#REE #Inventory Information- Protection Metals (TSX-V: $DEFN.V; OTCQB: $DFMTF) Up to date Beneficiation Outcomes Verify the Manufacturing of a Excessive Grade Flotation Focus at Excessive Restoration; @defensemetals
Vancouver, British Columbia – October 10, 2023: Investorideas.com Newswire, –Mining/Metals/ Inexperienced Vitality Inventory news- Protection Metals Corp. (“Protection Metals” or the “Firm”) (TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) is extraordinarily happy to report the latest outcomes of the in depth comminution and beneficiation take a look at work that has been performed by SGS Canada Inc. in Lakefield, Ontario (“SGS”) on variability samples from the Wicheeda Uncommon Earth deposit.
Learn this information, that includes DEFN in full at: https://www.investorideas.com/information/2023/mining/10101DEFN-Beneficiation-Outcomes.asp
Craig Taylor, CEO of Protection Metals, said: “Our current outcomes exhibits that the Wicheeda feedstock might be crushed, floor and floated to provide a uncommon earth flotation product with related or higher recoveries and grades to the highest producers globally. Our mission has many favorable circumstances for fulfillment: mineralogy, metallurgy, infrastructure, and neighborhood collaboration additional supporting a path to manufacturing.”
Beneficiation Outcomes
· A complete of 90 open-circuit flotation assessments, utilizing 1 or 2 kg of feed, have been performed on seventeen particular person variability samples, numerous composites and blends. Contemplating all open-circuit flotation assessments, at a feed grade of three% TREO (Whole Uncommon Earth Oxide), the most effective match line indicated 80% restoration to a forty five% TREO focus. Closed circuit operations, as practised in flotation crops, might be anticipated to ship larger restoration and grade.
· Along with the smaller-scale assessments, 29 bulk flotation assessments utilizing 10 or 12 kg costs have been accomplished to each additional optimize parameters and generate 16 kg of 46% TREO content material with a restoration of 78% to be used as feed for hydrometallurgical assessments.
· Very beneficial outcomes have been obtained in a locked cycle take a look at on a deposit composite giving a restoration charge of 85% of the uncommon earths at a focus grade of fifty.7% TREO.
The beneficiation assessments have been aimed toward confirming the reagent suite and working parameters developed in earlier testwork and within the 2020 flotation pilot plant operated on a 26t bulk pattern. The variability samples responded properly to the flowsheet and the chosen reagent suite and working regimes (temperature, density). Particulars of the testwork are offered beneath.
Comminution Outcomes
· SMC and Bond comminution assessments have been full on all variability samples. The current work confirms, and considerably expands on, the info obtained through the 2020 pilot plant work.
· The info point out that grinding power will likely be comparatively low, specifically within the higher parts of the deposit when the softer dolomitic carbonatite (DC) materials, with a Bond ball mill work index of 9 kWh/t, is almost all of the potential mill feed.
· Autogenous or semi-autogenous grinding system adopted by a ball mill will likely be very passable for the Wicheeda comminution plant.
John Goode, Consulting Metallurgist to the Firm, commented: “SGS has carried out a really thorough investigation of the comminution and beneficiation traits of all kinds of samples from the Wicheeda deposit. The brand new outcomes are near these reported earlier and utilized in earlier research. Grinding power necessities have been proven to be comparatively low and flotation restoration and focus grades are excessive and really beneficial.”
Methodology
The three key uncommon earth-bearing lithologies within the Wicheeda deposit are, (1) the higher-grade dolomite carbonatite (“DC”) which makes up 73% of the deposit, (2) the xenolithic carbonatite (“XE”) that represents 24% of the deposit, and (3) the syenite (“SYN”). Primarily based on its close to floor location, the DC materials is predicted to comprise the vast majority of the mill feed and the XE and SYN lithologies deeper within the deposit mined later. The first uncommon earths minerals are monazite, bastnäsite and synchysite/parisite.
The comminution and beneficiation assessments have been achieved at SGS by a group headed by Dr. Jing Liu, Senior Metallurgist. Take a look at materials comprised a 260 kg Grasp Composite and seventeen variability samples, every nominally 36 kg, ready from drill core and representing the three most important lithologies within the Wicheeda deposit. The variability samples have been chosen to cowl the three dominant lithologies, a variety of grades (1.1% to 4.5% TREO), depths (7 m to 221 m down-hole), and places within the deposit, (for extra outcomes on completely different grades and lithologies please see information launch dated October 11, 2022 and February 14, 2023). In depth mineralogy was accomplished on the samples and take a look at merchandise to raised outline the deposit and course of outcomes.
A complete of 90 open-circuit flotation assessments, utilizing 1 or 2 kg of feed, have been performed on a DC composite, xenolithic and syenite composites, the person variability samples, the Grasp Composite and numerous different composites and blends. At a feed grade of three%, the most effective match line signifies 80% restoration to a forty five% TREO focus. Closed circuit operations, as in a flotation plant, would ship larger restoration and grade. The lower-grade XE and SYN materials which can be anticipated to be encountered late in potential mine life delivered considerably decrease focus grades and recoveries.
Three locked-cycle assessments have been accomplished, with LCT-3 operated on 12 kg batches of a New Grasp Composite made up from all variability samples blended based on the lithology distribution. The flowsheet, illustrated in Determine 1, was operated over seven cycles and confirmed good stability. The feed grade to LCT-3 was 2.9% TREO and the focus assayed 50.7% TREO with a restoration of 85.4%.
Determine 1: LCT-3 Flowsheet
Comminution take a look at work was accomplished by SGS utilizing normal Bond comminution assessments and the SMC take a look at which measures the competence of main grinding mill feed. The SMC outcomes have been offered to JKTech for interpretation. The Bond ball mill work indices have been 9, 11, and 13 kWh/t for the DC, XE, and SYN samples respectively. The SMC report categorized the DC samples as being very tender and the XE samples as medium.
