金矿CIL炭浸法工艺

【工艺介绍】:
CIL (Carbon In Leach)浸出工艺,即炭浸法提金,是一种向矿浆中加入活性炭并同时进行浸出和吸附金的工艺流程,其简化CIP(Carbon In Pulp)炭浆法工艺中氰化浸出矿浆和活性炭吸附这两步为一步,在减少损耗的同时降低管理成本。同传统的CCD工艺相比,更是节省了66%的投资成本,是现代化金矿选矿首选的工艺流程。

【应用领域】:
金矿CIL炭浸法工艺适用于品位高的大型金矿选矿和伴生银铜含量较多的金矿。相比于炭浆法和传统方法,利用此法可以得到显著的经济效益提升。对于小型金矿则推荐鑫海金精矿浮选工艺。

3.振动与脱水设备是矿浆与炭逆向运动的关键设备,利用鑫海矿装设计的液压压滤机和高效高频脱水筛,可以有效减少矿浆在连续泵送和振动筛面上的炭磨损,降低成本,便于维护操作。
