SGS Canada Will Complete Pilot Work
Piedmont Lithium Limited (ASX:PLL) is partnering with SGS Canada, Inc. in Ontario to complete a pilot-scale spodumene concentrator testwork programme using a bulk sample collected from the Piedmont Lithium Project in North Carolina.
The company collected over 50 tonnes of mineralised pegmatite from 17 locations across the company’s Core Property in February 2020. Samples were collected from near surface pegmatites located in areas of early, middle, and late year production.
The pilot plant design will be based on the results of prior testwork programmes and will be used to support both definitive feasibility study of the company’s planned concentrate operations as well as detailed design engineering of the full-scale operations.
The pilot programme will target production of a large sample of spodumene concentrate with at least 6.0% Li2O and less than 1.0% Fe2O3 for use in future pilot-scale lithium hydroxide testwork programmes that Piedmont will complete as part of Definitive Feasibility Study of the company’s planned integrated lithium chemical plant.
President and CEO, Keith Phillips, said the pilot scale testwork is viewed by the company as a critical step in ensuring future commissioning and ramp-up success.
Additionally, the bulk sample collected targeted a range of potential concentrator feed conditions, including low-grade zones and diluted feed.
Mr Phillips said testing variable conditions rather than an optimised feed will help inform engineering design and eliminate potential operational bottlenecks during the project design phase.
“We are pleased to continue our partnership with SGS Canada on this important pilot-scale testwork programme, which will underpin our upcoming definitive feasibility study as well as future detailed design engineering of our spodumene concentrator,” Mr Phillips saidl
“The programme will enable Piedmont to complete future lithium hydroxide testwork programs and also supply large samples of spodumene concentrate to our key customer, Tesla, for their own testing purposes.”
