Data of REEs (Ce, Nd, Th) analysis from Bangka tin tailing applying froth flotation method using sodium oleate and KClO3.

Abstract

This article presented the data of REEs (Rare Earth Elements) analysis from exploitation of Bangka tin tailing, Indonesia. Nowadays, REEs have broad applications in modern industry such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, fluorescent lighting, negative ion generators, and much more. A 30 min. and 400 rpm froth flotation method has utilized 0.06 M sodium oleate flotation agent, 0.07 M KClO₃ depressant, and 2.0 M HCl for pH arrangement of 10.0 g sample to analyse REEs from 170 mesh Bangka tin tailing at 25 °C. The analysis is found to be cerium (1.60 %, pH 7.0), neodymium (0.70 %, pH 7.0), and thorium (0.95 %, pH 8.0) in the collector, while at the same time, the concentrations of cerium (9.45 %, pH 7.0), neodymium (3.15 % pH 7.0), and thorium (3.90 %, pH 8.0) in the tailing (depressant) applying froth flotation method. Based on the variation of KClO₃ concentrations at the given condition (0.06 M sodium oleate, pH 7.0, 30 min., 400 rpm. 25 °C), the recovery of REEs in the collector using froth flotation method is as follows: the highest concentrations of cerium (11.80 %) and neodymium (3.93 %) were obtained at 0.005 M KClO₃ and pH 7.0, while the highest concentrations of thorium (4.50 %) obtained at KClO₃ free (none KClO₃) at the same pH. The utilization of sodium oleate flotation agent and KClO₃ depressant in the flotation REE recovery from tin tailing can be viewed as a new contribution of this study since unpublished previous work applied palmitate collector and no any depressant for REE recovery from the same mining area. The contribution of REE analysis from Bangka tin tailing applying froth flotation method is valuable for mining industry.
