Armadale sees high-purity graphite mineralisation at Tanzania project
JOHANNESBURG (miningweekly.com) – Testwork on a 300 kg bulk sample of graphite mineralisation taken from Aim-listed Armadale Capital’s Mahenge Liandu project, in Tanzania, has produced graphite concentrates with exceptional purity of up to 99.1% total graphitic carbon, the company said on Thursday.
Excellent flake size distributions were maintained through the process with about 75% in the higher value sizes above 106 µ. The bulk sample was processed using a conventional crushing and flotation circuit, indicating that concentrates of excellent quality can be produced with relatively low processing cost.
“These results are a significant achievement as they show that extremely high-quality graphite concentrate can be produced from Mahenge Liandu using relatively simple and ultimately low-cost processing methods,” Armadale director Nick Johansen said.
He noted that this had the potential to have positive implications for the capital and operational expenditure requirements of the project.
“We now look forward to further proving up the project’s resource potential through our two-phase drill programme, which is well advanced, with results due from the first stage in the coming weeks.”
