法国萨尔西金矿山(Salsigne)正在试验一种从尾矿中回收金的新方法.这种方法称为德瓦奥尔班法(De Vol-Holbein Process)在三个月的试验期间.计划每天处理约3吨含金尾矿.如果试验效果良好,将新建一座日处理3000吨含金尾矿的工厂.新提金法是用各种具有高孔隙度的固态化合物(如玻璃、聚氨基甲酸酯、聚苯乙烯等)从溶液中回收金.这些化合物能很好地吸附溶液中的金属,且具有很高的选择性.这种新方法适合于处理某些难选矿石,例如含高砷的矿石.这种矿石用常规氰化法处理时,其工艺是非常复杂的.
Salsigne, France, is experimenting with a new method of recovering gold from tailings, known as De Vol-Holbein Process, during its three-month trial. Processing about 3 tons of gold-bearing tailings.If the test results are good, a new factory will be built to process 3,000 tons of gold tailings per day.The new gold method is to use a variety of high-porosity solid compounds (such as glass, Acid esters, polystyrenes, etc.) These compounds recover the metals in solution well and have high selectivity.The new method is suitable for the treatment of certain refractory ores, for example containing high Arsenic ore. The ore is treated with conventional cyanide process, the process is very complicated.
