The potential for gravity separation can be illustrated by dividing particles analysed by QEMSCAN into size and density categories. This was achieved by importing data from false colour images generated by QEMSCAN in to Mathworks Matlab 2017b. Within the software, the diameter of each particle was calculated as the minor axis of the …Web

The content of Sb (atomic percent) in the Pb-Sb alloy was reduced from 1% to less than 0.01% (atomic ratio). The recovery principle lies in the different alloying potentials between Ca-Sb and Ca-Pb. Hence, molten salt electrolysis is a promising separation method to recover pure Pb from spent Sb-containing Pb alloys.Web
