Sarytogan Graphite Ltd (ASX:SGA) MD Sean Gregory tells Proactive the company has achieved saleable graphite concentrate grade of 81.4% total graphitic carbon (TGC) at 84.4% metal recovery from the latest bulk flotation testing of samples from its Sarytogan Graphite Deposit in central Kazakhstan. The 60 kilograms of composite samples blended from eight diamond drill holes from the northern and central graphite zones at an average head grade of 32.5% TGC were tested in September at the Perth lab of Metallurgy Pty Ltd. Significantly, the metal yield is higher than the 76.6% previously achieved on the same sample at the bench scale, which means that the project has the potential to deliver very low operating costs per tonne of flotation concentrate.
The results of the bulk concentrate test confirm that saleable graphite concentrate (greater than 80% TGC) can be readily produced from the giant and exceptionally high-grade Sarytogan Graphite Deposit, Gregory said.
Allocations of bulk concentrate have now been received by multiple global laboratories.
Their important downstream test work has already commenced aimed at replicating the previous excellent purification results and importantly, demonstrating spheroidisation and battery performance.
