A proper choice of reagents quality and quantity has a great influence on the flotation process effectiveness. Attempts to develop a method to create sodium xanthates blends used as a collector for copper sulphides flotation was undertaken at the Division of Concentrators of KGHM Polska Miedz S.A. Laboratory tests involving different blends of sodium xanthates were performed followed by the data analysis of the results. The obtained results proved that it was profitable to prepare a blend consisted of the so called “weak” and “strong” xanthates with a minimum difference in the alkyl chain length of two carbon atoms. The results of research will be helpful for development of specific xanthates blends dedicated to technology applied at KGHM under industrial conditions
