1. Developments in synthetic magnesia production Paul Schipper, Managing Director Nedmag Industries

2. Nedmag Market leader in synthetic DBM

3. Nedmag Product Range nedMag 99 high purity synthetic DBM oxide Important raw material for refractories for the cement and steel industry nedMag C Magnesium Chloride solids & solutions Used in a wide range of applications, from industrial processes like textile finishing and catalyst production to the production of feed and food additives Nedmag is a competitive and reliable supplier of de-icers throughout the world Due to its very hygroscopic character, it is one of the most effective dust suppressants nedMag Ca Calcium Chloride solids & solutions Used in drilling mud in oil & gas industry, as dehydration agents, as dust suppressants, as de-icers Effective de-icer used for melting ice and snow (lowest freezing point), widely used in prewetting salt Effective agent for dust control and has properties making it ideal for maintaining unpaved roads nedMag H industrial grade Magnesium Hydroxide Sold in suspension and in powder form, mainly used in the production of paper coatings, in pulp bleaching, as friendly alkali to neutralize acidic waste water streams and to treat acidic flue gasses

19. Consistency Focus on: Technology Raw materials (brine and dolime) Automation Process control Investments over € 1 500 000 per year

20. Consistency:major characteristics very stable over time CaO % < 0,8% every year CaO % in nedMag 99 (yearly average)

21. Consistency:major characteristics very stable over time SiO 2 % < 0,15% every year SiO 2 % in nedMag 99 (yearly average)

22. In cement applications, Nedmag has the best product Very low lime content < 0.9% (to prevent formation of low melting calcium aluminates) Very homogeneous distribution of lime (higher lime content cannot be corrected by higher silica content, because lime silicates are not stable enough to prevent formation of calcium aluminates) High magnesia content 98.5% High density 3.4 (low porosity to prevent infiltration of alkali and of lime from cement clinker)

23. Nedmag is exceptional in Mag-Spinel Bricks due to low lime and high magnesia CaO (%) MgO content (%) Source: Value Added Europe NEDMAG 99 PPL Kümas Extra QMAG HFE Magnesita M30 QMAG Extra QMAG Super Chinese Best DBM Penoles

24. In steel applications, Nedmag product is excellent Very homogeneous High magnesia content 98.5% High C/S ratio > 6 High density 3.44 nedMag product can partially replace fused magnesia in MgOC bricks

25. Choice of synthetic DBM supplier depends on technical requirements, specific to each application Nedmag synthetic DBM especially fit for MagSpinel products in Cement applications, Excellent fit for MagCarbon products in Steel applications
