This survey continues the long tradition of providing a snapshot of operating data from industrial electrorefineries. It is a supplement to previous surveys that were performed in 1987, 1991, 1995, 1999, 2001, 2003, 2007, 2010, 2013 and 2016. Analyses of current data and historical trends are presented. Examples of innovations to reduce costs, improve productivity, and improve quality are provided. In general, refineries continue to increase productivity while treating anodes with more impurities. INTRODUCTION This manuscript analyzes global survey data provided by operating copper electrorefineries. This paper continues a series of surveys of copper refining tankhouses that started in 1987 (Schloen, 1987, 1991; Schloen & Davemport, 1995; Davenport et al., 1999; Robinson et al., 2003; Moats et al., 2007, 2013, 2016). In this installment, data collected from 2015 and 2018 will be presented and analyzed. The 2015 survey data were presented at Copper 2016 in Kobe, Japan. This survey will continue the analysis of previous data to illustrate long term trends in copper electrorefining, which were originally presented at the Davenport Symposium in October, 2014 (Moats, Robinson, & Wang, 2014). Refineries who supplied surveys are listed in Table 1. Cathode production data from 2015 and 2017/18 (from surveys presented in 2016 and 2019) are provided to indicate which plants provided surveys and when. This manuscript presents operating data for ~6.5 million tonnes of copper production, which represents 30–35% of the world’s copper electrorefining production. The detailed survey results are available upon request from the corresponding author.
