Youanmi Vanadium Project Metallurgical Test Results Confirms Significant High Grade Beneficiation of Oxide Samples Perth, Oct 16, 2018 AEST (ABN Newswire) – The Directors of Venus Metals Corporation Limited.
HIGHLIGHTS:
– The grade increased from 0.58% V2O5 to 0.80% V2O5 with a recovery close to 80% of the Vanadium.
– At -1 mm more than 40% of the mass can be rejected whilst recovering 80% of the Vanadium.
– Mass rejection of gangue minerals decreases downstream processing volume and is expected to reduce acid consumption.
– Assay by size data suggests the oxide sample can be significantly beneficiated without the need to grind the sample.
– Crush sizes tested showed minimal variation in the beneficiation potential.
– Further testwork is planned for hydrometallurgical studies on a beneficiated sample.
Metallurgical Testwork
The Company commissioned METS Engineering Group (“METS”) to develop a series of metallurgical tests aimed at beneficiating an oxide composite formed using different intervals from the deposit (see Table-1 in link below) (see Figure 1 in link below). The oxide composite was formed from shallow intervals spanning five diamond core holes seen in the table below (see link below). Only half of the mass for each interval was utilised, with the remaining kept in reserve. A total composite mass of approximately 48 kg was formed. The representative composite encompassed various weathered zones and a range of different spatial locations throughout the deposit.
Beneficiation testwork focused on low cost methods that avoided grinding. The testwork was conducted at three crush sizes: -3.35 mm, -2 mm and -1 mm (refer Appendix-1 JORC Table) (see link below). Due to the friable nature of the oxide ore these crush sizes are expected to be achievable using a combination of comminution technologies.
