Australian Vanadium tests boost Gabanintha recovery rates

Date: Jan 10, 2018
Australian Vanadium Ltd’s (ASX:AVL) initial leach test results support the high quality nature of material from Gabanintha Vanadium Project in Western Australia.

Neomet hydrometallurgical process tests returned encouraging first pass results for extraction of vanadium, iron and titanium from oxide samples.

A high-grade oxide sample showed extraction of 96% of vanadium, 87% of iron and 1% of titanium after a one hour hydrochloric acid (HCl) leach.

The titanium was upgraded from 8.8% to 23.4% in the residue.

A low-grade sample showed extraction of 88% of vanadium, 97% of iron and 33% of titanium after a one hour HCl leach.

Evaluating processing routes

Australian Vanadium has engaged with Neomet and Sedgman to conduct the tests as it evaluates traditional and non-traditional processing routes.

Vincent Algar, managing director, said: “As AVL moves towards defining the exact nature of the Gabanintha operation through its definitive test work, processing circuit design and mine design, we will continue to have all options on the table.

“The exciting results from the initial Neomet leach test work allow us to better understand the potential recovery of other valuable metal credits.”
