Extraction Process of Lead and Variations of Physicochemical Properties using the Smelting Experiment of Galena
Year: 2013
Type: article
Abstract: This study aims at identifying the variation of physicochemical properties for galena ore in order to use it in understanding of manufacturing techniques in terms of metallurgical method and smelting or refining process for obtaining lead.The ores in the study obtained from the operating mine have been washed and pre-treated for a test.Metallic lead has been extracted by roasting process.The result displays that galena is still in present in the matt despite of exposure to high temperature, over 1000℃.Nearly 11.1g/㎤ specific gravity metallic lead has been collected from the refining test of which aim was to remove the remnant galena and a trace of concentrated silver has been identified at the grain boundary.The result suggests that at least one refining process was essential to acquire high purity metallic lead and cupellation had been executed to remove remnant silver.
