针对传统氰化提金工艺能耗高、浸出速度慢、流程较长等问题,进行了边磨边浸氰化提金新工艺的研究,塔式磨浸机是该工艺的核心设备。本文论述了塔式磨浸机的构造、工作原理、基本设计过程及主要技术特点。试验结果表明,与同规模CIP工艺的磨浸工序相比,利用该设备提金,磨矿效率可由原来的9.3kg/kW·h提高到24.5kg/kW·h,浸出时间由几十个小时降至1.5h,磨浸工序电耗为30kW·h/t矿,节电60%左右,工艺流程也大大简化。
Aiming at the problems of high energy consumption, slow leaching rate and long process of traditional cyanide gold extraction process, the new technology of gold extraction by edge milling was studied. The tower mill was the core equipment of the process. This article discusses the tower mill construction, working principle, the basic design process and the main technical features. The test results show that, compared with the same size CIP process, the grinding efficiency can be increased from 9.3kg / kW · h to 24.5kg / kW · h using the gold extraction equipment. The leaching time is from tens of hours Down to 1.5h, abrasion process power consumption 30kW · h / t mine, saving about 60%, the process is also greatly simplified.
