Shock Potential Mitigation at a Copper Electrolytic Electrowinning Plant

Abstract

Following an electrocution of a non-electrical worker at another Arizona copper mine in April of 2016 The Safety, Electrical and Solvent Extraction Operation departments of our mine, with the assistance of the local MSHA (Mine Safety & Health Administration) office identified similar DC shock hazards at our facility. This case study will outline those hazards found due to stray current traveling through electrolyte piping and the mitigation and training solutions implemented.
