Non-ferrous metal ores often associated small amount of gold. These golds are usually contained in polymetallic ore and copper ore mainly composed of copper , lead and zinc . The grade of gold is not high, generally not more than 2 grams / ton. However, due to the large scale of non-ferrous metal deposits, the production of associated gold accounts for a large proportion of the total gold production. In the recovery of this part of the gold, we should first consider the non-ferrous metal minerals as a qualified product, and then provide the necessary conditions for the recovery of gold or special gold selection operations (such as amalgamation , cyanide), in order to enrich the gold as much as possible. In the non-ferrous metal concentrate products or enriched in special gold selection operations. To deal with this type of ore, it is important to grasp the symbiotic relationship between the occurrence of gold in the ore, gold and other minerals, and use this as a basis to determine a reasonable process. For gold enriched in various concentrates, it is generally recovered in the smelting. This type of ore sorting method has been discussed in detail in non-ferrous metal beneficiation . 60 Television,60 Inch Hotel Smart Tv,Digital Television,60 Inch Smart Television Jiangsu Hengye Precision Technology Co.,Ltd , https://www.hdigitaltv.com
