VNIPIpromtechnologii Developed Method for Associated Rhenium Production at Balkhash Copper Smelter (Kazakhstan)
The project was implemented by order of the largest copper producer in Kazakhstan, KazakhMys Development, LLP. «We were tasked with developing a method for sorption extraction of rhenium from the washing acid used by the sulfuric acid shop. We proposed a genuine process flow and options for placing equipment for a dedicated production area. The method itself is based on the processes of sorption, regeneration and treatment of rich eluate. Lead concentrate may become a by-product of the proposed production area. When developing the project, we paid special attention to the compliance with environmental standards. In particular, a method for treating emissions into the atmosphere that completely eliminates air pollution is proposed», said Alexey Shemetov, Director General of VNIPIpromtechnologii, JSC.
The method will also allow optimizing the existing production process and reduce the expenses, including the ones for the chemicals and consumables.
Note that the demand for rhenium, primarily for production of jet engine exhaust nozzles and combustion chambers, is constantly growing. The production of this rare metal in the world increased from 40 to 57 t/year just for the period from 2006 to 2015.
