For many years, interaction of proteins with surfactants in solution has been a subject of extensive studies. The addition of surfactants and proteins to solution leads to the formation of protein surfactant complex. The structure of these objects depends on many factors, e.g. the reagent concentrations, the type of chemical compounds used, the order of protein and surfactant addition. The aim of this work was to examine the way of adsorption of protein (chicken egg albumin) and surfactant (sodium dodecyl sulphate) on the mineral surface (magnesite rock) affects the properties of magnesite suspensions. The effect of these interactions on the flotation of magnesite has been investigated. Effeciency of flotation (yield and separation of magnesite from quartz) was higher when both SDS and albumin were adsorbed at the particle surface.

Od wielu lat prowadzone są badania nad wzajemnym oddziaływaniem cząstek białka i surfaktantu. Efektem tego oddziaływania jest powstanie kompleksu białko-surfaktant. Celem pracy było sprawdzenie, w jaki sposób kompleks białko-surfaktant, powstały na powierzchni ciał stałego, wpływa na właściwości powierzchniowe ciał stałych. W badaniach użyto, jako białka albuminy a jako surfaktantu SDS. Badania były prowadzone na skale magnezytowej z kopalni Wiry. Badano adsorpcję odczynników na powierzchni ciała stałego i flotację. Otrzymane wyniki częściowo wyjaśniają problem oraz stanowią asumpt do dalszych badań nad separacją magnezytu od krzemionki.
