TG Metals’ Metallurgical Work Produces Quality Lithium Concentrate
THE DRILL SERGEANT: TG Metals (ASX: TG6) reported preliminary results from recent metallurgical testwork undertaken on the Burmeister deposit, within the company’s Lake Johnston lithium project in Western Australia.
TG Metals had Initial Heavy Liquid Separation (HLS) work carried out applying dry magnetic separation technology that produced quality concentrate with a lithia grade ranging from 5.34 per cent lithium oxide (Li2O) to 6.31 per cent Li2O from three drill core representative composite samples recovered from the Burmeister deposit.
“These initial sighter metallurgical testwork on the Burmeister pegmatites are outstanding and support the potential to achieve a SC6 (6.0% Li2O spodumene concentrate) concentrate utilising HLS processing technology that supports our initial assumptions,” TG Metals CEO David Selfe said in the company’s ASX announcement.
“Simple mineralogy equals simple processing.
“As we progress Burmeister, we aim to demonstrate a mineral resource conducive to open-pit mining and simple metallurgy, providing favourable economics for a spodumene lithium hard rock mining and processing operation.
“A combination of Ore Sorting and HLS technology is the preferred processing method, over other more complex mineral processing flowsheets to produce a course, quality spodumene concentrate.
“Flotation batch testwork is progressing on the combined fines and middlings size fractions of the crushed ore, and once complete, the company will have the basis of a preliminary flowsheet which is consistent with a low capital intensity approach.”
