Sulphydryl collectors are used for the ﬂotation of sulphide ores. Sometimes a combination of various types of sulphydryl collectors having different functional groups are used to improve the ﬂotation performance. Usually UV spectrophotometry technique is used to quantify the unabsorbed amount (residual concentration) of single sul-phydryl collectors left after the adsorption or ﬂotation studies. When a mixture of these collectors is present, UV spectrophotometry gives erroneous results as there is an interference of the spectra over the other. An alternative approach, ion-pairing chromatography (high performance liquid chromatography) gives encouraging results. This practice utilises the separation of chromatograms and determines the concentration of sulphydryl collectors spectrophotometrically. It can effectively quantify the mixtures of sulphydryl collectors of different functional groups and thus estimates the amount of chemicals needed for effective ﬂotation, and also minimises the adverse effect of the same on the environment.
