Windimurra Vanadium Beneficiation Plant

Windimurra Vanadium is located near Mount Magnet in Western Australia. The vanadium processing plant is operated by Midwest Vanadium (MVPL) which is 100% owned by Atlantic Limited.

Plant Upgrade 2012

The plant consists of a crushing, high pressure grinding, beneficiation, roasting and refinery stages. The front end of the plant was suffering from a large amount of fines in the circuit. MVPL planned to add additional screening capacity to the existing crushing circuit, Primero took the concept and turned it into an operating screening plant.

The turnkey project involved the design, construction and commissioning of multiple pieces of machinery including magnetic separators, conveyors, double deck screens, vibrating feeders and pumps. Primero completed civil, structural, mechanical, piping and electrical design works as well as procurement, fabrication and site installation. The project works commenced in February 2012 with successful commissioning of the works completed in July 2012.

Plant Rebuild 2014/15

Due to a catastrophic fire at their Windimurra Mine, Midwest Vanadium required the replacement of the beneficiation plant. The scope of the project was a turnkey plant complete with process optimisation, civil, structural, mechanical, piping, electrical, instrumentation and control design.

The project included full replacement of the beneficiation plant including new magnetic separators (44 drums), new slurry distribution system complete with hoppers, pumps, piping and underflow collection launders.

A 10 tonne semi portal crane was installed as part of the project for maintenance of the magnetic separators and slurry distributors.

Plant services included process water, raw water, fire water, gland seal water and instrument and plant air distribution networks. The electrical distribution system was retrofitted into existing MCC’s not damaged by the fire. The existing plant PLC was replaced with a DCS as part of the project.

The project has been fast tracked due to the critical production nature of the building.

The full design was to be completed in 12 weeks with site works commencing only 3 weeks after project kick-off. The building design includes modularised skid which will be pre-fitted on the ground and lifting into position.
