项目摘要
Amalgamation from artisanal gold mining represents today the main source of mercury pollution in the planet releasing/emitting between 1400 and 1600 tonnes/a of metallic mercury. Approximately 16 million individuals, spread over virtually all developing countries, are directly involved in extracting gold using rudimentary techniques. Artisanal miners are currently extracting 300 to 500 tonnes/a of gold worldwide increasing river siltation, mercury pollution, and generating many other environmental, political and social problems. This Discovery Grant proposal is in line with my former grants that has focused on reduction/elimination of mercury pollution from artisanal gold miners worldwide. This proposal has as its main objectives the following steps:
1) Investigation of mercury-free technologies to extract gold using intensive cyanidation or other lixiviants from gravity/flotation concentrates in small ball mills or filtration systems (to speed up the leaching process)
2) Feasibility study of the alternative methods to be implemented in small scale
3) Demonstrate and replicate the “new” techniques in the Training Centres being installed by UBC in developing countries in partnership with Governments.
The ultimate objective of my work is to transform artisanal-disorganized-illegal miners into small-formal-responsible miners. This proposal is just a piece of this intricate puzzle that involves trust, education, organization, capital and then legalization of the miners. The main stakeholders repository of the findings of the work described in this proposal are the top artisanal miners, owners of processing centres, who have basic knowledge and capital to make changes in the sector.The techniques to extract gold to be demonstrated to artisanal miners must be simple, efficient fast and affordable. The majority (>70%) of the mercury releases/emissions from artisanal gold miners occur when they amalgamate the whole ore. The current proposal intends to promote simple gravity concentration + column flotation techniques followed by leaching of concentrates using ball mills or filtration systems. The proposal has a strong component of field work for training miners, academics and authorities to demonstrate success cleaner methods to leach gold. This will occur using the Training Centres for Artisanal Miners that are being implementing by UBC MINE. The novelty of this proposal is the development of new small-scale gold extraction methods and adaptation of existing industrial techniques for the reality of the artisanal miners.
手工采金业的汞合金化是当今全球汞污染的主要来源,每年释放/排放1,400至1,600吨金属汞。大约有1 600万人,几乎分布在所有发展中国家,直接参与使用初级技术开采黄金。目前,全世界手工采矿者每年开采300至500吨黄金,增加了河流淤积、汞污染,并产生了许多其他环境、政治和社会问题。这项发现补助金提案与我以前的赠款一致,以前的补助金侧重于减少/消除世界各地手工金矿工人的汞污染。这项建议的主要目标是:
1)研究无汞技术,在小型球磨机米尔斯或过滤系统中,使用强化氰化法或其他浸滤剂从重力/浮选精矿中提取黄金(以加快浸滤过程)
2)小规模实施替代方法的可行性研究
3)在不列颠哥伦比亚大学与各国政府合作在发展中国家建立的培训中心展示和推广“新”技术。
我工作的最终目标是将无组织的非法手工采矿者转变为负责任的正规小采矿者。这个提议只是这个错综复杂的难题的一部分,涉及到信任、教育、组织、资本,然后是矿工的合法化。本提案所述工作结果的主要利益攸关方是顶级手工采矿者和加工中心的所有者,他们拥有基本知识和资本,可以在该部门进行变革,向手工采矿者展示的黄金开采技术必须简单、高效、快速和负担得起。手工金矿工人的汞释放/排放大多数(>70%)发生在他们对整个矿石进行混汞处理时。目前的提案打算推广简单的重力选矿+柱浮选技术,然后使用球磨机米尔斯或过滤系统对精矿进行浸提。该提案有一个强有力的组成部分,即培训矿工、学者和当局的实地工作,以展示成功的更清洁的浸金方法。这将通过UBC矿业正在实施的手工采矿者培训中心来实现。这一提议的新奇在于开发了新的小规模黄金开采方法,并根据手工采矿者的实际情况调整了现有的工业技术。
