K-Technologies, Inc.

K-Technologies, Inc. ("K-Tech") is a specialized chemical technology development firm that offers unique process technology and development capabilities for the minerals and chemicals industries. In particular, K-Tech has focused on various separation processes involving continuous ion exchange ("CIX"), continuous ion chromatography ("CIC") and related advanced separation methodologies as they apply to a variety of chemical and environmental applications.

K-Tech supplies specific process technology and know-how for particular process applications, most of which involve complex separations of materials from host streams, and subsequent purification of the separated components. We design the overall process package and develop detailed design criteria, generally in partnership with specialty engineering companies and equipment suppliers in order to produce a complete project package.

K-Tech currently holds 6 US patents and intends to pursue patent applications for several of its other technologies. The following are a few examples of K-Tech's unique process technology applications developed through bench, pilot plant, and/or commercial experience:

• Uranium recovery from phosphoric acid with CIX.

• Impurity removal (e.g. iron, aluminum, magnesium, cadmium) from phosphoric acid using CIX or other extraction techniques.

• Recovery of rare earths and metals such as vanadium and cadmium from wet process phosphoric acid using CIX and CIC techniques.

• Fluoride recovery from fluorosilicic acid, phosphogypsum pond water, or cooling water, using CIX techniques and subsequent conversion of recovered silicofluoride solutions into industrial fluorides and silica products.

• Production of potassium salts via CIX processes including potassium sulfate, potassium phosphates, potassium carbonate, and potassium nitrate.

• Recovery, separation, and purification of rare earths, including Y and Sc, from pregnant leach solutions of dissolved rare earth ores using CIX/CIC techniques.
