由紫金山金矿副矿长、高级工程师杨云中设计研制的“敞中式非流态化固定床吸附装置”,被家知识产权局授予实用新型专利权。 该实用新型装置采用多级串联吸附,其吸附率可达98％以上,而且在吸附过程中无动力消耗,节电效果显著,可以替代现有的塔（柱）式吸附、搅拌吸附,具有处理量大、吸附率高、操作方便等优点。这种装置可广泛应用于黄金行业堆浸法提金工艺、全泥氰化逆流洗涤活性炭吸附工艺。该装置填补了国内空白,具有极高的推广价值。 紫金山金矿是以堆浸法提金为主的大型黄金生产矿山,浸出富液中金的分离采用活性炭吸附工艺,随着矿山生产规模的扩大,最早采用的塔式吸附已
By the Zijinshan Gold Mine, deputy director, senior engineer Yang Yun in the design and development of “open medium non-fluidized fixed bed adsorption device” by the intellectual property office granted the utility model patents. The utility model adopts multistage tandem adsorption, the adsorption rate can reach more than 98%, and has no power consumption in the adsorption process, and has the advantages of energy saving effect, which can replace the existing column adsorption, agitation adsorption and treatment Large amount, high adsorption rate, easy operation and so on. This device can be widely used in the gold industry heap leaching gold extraction process, full mud cyanide countercurrent washing activated carbon adsorption process. The device to fill the gaps in the country, with a high promotional value. Zijinshan Gold Mine is based on heap leaching of gold-based gold production of large gold, gold-rich leaching solution using activated carbon adsorption process, with the expansion of mine production scale, the first tower adsorption has been
