无污然提金新工艺是采用煤金聚团富集法及催化氯化法将金一步富集到较高品位。它尤其适用于多种类型的明金和岩金矿石;对低品位金矿和炭质金矿也有较好的应用前景,即低品位氧化型金矿回收率在80%以上,高炭质金矿回收率达82—86%。这项研究为国内首创,达到了国内领先水平。 Gold-free pollution of the new process is the use of coal enrichment and agglomeration of the catalytic chlorination of gold enrichment step to a higher grade. It is especially suitable for many types of gold and rock gold ore; for low-grade gold and carbonaceous gold ore also has a good prospect, namely, low-grade oxidized gold ore recovery rate of more than 80%, high-carbon gold Mine recovery rate of 82-86%. This research is the first in China and has reached the leading level in China.
