350 TPA SX-EW Copper Cathode Plant from Copper Ash
Commercial Challenge & Objectives
Core Process Engineering Scope
Proventus Valuetech isolated and engineered the high-value metallurgical core of this facility:
Selective Leaching & Mass Balance
Engineering the chemical agitation and leaching circuits to maximize the dissolution of copper from the ash matrix while minimizing iron and impurity carryover.
Solvent Extraction (SX) Circuit Optimization
Design and configuration of the mixer-settler arrangement, selecting optimal organic extractants and scrubbing loops to enrich the aqueous electrolyte stream.
Electrowinning (EW) Cell House Configuration
Custom layout of the electrowinning cell parameters, including precise busbar sizing and current density regulation to guarantee dense, non-porous cathode deposition.
Project Delivery Mode Execution
Owner's Engineering Consultant (OEC)
Acting as the Owner's Engineering Consultant (OEC), Proventus Valuetech served as the investor's independent technical authority. We performed critical drawing reviews of the hydrometallurgical equipment layout, audited the fabrication tolerances of the specialized plastic/composite mixer-settlers, and supervised the sequential fluid-loop commissioning protocols to ensure contract compliance and safe chemical handling.
