October 7, 2020 (Source) — Avalon Advanced Materials Inc. (TSX: AVL) and (OTCQB: AVLNF) (“Avalon” or the “Company”) is pleased to provide an update on its Separation Rapids Lithium Project (“Separation Rapids” or the “Project”), situated approximately 70 km by road north of Kenora, Ontario. Since Avalon’s news release dated June 3, 2020, metallurgical testwork has been progressing on several fronts with the overall objectives of reducing costs, improving recoveries and optimizing lithium product quality. The Company is continuing to look at market opportunities to serve both the glass-ceramics market with its lithium mineral (petalite) product and the lithium battery materials market with its high purity lithium hydroxide product.
In its 2016 Preliminary Economic Assessment, Avalon developed a proprietary process flowsheet to produce a high purity lithium hydroxide product from petalite for the lithium battery material market. The flowsheet has the advantage of generating limited waste by the recycling of the sulphuric acid solvent. To further optimize this flowsheet, Avalon has shipped a 50 kg sample of petalite concentrate to XPS (Expert Process Solutions) in Sudbury, Ontario to generate leach solution for use in optimizing the final stages of the process, which involves the use of electrolysis to produce lithium hydroxide. The program will focus on an improved membrane alternative and efficient crystallization of the final high purity product. The results will enable finalizing equipment selection and design.
With Ontario Premier Doug Ford recently announcing Ontario’s interest in establishing new battery materials supply chains in the province, Avalon is investigating collaborative opportunities to establish a lithium processing facility in Northwestern Ontario. The facility being planned would produce lithium hydroxide, and would also accept concentrates from other producers of lithium minerals from the many pegmatite deposits that occur in northern Ontario.
In the glass-ceramics market, the innovation of new products is creating many new market opportunities for Avalon’s petalite product. One such market requires a petalite product that has not been concentrated by froth flotation, as residual reagents on the surface of the product can compromise its performance in this specific glass-ceramic material. Recent testwork conducted at Met-Solve Laboratories, Langley, BC has successfully demonstrated that an acceptable quality petalite product to serve this market can be produced simply by using dense media separation. The Company’s next step is to generate a larger product sample for evaluation by the customer that expressed interest in it.
Other testwork underway is focused on ways to reduce processing costs and energy consumption, including alternative milling technologies. Samples from three mineralogical sub-zones within the main Separation Rapids resource have been sent to Selfrag AG in Switzerland, for testing using their patented electric pulse disaggregation (“EPD”) process. EPD uses high voltage electrical pulses to fragment broken rock along internal mineral grain boundaries. The result is a crushed mass of single mineral particles, as opposed to the less selective breakage that occurs with traditional mechanical comminution methods. Avalon believes EPD is the most relevant alternative milling method for reducing over-grinding and improving overall petalite recoveries as well as reducing energy consumption.
In June, Avalon received the necessary approvals to proceed with the 2,500 tonne bulk sample extraction program originally planned for 2019. The COVID-19 lockdown delayed implementation of the program but Avalon does have sufficient inventory of sample material for its present needs. The Company now intends to proceed with the additional bulk sampling work later this year after freeze-up. Planned upgrades to the access road will be undertaken in 2021.
