These chemical systems are of importance for metallic lead refining at 330-500 °C (603-773 K), and for separation of copper from lead in complex polymetallic processes at 1000-1150 °C (1273-1423 K). Few studies are available for the solubility of solid copper arsenide in lead at low temperature. At high temperature, significant discrepancies between available experimentally measured limits of two-liquid miscibility gap exist in the Cu-Pb-As system. Experimental investigation of the present study aimed to fill the gaps and resolve the discrepancies. It consists of equilibration, quenching and electron probe microanalysis. Thermodynamic modeling helped to analyze the results and provided a database of model parameters. Present study is a part of a larger research program aimed at characterization of phase equilibria, heat balance and distribution of elements during complex copper and lead smelting, refining and recycling.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Distribution of element,Experimental investigations,FactSage,Liquid miscibility gap,Model parameters,Research programs,speiss,Thermodynamic model[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]FactSage,lead refining,speiss,thermodynamic modeling[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘The authors would like to acknowledge the financial and technical support for this research from the consortium of lead producers: Aurubis, Kazzinc Glencore, Umicore, Nystar, Peñoles and Boliden through Australian Research Council Linkage program LP180100028.
