黄金选冶技术有重大突破微细粒金选冶技术是当今世界选冶技术难题之一。我国已探明有微细粒金储量５００ｔ，因选冶困难不能开采，成为呆矿。中国科学院科技工作者研制出的选冶工艺流程，使我国的微细粒金开采成为可能，可带来几百亿元的效益。他们还研制并推广应用了铅基...
Gold smelting and metallurgical technology has a major breakthrough Micronuclear Metallurgical Smelting and metallurgy technology is the world today, one of the challenges of technology. China has proved that there are 500t reserves of fine grain gold, because of the difficulty of mining and dressing can not be mined, become a dug mine. Chinese Academy of Science and Technology workers developed the process of metallurgical and metallurgical, micro-gold mining in our country made possible, can bring hundreds of billions of benefits. They also developed and promoted the use of lead ...
