1 Bo Arvidson Information Introductory Meeting

2 Basic Info Bo Arvidson Background MSc & Tekn. Lic (PhD) in Mineral Processing, Royal Institute of Technology, Stockholm, Sweden Specialties: Physical surface chemistry, magnetic separation, ore sorting, flotation, electrostatic separation, mineral processing flow sheet development, technical due diligence In-depth knowledge: Comminution, gravity separation, classification, sizing, rheology, plant design, project management, feasibility studies

3 Achievements - briefly Numerous patents & innovations Start-up of pyro-processing plant that commissioning team failed to do after 8 months of effort Developed an innovative light-weight aggregate production process & built commercial plant promoted to plant superintendent Developed world s largest HGMS (strongest continuously processing wet high-intensity magnetic separator) on time & on budget Developed first R-E separators & 80+ new mineral processing applications dominated new market Implemented several new ore sorting applications achieved profitability for the first time in ore sorting equipment sales history.

4 Achievements - briefly Transformed a high-loss Outotec company to a good profitable level Developed key process stage for ultra-high purity quartz production (90+% of global of UHPQ processed in my machines) Directed project to build green-field high-grade silica plant in Jordan Developed unique high-purity zircon process Resolved recovery challenge in combined high-intensity & flotation process for 3M Enhanced product recovery by 20% in a wollastonite plant Solved major issues in an iron ore project making the project feasible; innovative process development, plant design, DFS, work package manager, kept budget, critical role in commissioning, high-grade production in record time, exceeding all key criteria

5 Meren Silica Project

6 Iron Ore Experience Bo Arvidson Iron Ore Experience + 30 iron ores studied New major plant installations (including innovative processes) Australia, Argentina, Turkey, Slovakia, China, Sweden, USA. Numerous other additions & improvements in existing process plants. Modelled large iron ore plant operation by using extensive production statistics to project optimized ore type blends

7 Iron Ore Experience Sweden: Idkerberget, LKAB (Kiruna, Malmberget, Koskullskulle), Blötberget. LKAB Hematite processing seminar. Northland s Kaunisvaara ores (Tapuli, Sahavaara, Pellivuoma). Developed unique process for Sahavaara & Pellivuoma, which made the project viable. Jokkmokk Iron Mines (test mining & met. test work 2013); super grade (71.5% Fe) achieved Brazil: CVRD (now Vale), Ferteco, Samarco, MBA Australia: Hamersley and several other Angola: Hematite/limonite/goethite iron ore South Africa: Kumba (mainly hematite) China: Meishan, Jiuquan (magnetite, hematite, goethite), Tongua (hematite) USA: Cleveland Cliffs Tilden, other

8 Iron Ore Experience Canada: IOC, Wabush/Scully, several other). Mainly hematite, some magnetite/hematite Slovakia: Siderite ore Ukraine: Krivoj Rog (1978), Ferrexpo (Poltava, Yeristovo, Belanovo) India: Kudremukh, GOA iron ores, several other. Mainly hematite, some limonite and goethite. Turkey: Siderite ore Austria: Siderite ore Bulgaria: Kremikovtski siderite ore Finland: Northland s Hannukainen (magnetite, chalcopyrite, gold). Enhanced process to enable use of all ore types and not only on 1/3 of the resource. DFS.

9 Dry Processing Experience Approximately 80+ industrial minerals applications using dry highintensity magnetic separation (R-E roll and drum separators). One application designed for 1,000 tph. Hematite iron ore pilot plant at Malmberget, Sweden. Natural moisture was slightly too high (1.8%) to effectively process < 3 mm size fraction with large amount of extreme fines. Siderite iron ore in Slovakia with natural moisture. Three size fractions: 0-4 mm, 4-10 mm, mm. Occasionally 0-4 mm had too high moisture (> 2%). Magnetite/hematite/siderite/goethite raw ores in China. Three size fractions, top size 65 mm. Natural moisture no problem. Magnetite iron ore in Sweden. Pilot plant processing <11 mm size fraction at moisture up to 3.6%. Concentrate ground very fine for wet processing to achieve 70% Fe grade. Consulted in other projects involving iron ore sand.
