BRAZIL – Largo Resources of Toronto has announced plans to boost vanadium pentoxide production by 25% at its Maracas Menchen mine in Bahia state, about 813 km northeast of Brasilia. Monthly production would increase to 1,000 tonnes, and it may be possible to boost it further to 1,100 tonnes with operational improvements to the roasting kiln.

The increase would take effect after June 2019 following 12 months of construction and an anticipated US$15.5 million in capital expenses. The plan focuses on boosting capacity in the mill, fusion (de-ammoniator, furnace and flaking wheel), leaching, and filtering areas.

Largo produced 903 tonnes of vanadium pentoxide in December 2017. Please visit
