Our mineral molybdenum over half a century, molybdenum processing plant development from the old China only Yangjiazhangzi molybdenum processing plant now has more than 50 plant molybdenum, copper and molybdenum plant, tungsten, molybdenum, bismuth and molybdenum processing plant selected factory production of molybdenum concentrate. Molybdenum beneficiation technology gap with advanced countries has become increasingly smaller. 

 

Our main beneficiation methods molybdenum flotation. When deep-election to contain trace amounts of molybdenum ore copper-based, using a part of the mixed - flotation process flow. Valuable mineral ore Jinduicheng molybdenum processing plant is molybdenite, pyrite and minor chalcopyrite, using a molybdenum-copper flotation tailings flotation of pyrite, copper - molybdenum and molybdenum separation part of the mixed concentrate - flotation process. Now, China is still recovering from a copper-molybdenum ore beneficiation of molybdenum, copper and molybdenum is commonly bulk flotation process, and thus copper-molybdenum separation and selection of molybdenum concentrate. 

 

Copper-molybdenum separation and selection of molybdenum concentrate mainly used sodium sulfide and sodium cyanide Law Act. Choose depends primarily on the number of molybdenum molybdenum total enrichment ratio. General is the total concentration ratio, the selected number is usually more; overall enrichment ratio is low, the selection of the number of usually less. If higher Molybdenum plant processed ore grade ore (0.2% to 0.3%), enrichment ratio is 133 to 155 times its original design featured a total of seven times, and a plant Jinduicheng processed raw ore grade of about 0.1% molybdenum enrichment ratio of 430 to 520, the total number of selected 12 times. In recent years, in order to meet the needs of molybdenum concentrate exports, Jinduicheng molybdenum processing plant using hydrochloric acid - ferric chloride leaching method except molybdenum concentrate impurities. 

 

Some of the colored system from molybdenum processing plant, the ore grade processed varied widely, high above 0.3% lower at 0.1%, some only 0.02%. The vast majority of the actual mineral recoveries above 80%. The resulting concentrate grade of 45% to 54% more than in the tailings grade of 0.02%, higher at 0.04 percent, lower at 0.01%.
