克/吨。精矿外运受季节影响,仅能在夏季不封冻的90～100天内进行。约50％的 Red dog is the world’s second largest zinc deposit, second only to Australia’s Broken Hill zinc deposit. When fully operational, it will become the largest base metal mine in the world with a zinc concentrate output of 508,000 tonnes / year. Located 160 kilometers north of the Arctic Circle, it is one of the worst environmental conditions in the world. The existing ore reserves available for 50 years of mining are estimated at 77 million tonnes with an average grade of 17.1% for zinc, 5% for lead and 82 g / t for silver. Concentrate outsourcing affected by the season, only in the summer does not freeze 90 to 100 days. About 50%
