Efficiency of Carbon Toner Removal by Double Stage Flotation
In order to investigate the efficiency of black toner removal by double stage flotation, recycling was performed on Navigator office paper printed by two different colour laser printers XEROX PHASER 7700 and LEXMARK C920. In chemical deinking by flotation the sodium laurylethersulphate as the nonionic surfactant was used. Froths collected by flotation were re-floated in purpose to increase the usage of fibers. For an efficiency evaluation of above-mentioned method, an image analysis of all formed handsheets was done. During the first flotation the removal of particles bigger than 0.07 mm2 is very well achieved, whereat some better efficiency for Lexmark toner removal was obtained. By second flotation extra removal of particles bigger than 0.04 mm2 was accomplished. Image analysis results gained on froth handsheets point out the good efficiency of carbon toner removal from Lexmark and Xerox froth suspension. These results indicate the need for froth flotation in purpose to achieve enhanced usage of fibres which were in previously done flotations removed from suspension together with impurities.
