For Rare Gold Resource Caution Is Needed for Processing

The current mainstream gold process is usually first crushed by crusher then ground by grinding machine, and then select out the concentrate and tailings through the re-election and flotation, and finally to be refined gold smelted by chemical method.Gold resources are rare, so the dressing is not easy. At present, there are 98 kinds of gold and gold bearing minerals 98, but only 47 of which are commonly used, and among which only 10 kinds can be directly used by industry. In our country, only 38 kinds of gold-bearing material have been found so far, gold more rare. However, with the development of the dressing technique, the processing equipment has also been considerably improved.Gold ore beneficiation method has re-election method, flotation, amalgamation of the gold method. The gravity election main equipment used contain the spiral chute, shaker, jigger and short cone cyclone. Flotation - gravity election joint process (flotation tailings re-election) is suitable for adoption, and should promote that the grinding stage also carry out the sorting process, to promote this beneficiation principle that it is better if it can be as early as received .Based on the mineral structure and gold content of gold, the gold-bearing materials can be classified into three categories: gold material, gold-bearing material and gold deposit minerals. The so-called Golden independent minerals refers to the gold produced by the gold material and gold-bearing minerals, which is the nature of the most important occurrence modes of gold and also is the main object of the industrial development and utilization.disk granulator: http://www.hxjqchina.com/product-list_47.html grinding mills: http://www.crusher-machine.com/n133.htmlThe dressing process of Gold ore can be understood as:The raw ore will be screened by vibrating screen after its crushing, the product which can not through screen will be further crushed.The final products after the screening will form a closed circuit grinding...
