Abstract

Central Sulawesi has a large amount of gold deposits unevenly extended in a number of regencies and cities. Some companies with concession land have already held contract of work and mining concession but yet to exploit the land. Most mining activities existed are traditionally conducted in the concession land. The inability of the local government to control the activities has led encroachment to protected forest and agricultural land. The consumption of mercury in gold processing could reach 34,000kg mercury day-1 with gold production approximately 22.5-45 kg day-1. The improper use of mercury has caused chemical, biological and physical soil degradation.

印度尼西亚苏拉威西岛中部金矿开采活动及其对土地退化的影响
苏拉威西中部有大量的金矿,分布在一些县和城市。一些拥有特许土地的公司已经签订了工作合同和采矿特许权,但尚未开发土地。现有的大多数采矿活动传统上都是在特许土地上进行的。当地政府无力控制这些活动,导致受保护的森林和农业用地受到侵犯。黄金加工过程中的汞消耗量可达3.4万公斤汞,黄金产量约为22.5-45公斤。汞的不当使用造成了土壤的化学、生物和物理退化。
