根据富家坞、多宝山等斑岩铜矿床的地质特征及有关资料,我们在π型高压釜中应用气相搬运法,实验研究了铜在碱金属氯化物介质溶液中的迁移能力,现介绍如下.实验方法(一)高温高压实验方法1.实验设备:除常规设备外,本实验使用的高压釜为纯钛(TA_2)及钛基合金(TC_9、665)π型高达釜.这种高压釜,在加工工艺良好的情况下,铜的回收量在85%以上,大多数高于90%.经过处理后可大大提高抗腐蚀性能.在温度≤500℃、压力≤500atm条件下可长期使用.2.实验条件的选择:我国大多数斑岩铜矿床均与浅成中酸性斑岩体有关.矿体常富
According to the geological characteristics and related data of porphyry copper deposits in Fujiwu and Duobaoshan, we used gas phase transport method in π-type autoclave to experimentally study the migration ability of copper in alkali metal chloride solution as follows Experimental methods (a) high temperature and high pressure experimental methods 1. Experimental equipment: In addition to conventional equipment, the experiment used for the autoclave titanium (TA_2) and titanium-based alloy (TC_9,665) π type up to the autoclave , In the case of good processing technology, the recovery of copper in more than 85%, most of more than 90%. After treatment can greatly improve the corrosion resistance of the temperature ≤ 500 ℃, pressure ≤ 500atm conditions for long-term use. 2. Choice of experimental conditions: Most of the porphyry copper deposits in China are related to the epithermal acid porphyry bodies.
