The mine design, geotechnical review and scheduling has been completed by Bara Consulting of Johannesburg Bara.Geotechnical data was transformed into rock mass quality by using classifications such as Rock mass rating RMR8.Geological Strength Index GSI and Q index Q and Q.Laboratory testing of core samples included uniaxial compressive strength with elastic moduli UCM, triaxial compressive strength TCS, indirect tensile strength UTB and base friction angle direct shear tests BFA.The output information from the geotechnical characterization phase was used to derive the underground mine method and design criteria.The geometry of the payable ore is largely flat or shallow dipping and massive enough to mechanise using long hole open stope mining. Iso 17025 Quality Manual Sample . An evaluation was completed to establish the achievable extraction ratios with and without backfill, based on the geotechnical design criteria including pillar sizes and stope spans see above.The preferred option was to mine with pillars support only, negating the requirement for a backfill plant.The payable ore will be split into blocks approximately 9.The bottom of each block will be accessed in the central position by an access crosscut and the block will be developed from the centre to the strike limit by drifting.The stope will then be mined on retreat from the block limit, retreating to the access cross cut position.The stopes will be a maximum of 1.Access to the stopes will be by footwall drives developed in the footwall at 2.All stope access crosscuts will be developed out of the footwall drives.The mine will be accessed by a twin decline system.A conveyor will be installed from the underground primary crusher on 5.Elevation to surface in the conveyor decline.The second decline will be used as a service decline for men, material and as an intake airway.The modifying factors used to generate the mining inventory used in the study from the Indicated Mineral resource are Un planned dilution 3 Un planned ore loss 3 Exclusion zones, any ore within 7.In the northern areas where mining occurs below the village the crown pillar exclusion was inc A cash margin of a minimum of 3.This margin was calculated using the operating costs, recoveries and metal prices used in the study.Underground infrastructure designs take into consideration the life of mine plan and aims to support the underground mining production and development activities.Surface infrastructure supports the mine plan with consideration of the labour and mechanised equipment requirements of the operation in addition to the movement of rock, men and materials.The infrastructure is divided into two distinct areas, with the area at the portal servicing the initial development requirements and the second servicing the production phase.Please refer to the announcement on the European Metals Website for Figure 1 Mine Design and Schedule www.Processing. European Metals approach for operation of the project as a whole is to provide a constant feed rate of 3.LCP. The Comminution and Beneficiation plants will therefore vary operating hours to accommodate fluctuations in the mine feed grade, to produce the required level of mica production.Processing Testwork.Front End Comminution and Beneficiation Testwork.This phase of testwork concerned the beneficiation of primary crushed ROM ore, by primary comminution followed by concentration of zinnwaldite by wet magnetic separation to produce a mica concentrate, which is further treated by the downstream lithium carbonate plant.Liberation Across all lithologies the lithium bearing mica, zinnwaldite, is effectively liberated from the gang material with a top end particle size of less than 3.Initial liberation analysis was supported by Heavy Liquid Separation HLS of minerals from each of the various lithologies.This was followed by detailed liberation, mineralogical and petrographic analysis using QEMSCAN of SAG milled composites with a P8.These results confirmed those from the HLS tests.Lithium Concentration Initial studies investigated both froth flotation and magnetic separation for concentration of zinnwaldite.Magnetic separation was proven to be far superior 9.PFS. To ascertain the performance of the chosen method and to allow finalization of the circuit, two composites where produced to reflect a high grade and low grade lithium ROM feed.A pseudo lock cycle flow sheet was implemented to test the effects of variability of grade and the effects of improving lithium recovery via scavenging.The results showed that an additional Wet High Intensity Magnetic Separation WHIMS stage could be used to upgrade the para magnetic material to produce a scavenger magnetic fraction, which is sent back to the start of the circuit.The testwork has resulted in an estimated lithium recovery of 9.The cleaner magnetic concentrate was reground and passed over a shaking table to recover liberated tin.The gravity concentrate and the scavenger concentrate are returned to the beginning of the circuit.A lock cycle gravity testwork program was conducted to simulate the gravity recovery circuit component of the FECAB plant.A pre concentrate grade of 8 Sn was produced with an Sn recovery of 8.A dressing circuit was approximated for the testwork by using a Mozley Super Paner centrifugal separator.SAGability testwork was conducted at ALS on the three primary lithologies.Cinovecs ore was determined to be amenable to single stage SAG milling, which forms part of the FECAB comminution design.
