Superconducting Magnetic Separation
Cryotechnica International has extensive expertise in the development and implementation of superconducting magnetic separation (SHGMS). SHGMS technology has been utilised in the China Clay industry since the mid-1980s for the product improvement by the selective removal of impurities. This is especially important in clays used in ceramics where simple chemical bleaching to improve whiteness is not applicable.
New applications are under development in areas such as minerals extraction from tailings dumps, environmental remediation and industrial processing.
In addition to process development, Cryotechnica has the ability to implement SHGMS on all scales from laboratory to commercial. The company's separator technology is "next generation" incorporating fully cryogen free operation. As such, Cryotechnica's separation systems are compact, easily transported and installed and require no expensive cryogens for their operation. This is especially important in applications where the customer's site is remote and in parts of the world where liquid helium is difficult to obtain.
Cryotechnica's 6 Tesla SHGMS system has a flux density of 6 Tesla in a 152mm diameter x 300mm room temperature separation space. This system offers sufficient capability for initial application trials right through to medium-scale commercial implementation. Through the development and realisation of the conduction-cooled magnet technology, Cryotechnica has positioned itself on the cutting edge of cryogen free magnet technology. The system design can be scaled to full commercial production capability. Initial markets for this technology are existing applications in the China Clay industry and new applications in mineral extraction.
