The Mining Chemicals Technology business of Cognis is the only supplier capable of offering the full range of SX

reagent technology (one-stop-shopping): Ketoximes, Aldoximes, Non-modifed Ketoxime/Aldoxime blends, and

Fully/Slightly Modified Blends with alcohols, esters and other patented and prorietary modifiers. This unique

position makes all reagent technology available to our customers and allows Cognis to custom blend reagents,

providing you with optimized metallurgical and physical performance at the lowest cost. No other supplier of SX

reagents has this capability.

COGNIS, supplier of LIX®Reagents and inventor of copper solvent extraction (SX), has been the recognized market

and technology leader for more than 45 years. Independent studies show LIX® Reagents are 10 - 25% more efficient

than the competitive products and are used to produce over 60% of the world’s SX copper cathode.
LIX®Reagents are produced by Cognis Ireland, Ltd. in 2 dedicated, state-of-the-art plants. As an ISO 9000 and

14001 registered facility, Cognis Ireland remains focused on safety, quality and the environment.

Cognis is the only supplier offering the full line of SX reagent technology. Our commitment to R & D continues to

bring new products and technology to further reduce costs.

Cognis’ unique MSP™ Minesite Services Program includes flow sheet development, computer modeling, plant start up

assistance, pilot plants, and operator training. Cognis’ global Teams of experts work for you to lower your

costs.

EnviroWet™ DC-100, a new and unique dust control agent, is more compatible with SX, less toxic to iron oxidizing

bacteria, highly biodegradable, reduces water consumption and is cost efficient.

Isocalc® TM ver. 6.01 - Isocalc™ modelling software generates isotherms based on chemical models or it can use

laboratory isotherm data to model series and series parallel circuit configurations for plant optimization and

new flow sheet development.
Teamwork with our customers produces superior results.

Our first priority is making sure you, our customer, succeed.

MANUFACTURING AND SERVICE FACILITIES
Cognis Ireland, Ltd. produces LIX Reagents in two, state-of-the-art plants using our patented production

processes.

Production facilities for Cognis’ Alamine® and Aliquat® solvent extraction reagents are located in Kankakee,

Ill.

NEW PRODUCTS AND SERVICES FROM COGNIS
First, Cognis has announced its line of LV or Low Viscosity copper solvent extraction reagents. This line

includes both non-modified and modified oximes, and all continue to be Low Density reagents. Both of these

properties facilitate phase separation, reduce entrainment, and allow the use of LIX® Reagents up to 50 volume

percent in the organic phase.

Next, Cognis is pleased to announce its Opti-Form™ optimum formulation software. This software allows Cognis

engineers to analyze each and every solvent extraction circuit (PLS, pH, sulfate content, stripping conditions,

staging requirements, etc.) and formulate the optimal blend of oximes and modifiers.

Next, Cognis announces its ‘Flexible Circuit’ and ‘Optimum Series-Parallel’ solvent extraction circuit flow

sheets. Both can provide savings in capital and operating costs when compared to convention circuit designs.

Finally, Cognis announces its latest version of Isocalc® TM isotherm and McCabe-Thiele modeling software. This

latest version takes advantage of the many formulations available from Cognis and it will accurately model the

new Optimum Series-Parallel circuits.
