This thesis studied the roasting molybdenum concentrate ash rhenium recovery method, the analysis of the main ingredient in roasting dust, on the basis of determining the smoke of rhenium with new leaching agent in the process. Experimental study on the leaching process of the main influence factors such as: leaching temperature, leaching time, liquid-solid ratio and so on, to explore the optimal leaching condition. Through leaching system research, combining with the characteristics of leachate, select ion exchange resin adsorption separation, leaching liquid of rhenium in the process. Through experiments, the choice is suitable for the separation and enrichment of rhenium 717 strong base anion ion exchange resin. Experiment studied 717 resin main influence factors in the adsorption process, such as: solution pH, the saturated adsorption capacity, rhenium, molybdenum separation factor, etc.; To explore the desorption condition of rhenium resin. Based on comprehensive study of the proposed leaching rhenium, rhenium 717 resin enrichment separation process. Using this process, the leaching rate of rhenium in the smoke in 95% above, in the solution of rhenium absorption rate above 99%. Accompanying rhenium resin rhenium analytical rate above 99%. This process is effective recovery of rhenium in the dust, improve the resource utilization rate and economic benefit. Of smoke is also leaching process, the principle of ion exchange resin is discussed.
