Resumen de TIVAN extraction process underpins TNG project
"TIVAN is an acid leach process that produces high purity vanadium [pentoxide] at 99%, iron [oxide] at purities of 99.9% and purities of 50-55% titanium dioxide," Paul Burton, TNG's MD, explained to IM.
The company began exploring the process in 2009, and over that time it has progressively increased the specifications of the process. In 2010 TNG applied for a patent for TIVAN, and later pilot-plant test work was completed during 2012 as part of the Mount Peake pre-feasibility study, which successfully produced high-purity aqueous solutions which primarily lead to the production of high-purity TiO 2, V 2 O 5 and Fe 2 O 3.
"The TIVAN process is critical to the economics of the Mount Peake project and underpins our pre-feasibility study," Burton said. "The separation of the three key commodities we have achieved through the TIVAN process provides us with significant life of mine revenues over $10bn."
