Ongoing Outotec Horizon2020 projects for sustainable use of complex mineral resources
Outotec Horizon 2020 project portfolio for complex raw materials Complexicity in mineral resources can mean for example Low grade deposits Low tonnage deposits Tailings and waste materials Complex mineralogy (e.g. acid consuming, refractory valuables) High relative amount of impurities in mineralogy (e.g. arsenic, antimony) Ore bodies with a large variety of valuable metals making long processing chains Key challenge to adress is the economic and environmentally sustainable use of these complex mineral resources Process development, but also equipment solution development needed to enable sustainable business cases Modularity as an enabler
Modular solutions as enablers for economic utilization of complex mineral resources
Typical benefits of modular plant units Reduced overall project delivery costs and time by minimizing site activities Less labor Ease in pre-commissioning and installation construction project vs. installation project Minimal civil engineering Compact and small footprint Ease in expansions (phased development possibility) Reuse potential of modules

VSF X modularized solvent extraction
VSF X Plant INTRODUCTION Modularized revolution for efficient solvent extraction Outotec has been developing a wide range of solvent extraction technologies for decades and is now introducing the new Outotec VSF X Plant. Standardized and modularized Outotec VSF X Plant provides a novel way to design, manufacture, transport, install, operate and maintain SX-plant far better than in the past with highly sustainable and safe methods For the customer this means fast-track projects with savings in means of time, costs, quality and operation.
VSF X Plant INTRODUCTION Solutions brought by VSF X Plant: Challenge Long response times Prolonged projects Exceeded budgets Solutions not always the most feasible for the purpose Quality varies case by case Environmental legislations and regulations are becoming tighter, requiring more and better documentation concerning the operational and environmental safety. Solution Predesigned and standardized plants and modules Preselected manufacturers, partners and implementation methods. Fast-track delivery Total delivery, total response by Outotec. Tested, standardized products and concepts. All the costs are known. Product delivery instead of project delivery Outotec SX knowledge is automatically built-in State of the art QA/QC documentation and implementation VSF X Plants are designed with minimizing its enviromental impact and carbon footprint as well as ensuring the sustainable and safest possible working condition for the operators. Proven enviromentally sound technology
VSF X Plant TECHNOLOGY DESCRIPTION: Solvent extraction process: Intake of two phases, organic and aqueous (PLS) Mixing of two phases and dispersion forming Dispersion enables mass transfer of metal ions Gravity separation of two phases in settler Stripping of metal ions from loaded organic in next stage End-product: pure concentrated solution suitable for metal recovery VSF X Mixer-Settler based on upgraded Vertical Smooth Flow technology, the superiority of which has been proven over decaces
VSF X Plant BENEFITS Outotec is the only technology provider that offers highly predefined but still tailor-made total delivery package based on customers' needs. 25% shorter lead time from contract to production, through pre-defined product, manufacturing, transportation, site logistics, minimized site work and pre-comissioning activities Small size mixer-settler (max dispersion flow 160 m3/h)
VSF X Plant BENEFITS Installation of normal size mixer-settler (dispersion flow 320 m 3 /h)
Modular Organic and Crud Treatment Preassembled and fully equipped modular organic and crud treatment plant unit
Results: CAPEX Costs Conventional settler VSF X settler 0 4 8 12 16 20 24 Time (months) Best case scenario: 24% lower CAPEX for EPC delivery Savings mainly from construction and installation
Results: Cost Structure Conventional settler 5% VSF X settler 2% 50% 29% 11% 15% 72% Engineering Equipment Construction Installation 16% Moving emphasis towards prefabrication Lower project risks and cost uncertainty From construction project to equipment installation
DispersionSense, next step in SX process control A view inside of a settler showing phases of Organic/Dispersion & Dispersion/Aqueous - Solving the blindness problem Monitor the process and predict problems On line information enables process optimization with long time history data Increase field operators safety Short pay back time Organic - Dispersion interface Dispersion - Aqueous interface
