The application prospect of Nielsen concentrator in China

Many of gold gold ore minerals are disseminated to uneven thickness distribution, now using the re-election - flotation or reselection - CIP recovery process, using methods reselection amalgamation, chute, jig and the like. Mercury amalgamation poses a great threat to the health of the factory environment and the workers; the gold recovery rate of the chute and the jigging is very low (generally no more than 10%), and the jig has a problem in the process, which gives The re-election method casts a shadow on the use of the gold mining plant. In addition, since the coarse to medium grain gold is not well recovered in the re-election section, the subsequent flotation has a poor effect on their recovery, or the current leaching time is not enough to completely dissolve them, resulting in a part of the gold loss. In tailings, the recovery of gold is reduced. If the Nielsen concentrator is used for re-election, the coarse-to-medium gold can be recovered more completely, and the above problems will naturally not occur again. Therefore, it is a good choice to replace the mercury, chute, and jigging equipment in the grinding process of the gold processing plant with the Nielsen machine. China's Shandong Yingezhuang gold mine, Henan Jinqu gold mine, Shanxi Fanyu gold mine are all successful production examples. The test results of three gold mines of our company also confirmed this conclusion.

China has a lot of gold thicker non-ferrous metal mines (such as Hubei cages GOLD copper mine, Sanxin bronze shares of the company and Henan Jinyuan gold mining companies, etc.), the current gold by flotation selected into the copper concentrate, Sold to the smelter. First, there is a problem of low gold recovery rate; second, the price of gold is lower than commodity gold; third, the net return value given by the gold smelter is low, affecting the economic benefits of mining enterprises. As early as a few years ago, the Jilongshan gold-copper mine had the idea of ​​producing some gold, but it did not find a good strategy. Now I suggest that the mine use the Nielsen concentrator to achieve this goal.

Jinchuan copper-nickel ore and so contains higher grade copper DEXING coarser and PGE, Nelson machine includes potential applications of recovering platinum group elements. Jinchuan Company is conducting the test, and according to the application situation in Russia, it is possible to achieve good results.

There are still many gold deposits in the remote areas such as the Qinghai-Tibet Plateau to be developed, but no simple and easy method has been found yet. Nielsen machine has a large processing capacity, high enrichment ratio, light weight, low power consumption, and low water consumption. It will be fully utilized in the plateau and remote areas, and it is a good way to recover gold from remote mountainous areas.

In addition, there are rich resources of tungsten ore, tin, mercury, silver ore, may replace the existing test flow jig and a portion of the shaker with Nelson machine, to simplify the process and reduce the plant area, to improve the metal recovery .

In summary, there are many potential gold-bearing gold deposits, associated gold or platinum non-ferrous metal mines, gold deposits in remote mountainous areas, coarse-grained tungsten-tin ore, mercury ore, silver ore, etc. The Nielsen machine simplifies the process and increases the likelihood of recovery. Therefore, the Nielsen concentrator has broad application prospects in China.
