Pollution control and exploration of sustainable development for the Bingham mine with a century's history in Western United States

摘要:
美国宾汉姆斑岩铜矿是全球著名矿床,近百年的资源开发、矿石加工和冶炼等生产活动对当地环境和生态系统造成了严重破坏,污染治理成本高昂。此外,矿区还有大量其他矿业公司历史上遗留下的污染物,治污责任纠缠不清。然而依照国家法律、政府,以及企业的社会责任心与发展策略,该区环境污染得到了成功清理和复垦,企业重新走上一条可持续发展之路,产生了显著的环境、社会、监管和经济效益。介绍宾汉姆矿山治理迂回曲折的过程,试图能给中国现有同类矿山、国家相关管理部门带来有益启迪和借鉴。
Abstract:The Bingham porphyry copper deposit is a world-famous ore deposit. More than one hundred years' production activities such as resource development, ore processing and smelting have seriously damaged the local environment and ecosystem, and the cost of pollution control is high. In addition, there are a large number of other pollutants left behind in the history of the mineral company in the mining area, and the responsibility for pollution control is entangled. However, according to the national law, government and corporate social responsibility and development strategy, the environmental pollution has been successfully cleaned up and reclaimed, and enterprises have embarked on a sustainable development road, resulting in significant environmental, social, regulatory and economic benefits. This paper introduces the process of the Bingham mine's pollution abatement characterized by many twists and turns, with the purpose of giving some beneficial enlightenment and reference to China's existing similar mines and related administrative departments.
