本技术涉及一种选矿工艺,实际上是一种在含金的氰渣中提取金精矿的选矿工艺。目前,我国黄金冶炼一般采用氰化法进行,虽然回收率很高,但是冶炼后的氰渣中每吨还有1.5~2g 黄金被排走,现在,冶炼厂家直接把氰碴排放掉,不进行回收,造成了很大的浪费,是很不经济的。本技术就是要提供一种能够使含金氰渣中每吨所含1.5~2g 的黄金被回收,成本低,回收率高的提取金精矿的生产工艺。从含金的氰渣中提取金精矿的生产工艺,是由脱泥、摇床等工序组成,其特征在于含金的氰渣进入到脱泥装置后进行脱泥,比重小的氰渣进入尾矿管排走,比重大的含金氰渣进入到 n 级摇床(n≥1的自然数),通过摇床使比重小的氰渣进入尾矿管排走,比重大的为金精
The present technology relates to a beneficiation process, in fact, a beneficiation process for extracting gold concentrates from gold-bearing cyanide residues. At present, China’s gold smelting generally used cyanide method, although the recovery rate is high, but after smelting cyanide residue per ton there are 1.5 ~ 2g gold was discharged, and now, the smelter directly to the cyanide emissions, do not proceed Recycling, resulting in a great waste, it is not economical. The technology is to provide a production process capable of recovering gold of 1.5-2g contained in gold cyanide residue per ton, with low cost and high recovery rate. The process of extracting gold concentrate from the gold-bearing cyanide residue is made up of steps such as desliming and shaker. The method is characterized in that cyanide residue containing gold goes into the desliming device for desliming, Tailings pipe row away, the larger gold cyanide residue into the n-stage shaker (n ≥ 1 natural number), through the shaker so that a small proportion of cyanide residue into the tailings pipe discharge, the major proportion of gold
