1 uperfloc Flocculants & Coagulants TECHNOLOGY ENGINEERED TO IMPROVE THROUGHPUT, ENHANCE YIELD AND OPTIMIZE PROCEE IN MINING The mining industry consumes large quantities of water. With water scarcity issues on the rise and ore quality on the decline, finding a solution to effectively separate ore and gangue materials is important in lowering your total cost of operations. We offer a complete flocculant and coagulant product portfolio engineered to improve throughput, enhance yield and optimize your processes in mining applications. HIGH-QUALITY FLOCCULANT & COAGULANT We manufacture uperfloc high-quality flocculants and coagulants used in a wide range of mineralprocessing applications. Our global network of manufacturing plants utilizes computer process control to ensure consistent quality and achieve compliance with regulatory requirements. Our continual emphasis on new technology combined with applications expertise provides costeffective solutions in your daily operations. When you partner with Kemira you work with a solutions provider with the world s largest supply of inorganic coagulants. Additionally, you collaborate with a leading manufacturer of polyacrylamide polymers, with full back-integration to acrylamide and extensive polymer manufacturing capabilities. Experienced Research & Development staff along with our Applications Experts and Technical ales Representatives are available for consultation. They can assist in the selection of the optimum flocculant and coagulant solution for your mineral-processing needs.

2 Every mineral slurry exhibits a range of particle sizes and charge requirements. Optimum dosages can be achieved and overall performance improved by matching molecular weight and charge to the unique characteristics of the slurry. Our uperfloc line of mineral-processing products covers a wide variety of ionic charges, molecular weights, chemical types and physical forms.

3 HIGH-QUALITY DRY POWDER FLOCCULANT Kemira s uperfloc dry powder flocculants exhibit consistent quality and high active polymer content. Our proprietary sieving process serves to eliminate many dust fines and reduce human exposure and slippery residue in the makedown area. Together with our dry polymer process, which achieves high molecular weights, this often results in a lower overall cost in many mining applications. Powder flocculants are differentiated by molecular weight and charge density. Anionic charge density can range from 0-100%. Molecular weight can range from 1 20 million Daltons and is characterized indirectly by tandard Viscosity measurements. Kemira also produces a full range of cationic dry powder flocculants that can be useful in mining applications. Our products are free of nonylphenol and all nonionic and anionic powder flocculants contain less than 500 ppm of acrylamide residuals.

4 HIGH-PERFORMANCE EMULION FLOCCULANT We manufacture an extensive range of high performance emulsion flocculants designed to lower your overall cost in many mining applications. Years of manufacturing expertise and control of acrylamide feedstock quality have earned us a reputation for high-quality emulsions. Our proprietary emulsion breaker and carrier systems result in reduced polymer emulsion settling rates and low formation of insoluble material. Emulsion flocculants are differentiated by molecular weight and charge densities. Our uperfloc product line offers hydrolyzed anionic emulsions with exceptionally high molecular weight. Molecular weight can range from 1 60 million Daltons and are characterized indirectly by tandard Viscosity measurements. Kemira also produces a full range of cationic emulsion flocculants that occasionally find application in mining.

6 We offer a range of liquid organic cationic coagulants. Our polyamines often replace or reduce the use of inorganic coagulants for turbidity reduction in process or wastewater streams. Poly diallydimethyl ammonium chloride (PolyDADMAC) is often used in filtration applications or in conjunction with our flocculant products. PolyDADMAC or cationic polyamines can also be used in combination with our flocculant products to lower overall treatment costs. Our portfolio of coagulants also includes inorganic coagulants in various concentrations in liquid or dry form.
