自然界最简单银矿物是自然银和银的简单硫化物—辉银矿—螺状硫银矿。回收自然银和辉银矿—螺状硫银矿中的银方法很多。重选、混汞、浮选、氰化、硫脲或其中几部分的联合流程。但该矿物中自然银占银矿物量的20.68％,自然银的比重较大可浮性较差用单一浮选指标不理想。目前世界上仍有不少用传统的氰化法来回收银,指标是很高的。而氰化尾水处理已不成问题。由于该矿石矿物组成简单。金属矿物只占矿物总量的1.16％。脉石矿物占98.94％。而自然银和辉银矿—螺状硫银矿之和就占银矿物总量的99％以上。该矿石的氧化程度较高,用氰化法提银是较
The simplest silver minerals in nature are natural sulfides of silver and silver - aurora-spiro silver sulfide. Recycling natural silver and glitter silver - There are many ways to silver in a silver-sulfur mine. Re-election, amalgamation, flotation, cyanidation, thiourea or a combination of several processes. However, the natural silver in the mineral accounts for 20.68% of the amount of silver minerals. The larger the proportion of natural silver, the worse the floatability is, and the single flotation index is not ideal. There are still many in the world using traditional cyanide method to recover silver, the index is very high. The cyanide tail water treatment is not a problem. Due to the ore mineral composition is simple. Metallic minerals account for only 1.16% of the total mineral. Gangue minerals accounted for 98.94%. The sum of natural silver and glitter silver - sulfur sulfur silver ore accounted for more than 99% of the total. The higher degree of oxidation of the ore, silver cyanidation is more
