Worldwide, mercury used and lost by artisanal and small-scale gold miners (ASGM) represents today 30% (or 1000 tonnes/a) of the all industrial uses of mercury. Most mercury mines are being closed and mercury trading will be banned in Europe in 2011 and US in 2013. This will create difficult moments for the small miners who rely on mercury to recover quickly the easily extractable gold. ASGM all over the world will need to look for alternative processes if they want to keep their sources of income.

在世界范围内，手工和小规模采金者（ASGM）使用和损失的汞占所有汞工业用途的30%（或1000吨/年）。大多数汞矿正在关闭，欧洲将于2011年禁止汞交易，美国将于2013年禁止汞交易。这将给依赖汞快速回收容易提取的黄金的小矿工带来困难。世界各地的手工和小规模采金业如果想保持收入来源，就需要寻找替代工艺。
