利用磁铁矿从氯化物溶液中回收金近年来,由于对环境保护的重视,越来越多环保和安全的浸出药剂(如氯化物和硫代硫酸盐)应用于浸出金工艺,然而从这些浸出溶液中分离和回收溶解的贵金属仍是需要面临和改进的重要技术问题。在众多方法中,吸附由于操作简单、耗能低、设备维修方便和处理能力大等优点受到重视。通常金在浸出液中尤其是废液中的含量很低,因此理想的吸附剂应具备以下特征:高效、环保、成本低、易分离和易制备。
Recovery of gold from chloride solutions using magnetite In recent years, more and more environmentally friendly and safe leaching agents (such as chlorides and thiosulfates) have been used in leaching gold processes due to their environmental protection concerns. However, from these Leaching solution separation and recovery of dissolved precious metal is still an important technical issue that needs to be addressed and improved. Among many methods, adsorption is valued due to its advantages of simple operation, low energy consumption, convenient equipment maintenance and large processing capacity. Usually, the content of gold in the leachate, especially waste liquid is very low, so the ideal adsorbent should have the following characteristics: high efficiency, environmental protection, low cost, easy separation and easy preparation.
