重选法和混汞法都是比较经济的回收黄金的方法。为了根本解决混汞法汞的污染问题,近年来,国外在应用重选工艺和设备等方面,又有一定的进展。本文主要介绍选收黄金方面成功地应用重选法代替混汞法的生产实践。一、重选法在选冶工艺中的应用(一)含金矿石应用重选法的现状国外选金厂采用重选法较为广泛,主要是用于从矿石中选别粗、细粒单体黄金、含金硫化
Re-election and amalgamation methods are more economical ways to recover gold. In order to fundamentally solve the problem of mercury contamination by the mercury-amalgamation method, in recent years, some progress has been made in application of reselection technology and equipment abroad. This paper mainly introduces the successful application of the re-election method instead of the amalgamation method in the production of gold. A re-election in the metallurgical process (a) the status quo of re-election of gold-bearing ore Foreign gold mills using re-election method is more extensive, mainly used for sorting from the ore coarse, fine-grained monomer gold , Gold vulcanization
