Tando Resources can produce vanadium concentrate grading well over 2% vanadium pentoxide using simple magnetic separation on high-grade SPD ore.
A series of outstanding assays from phase one drilling at the SPD vanadium project in South Africa has put Tando Resources (ASX: TNO) on track to realise its strategy of near-term cash flow from early production.
The latest round of concentrate samples from SPD have generated high-grade vanadium and continue to support the junior’s strategy of fast-tracking the operation by processing the near-to-surface, high-grade zones via simple magnetic separation.
The assays show that this method can produce concentrate grading well over 2% vanadium pentoxide from high-grade samples.
Best magnetic concentrate results were 25 metres at 2.42% vanadium pentoxide from 23m, including 8m at 2.32% vanadium pentoxide (for mass recovery of 41%); 34m at 2.32% vanadium pentoxide from 21m; and 35m at 2.15% vanadium pentoxide from 21m (mass recovery 45%).
Low capital costs
Mass recovery refers to the weight of magnetic material recovered as a percentage of the total sample weight.
It can contribute to low capital costs and a shorter lead time to production.
The higher the mass recovery, the less material is required to be processed to achieve a production target and the less waste needs to be disposed of or stored.
Recovery from SPD is believed to be positive across all mineralised intervals, increasing to well above 40% in the zones grading more than 1% vanadium.
The concentrate samples, which contains low levels of silica and alumina, have been provided to potential offtake partners for review.
