-- Patriot Battery Metals (PMET.TO) 於週日晚間宣布,已成功從魁北克省 Shaakichiuwaanaan 礦區的 CV5 偉晶岩中生產出高回收率、高品位的鋰輝石精礦。 該公司利用重介質選礦 (DMS) 中試裝置,從 CV5 偉晶岩中生產出 4.47 噸高品位鋰輝石精礦,其氧化鋰含量為 6.09%,鐵含量低至 0.58%,回收率高達 89.0%。 該專案名為“ApplePick”,利用了位於 CV5 主露頭下方冰層附近的多個大型棱角分明的礦化巨石,這些巨石在現場破碎後,作為高品位原料運往 SGS(萊克菲爾德)進行重介質選礦中試裝置的加工。 該公司表示,此次生產的精礦進一步證明了其提出的 Shaakichiuwaanaan 礦區僅採用重介質選礦製程的加工方案的潛力。 此方法無需鑽探即可快速、經濟高效地大規模生產鋰輝石精礦。 試驗計畫產生的二甲基硫醚(DMS)尾礦流也為目前正在進行的鉭回收可行性研究計畫提供了原料。 鑑於「蘋果採摘」(ApplePick)計畫的成功,該公司計劃啟動「漿果採摘」(BerryPick)項目,目標是採集地表銫沸石樣品,用於更大規模的試點測試和精礦樣品製備。
