Cytec is committed to partnering with our customers to meet their needs. Our network of technical staff provide on-site technical assistance worldwide. We are dedicated to on-time delivery, even to the world's harder to reach areas. Our unique approach to servicing our customers has made Cytec the leading provider of reagents to the mining industry.

PROMOTERS AND COLLECTORS

AEROFLOAT®, AEROPHINE® and AERO® promoters are used for the flotation of a wide range of sulfide and industrial minerals. These products also enhance the recovery of fines and reduce ash content in coal flotation.

AERO 5000 Promoters provide mineral processing engineers with a complete set of tools based on novel chemistries that provide improved performance compared with traditional sulfide collectors – including faster kinetics, better selectivity in complex sulfide separation, effectiveness at lower alkalinity, neutral circuit promotion (NCP), increased precious metals recovery and improved gangue sulfide recovery.

AERO 6000 promoters are alkyl hydroxamate-based collectors designed for industrial mineral and oxide flotation. These are based on a new, patented manufacturing process that provides stable, highly effective products with good economics. Applications for AERO 6000 promoters include improving kaolin clay brightness, increasing recovery of oxidized sulfides, improving gold recovery and producing higher-grade silica sand.

Featured products: AERO 6493, AERO 6973, AERO 6494 promoters

AEROPHINE® promoters are manufactured based on phosphine chemistry (PH3), making them unique among sulfide mineral flotation reagents.

Benefits include:

• Increased recovery of precious metals
• Higher recoveries and selectivity in complex ore flotation
• Higher selectivity against pyrite
• Substantially reduced dosage rates
• Stability and avoidance of hazardous decomposition products
• Low environmental toxicity

FROTHERS

Cytec’s line of AEROFROTH® and the recently integrated OREPREP® frothers include both alcohol- and glycol-based products formulated for optimum effectiveness in all types of flotation systems. This complete line of products, in conjunction with Cytec’s unique collector/depressant chemistries, provides the tools for technical innovation and problem solving in the field.

DEPRESSANTS

Cytec’s research in the area of polymer depressants has resulted in the commercialization of advanced, functionalized polymeric dispersants based on polyacrylamide chemistry. These new products show superior performance of these polymers over other depressants – such as those based on inorganic or natural products. This is a continuing area of R&D activity for Cytec.

Featured products: AERO 7260, 7261 and 7662, AERO 8860 depressants

FLOCCULANTS

Cytec’s high performance CYFLOC™ flocculants represent the state-of-the-art in chemistry for liquid/solids separations and selective flocculation. These products provide better separations, fast settling rates and clearer overflows across a wide range of mineral processing applications – resulting in increased throughput and product recovery. Current research at Cytec has resulted in higher molecular weight products and products with an even anionic charge distribution. CYFLOC™ flocculants are available in dry, emulsion and liquid forms.

Featured products: CYFLOC™ 1260 flocculants

ALUMINA PROCESSING CHEMICALS

Cytec offers most of the key products required to service the Bayer process.

Featured products: CYFLOC™ HX flocculants; CYFLOC™ dry and emulsion based washer flocculants; CYFLOC™ HX 800 filter aids; CYFLOC™ hydrate flocculants; AERODRI® dewatering aids; CYQUEST® defoamers, humate and iron removal agents

FILTER AND DEWATERING AIDS

AERODRI filter aids increase filter throughput in mineral processing by reducing moisture content and improving release of the filter cake. They are often used to improve coal grade by increasing the BTU rating through reduced moisture content. AERODRI dewatering aids offer unique chemistry that can significantly increase production rates and lower energy and transportation costs.

METAL EXTRACTION PRODUCTS

Cytec metal extraction products has a simple approach to doing business: if our customers are successful, then we will be successful. In order to reach this common goal, Cytec collaborates with mining companies to ensure that they get the most metal at the least operating cost.

We do this by providing superior support that addresses our customer's site specific needs. Our on-site application technologists ensure that our customers receive best extraction performance. We offer technologies and service that:

• Optimize metal transfer
• Provide superior selectivity of copper over iron, or cobalt over calcium and magnesium
• Decrease the cost of your operations
• Allow you to process difficult ores
• Optimize the use of natural resources
• Minimize waste
• Strengthen and support your technical team

New offerings from Cytec that accomplish the above include the following.

ACORGA® NR series and ACORGA OR series of products have been developed to provide higher degradation resistance in Cu SX circuits that have occasional or consistent exposure to high nitration or oxidative conditions. With these products you know your valuable extractant inventory is protected. This added peace of mind and reliability are unique to Cytec's new Cu extractants.

CYANEX® 600 is used to recover Mo from moderate to high volume acidic streams which contain low concentrations of Mo. Use of this product and our unique process allows economic recovery by concentrating Mo by over 1000 times. This allows existing Cu SX operations and other operations to get an additional revenue stream from already processed ore or from bi-products that contain Mo.

Ni/Co modeling - Cytec can now model the separation of Cobalt and Nickel via solvent extraction in order to optimize the design of a future operation or to substantially improve the efficiency of an existing operation. This technical support is available to our contracted customers. Higher profitability is another reason why Ni/Co SX should be your first choice for producing these metals versus other technologies like precipitation.
