Abstract

Language:

Alkaline sulfide leaching technology (i.e. ASL) has been studied, presented and published throughout the literature and utilized in some current engineering studies. Yet, the actual industrial applications are very few and the knowledge about these is very limited. Hence, a large gap between the laboratory, publications, engineering studies, and the actual industrial plant exists. Recent studies of ASL applied to copper enargite concentrates definitively bear out this dichotomy. Hence, this paper will seek to dispel the common misperceptions that continue to surround the selective industrial ASL hydrometallurgical technology. For edification of the reader, a listing of ten common misconceptions and myths is listed. As well, ASL history, fundamental aspects and a new flowsheet application for simultaneous gold and high purity antimony oxide production from low grade materials is included. The associated estimated economic considerations are also included to heighten enlightenment about the application of this industrially proven technology.
