title = "Cost comparison between two different two-liquid flotation methods",
abstract = "The purpose of the present work was to perform the cost comparison between two different two-liquid flotation methods to selectively recover ultra-fine fluorescent powders for material recycling. Two-liquid flotation utilizes the interface of two-liquids with different polarities (i.e. polar and non-polar solvents) and surfactant to selectively hydrophobized target particles / powders. The major difference between the two methods described in this study were the polar solvents that created the difference in recovery / separation performance of the powders. The first method used N,N-dimethylformamide while the second method applied water. Based on the cost comparison, it was found that the first method is more cost effective in order to recover the fluorescent powders with high purity.",
