5 A snapshot of our benchmark technologies Half of the world's pyrometallurgical primary copper is produced with Outotec Flash Smelting One-third of the world s hydrometallurgical copper is produced with Outotec SX-EW Over one-third of the world s sulfuric acid capacity runs on Outotec technology Most of the world's iron ore pellets are produced using Outotec's traveling grate process

6 Solutions for phosphate mining & processing Mining solutions Beneficiation solutions including gravity separation, flotation and comminution Sulfuric acid plants World s largest sulfuric acid plants have been built by Outotec Highest energy efficiency for steam and electricity generation Calcination plants Calcination with multiple energy recovery stages for high impurity ores may include cadmium removal Services Vanadium catalyst screening

7 Fluidized bed based processes Incineration - gasification

8 Agenda 1. Introduction to Outotec 2. Technology and expertise 3. Motivation 4. Resources & processes 5. Challenges Outotec has been ranked twice* to be 3 rd most sustainable of all listed companies of the world! Corporate Knights, World Economic Forum Davos Annual Conferences * In 2013 and 2015 (and in TOP 10 in 2014)

9 The key to over-fertilization is P-concentration! If you have too much phosphorus-rich waste and not enough cropland nearby consider incineration! Gasification = Concentration 1,5 t P 2 O 5 1,5 t P 2 O 5

10 Sewage sludge to energy State Zürich facility Converts tonnes per year of dewatered sludge from Zürich State to MWh/y electricity and MWh/y to district heating. 93.9% of Zürich s population voted in favor of new mono sewage sludge incinerator in a referendum! Designed and engineered for downstream phosphorus recovery!

12 Resources & recovery processes Relevant secondary P-flows in the EU28 ASH DEC Process Manure 140 Mt DS 5MtP 2 O 5 Sewage sludge 12.5 Mt DS 750,000 t P 2 O 5 Biogas (SNG/LNG) Plug- Flow digestion 7-8% DS II. Dewatering 25-30% DS III. Drying 45-95% DS SNG, steam, electricity IV. Thermal Conversion 100% DS Secondary residues V. Ash processing Animal byproducts cat Mt DS 450,000 t P 2 O 5 N Ammonium-sulfate K + PK struvite Ash as Raw material Raw material P(K)Fertilizer Process steps necessary to obtain ash as a phosphate concentrate for transportation and further processing Renewable energy yield (technical potential) of EU28 manure: 583 TWh (2,100,000 TJ) = 3-5% of total European energy supply

13 Steam Dryer Well known principle CLS Dryer is used in several industrial scale applications

14 High efficiency drying closed loop steam dryer RTD Project DEBUGGER: Energy efficient steam dryer, <400 kwh /t H 2 O

15 Steam Dryer Water vapour (moisture from material) Wet Material Heat Conventional Dryer Dried Material

16 Steam Dryer Wet Material Heat Steam 20 bar CLS aclosed Loop Steam Dryer No water vapour, no heat lost (evaporation) Hot water condensate (moisture of wet material) Heat Steam 5 bar Dried Material

17 Steam Dryer Main advantages: Energy efficient Completely closed process (no fugetive emissions) Other substances/nutrients available in the separated condensate No need for a gas cleaning stage (odour, emissions) Low internal energy consumption Mechanically few components ATEX safe (steam environment) Able to dry to to high levels (>90%)

18 CLS Dryer An Outotec project for building a larger Demonstration Plant Supported by LIFE+ and KIC Innoenergy
