一、常规金泥冶炼工艺概述 江西省修水县土龙山金矿是个具有25t/d采选能力的地方国营矿山。选厂1991年9月投产,采用重选-重尾氰化-锌丝置换工艺流程,除重选毛金外,中间产品还有金泥.所谓金泥,通常指氰化法提金过程中,用锌(锌粉或锌丝)从含金的贵液中置换得到的一种富金泥,近乎黑色的泥状沉淀. 以前,现场氰化泥按常规方法,经预处理、冶炼两个阶段,其原则流程如图1所示:
First, the conventional gold mud smelting process overview Xiujiang County, Jiangxi Province is a local gold mine with 25t / d mining capacity of local state-owned mines. Selective plant put into operation in September 1991, the use of re-election - heavy tail cyanide - zinc wire replacement process, in addition to re-election gold, the intermediate products also gold mud. The so-called gold mud, usually refers to the gold cyanide process, with Zinc (zinc or zinc wire) is a kind of gold-rich mud, almost black mud-like sediment displaced from the gold-containing precious liquid. Previously, on-site cyanide mud was pre-treated and smelted according to a conventional method The principle of the process shown in Figure 1:
