1、内蒙古科技大学 毕业设计 I 摘要摘要 河北八道河金矿选矿厂年处理能力为 30 万吨/年，处理原矿粒度 500-0MM。 八道河金矿原矿品位是 6g/t。采用阶段磨矿，阶段选别工艺。主要的选别工 艺有重力选矿，氰化浸出工艺，锌粉置换。 主要工艺介绍如下： 破碎工艺选用三段一闭路破碎，在细碎前有一预先和检 查筛分合一的筛分过程。磨矿为阶段磨矿，两段全闭路磨矿。在一段磨矿后首先用跳 汰机进行一次重选，选出粗粒的单质金。在两段磨矿后，进行一次浓缩处理。产品经 过浸出槽进行 13 段氰化浸出。后经两道洗涤处理，矿浆先后通过贵液缓冲池和贵液 池，通过管式过滤机进行净化处理。再通过脱氧塔进行脱氧处理，最后
2、到达板框压滤 机，在压滤机中加入锌粉，与金进行置换反应，得到最终产物金泥。 关键字：重选，氰化浸出，置换 内蒙古科技大学 毕业设计 II Abstract Hebei badaohe gold mine an annual capacity of 300,000 tons / year, processing ore particle size 500-0MM.

3、paration, cyanide leaching, zinc dust. The main technical description is as follows: crushing process used a closed-circuit breaking three sections, in a pre-crushing and inspection before the screening process of screening unity. Grinding for the stage grinding, two full closed-circuit grinding. Af
4、ter grinding in a jig for the first time with the re-election to elect a single quality of coarse gold. After grinding in two, for a concentrated treatment. Product after leaching for 13 slots cyanide leaching. After two washing after handling, pulp has your solution through the buffer pool and your liquid pool, through the tubular filter for purification. Oxygen through the oxygen tower and then, at last reach the frame filter, the filter by adding zinc, and gold for the replacement reacti
