An experimental evaluation of the leaching kinetics of PGM-containing Ni–Cu–Fe–S Peirce Smith converter matte, under atmospheric leach conditions by van Schalkwyk, R., Eksteen, Jacques, Petersen, J., Thyse, E., Akdogan, G.

“…In a first stage atmospheric leach in a typical Sherritt Ni–Cu matte leach process, a Ni–Cu–Fe–S Peirce Smith converter matte is contacted with recycled copper spent electrolyte (an aqueous copper sulphate/sulphuric acid solution) at 85 °C with the purpose of dissolving nickel, while simultaneously removing copper from solution. …”

Solid-liquid mass transfer in a Peirce-Smith converter: A physical modelling study by Chibwe, D., Akdogan, G., Eksteen, Jacques

“…Pyro-metallurgical processes are multiphase in nature involving gas-liquid-solid interactions. In the Peirce-Smith converter operation, the additions of cold solids in liquid matte in the form of fluxing agents (silica sands) for slag liquidity, process scrap and reverts for temperature control is a common practice. …”

Towards sonic injection in Peirce-Smith converters: A computational fluid dynamics (CFD) Modelling Study by Chibwe, D., Akdogan, G., Bradshaw, S., Bezuidenhoudt, G., Davis, J., Eksteen, Jacques, Kapusta, J.

“…This research work forms part of an assessment to complement the feasibility of implementing high pressure sonic injection into relatively small (2.25 m I.D by 3.66 m I.L) Peirce-Smith converters (PSC) used at Lonmin Plc. Work has been carried out to characterize the fluid dynamics of three-phase (air, matte and slag) fluid flow in these converters using Computational Fluid Dynamics (CFD) simulations. …”
