Sarytogan Graphite Ltd (ASX:SGA) has succeeding in producing a concentrate grading of more than 90% TGC (total graphitic carbon) through metallurgical work on ore from the company’s namesake project in Kazakhstan.
The company has been conducting ongoing metallurgical variability tests on ore from the Sarytogan Graphite deposit, located in Kazakhstan’s Karaganda region, with this material – taken from the Central Graphite Zone (CGZ)- producing a concentrate between 90.5% and 91.3% TGC based on flotation test work.
Earlier flotation work had focused on composite samples from the Northern Graphite Zone (NGZ) and CGZ, achieving 81% to 85% TGC.
The much better result from CGZ alone involved 3 samples, and produced the high-grade TGC at higher recoveries of 84.7% to 86.8% on all 3. This is expected to boost the marketability of Sarytogan’s concentrate, which was previously known as Micro80C.
Managing director Sean Gregory said the result would a boost to ongoing development work on the project.
“The achievement of greater than 90% TGC in flotation concentrate from the CGZ is a great
achievement,” he said.
“The higher grade is expected to open this product to a broader market and potentially higher prices.
“These improvements will be validated with further tests for integration into the Definitive Feasibility Study underway.”
Sarytogan Graphite has been trading at 4.1 cents.
