我国第一座工艺先进、设备装备新、自动化水平高、具有世界先进水平的炭浆提金厂,已在张家口金矿建成投产。取代了该矿原来的混汞浮选流程。新工艺流程是:细度合格的矿浆经浸前浓缩、氰化浸出、活性炭吸附、解吸电积、酸洗炭再生、冶炼和污水处理等工序,生产出纯度较高的合质金。新工艺对泥质氧化矿适应性强,金银回收率高,经济效益显著。尤其是引进的高效节能设备和仪表自动控制系统,经仿制后推广应用,对提高我国选金设备的装备水平,将会产生巨大的社会效益。
China’s first advanced technology, equipment, new equipment, high level of automation, with the world’s advanced level of carbon extract Jinchang, Zhangjiakou Gold Mine has been completed and put into production. Replaced the mine’s original amalgam flotation process. The new process is: the fineness of qualified pulp concentration before immersion, cyanide leaching, activated carbon adsorption, desorption of electricity, pickling charcoal regeneration, smelting and sewage treatment processes to produce high purity gold. The new technology has strong adaptability to the argillaceous oxide ore, high recovery of gold and silver and significant economic benefits. In particular, the introduction of high-efficiency energy-saving equipment and instrumentation automatic control system, popularized and applied after the imitation, improve the level of equipment in China’s gold election equipment, will have a huge social benefits.
