内蒙古某金矿选冶工艺设计

内蒙古某金矿原矿品位1.64g/t,金是唯一有价金属元素,具有整体储量较大、矿石品位高低不同和矿石类型不同等特点。通过对原矿矿石性质、选矿试验进行分析,发现选冶指标存在差异。为了保证矿山经济效益发挥到最大,确定了对较高品位矿石采用全泥氰化工艺方案,对较低品位矿石采用堆浸的工艺方案。对破碎系统、全泥氰化系统和堆浸系统的工艺流程分别进行了论述,同时在保证设计指标和工艺参数的前提下,合理的选择了高效节能的选冶设备,并结合现场地形进行了设备优化配置。

Beneficiation and Metallurgical Process Engineering of Certain Gold Mine in Inner Mongolia

ROM grade of certain Inner Mongolia Gold Mine is 1.64g/t, and gold is the only valuable metal. The Mine is featured with big reserve, diversified grades and different types of ores. Through analysis on ore properties and mineral processing test results, it was found that the processing and metallurgical indices vary in a great extent. To ensure maximum economic benefit of the Mine, a process to treat high-grade ores with all-slime cyanidation technique and treat low-grade ores with heap leaching technique was adopted. The thesis provided a general illustration on crushing system, all-slime cyanidation system and heap leaching system of the Mine, in addition, under the prerequisite to guarantee design indices and process parameters, the thesis also discussed selection of high-efficient and energy-conserving processing and metallurgical equipment as well as equipment configuration optimization as per site relief.
