广东信宜金矿
该矿系低品位硫化物型金矿。原矿试样金品位1.1g/t，主要是以中细粒的自然金存在，是我公司即将开发的金矿之一。我院为其制定了尼尔森机重选－炭浸法工艺，选冶试验金的总回收率达到91.9%，其中尼尔森机重选回收率34.85%，精矿品位617.2g/t。该工艺已被广东宝源公司和南昌有色冶金设计院用于该矿选矿厂设计。

The sample size of the gold ore is 1.1g/t, mainly in the presence of medium and fine grained natural gold. In our institute, the author developed a new method of gravity separation and carbon leaching for the machine. The total recovery rate was 91.9%, of which the recovery rate was about 34.85% and the concentrate grade was 617.2g/t. This process has been the source of treasure of Guangdong company and Nanchang Nonferrous Metallurgy Design Institute for the ore dressing plant design.
