Atlantic Ltd. (ASX:ATI) announced the findings of a review of the mine plan, refinery and crushing, milling and beneficiation circuit for its Western Australia-based Windimurra vanadium project.

The project’s beneficiation plant was damaged in a February 2014 fire and the review “was designed to ensure that the Company has an efficient, sustainable, long-term business.”

As quoted in the press release:

The Company has now received reviews conducted by AMEC Australia Pty Ltd in respect of the CMB circuit and by Hatch Pty Ltd for the downstream refinery. These reviews have identified certain bottlenecks, along with solutions to these bottlenecks, to facilitate the plant meeting production levels that provide a long-term sustainable basis for the business going forward.
The primary production bottleneck identified in the extensive engineering study undertaken by AMEC relates to the inability of the plant to reliably produce sufficient magnetite concentrate feed to match the capacity of the downstream refinery.
After significant review and input from the Company’s technical team, AMEC’s recommended course of action involves a revision to the Windimurra process flow sheet which includes replacing the existing secondary and tertiary crushers and high pressure grinding rolls (HPGR) with a semi-autogenous grinding mill (SAG mill).
SAG mill technology is used throughout the world to process a wide variety of ore bodies and was used successfully by the previous operator of the Windimurra project.
