The Extractive Metallurgy of Gold SpringerLink

The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the Abstract. Problem ores that yield low (say less than 80%) gold recovery by cyanidation when “normally ground” are defined as refractory. The term, as well as the technical methods used to treat such ores, are relatively new. Rose and Newman’s very comprehensive book, The Metallurgy of Gold, does not even contain the term refractory in itsTreatment of Refractory Gold Ores SpringerLink

Over 50% of the gold mines in South Africa employ gravity concentration ahead of the cyanidation circuit. Some of the South African mills also recover, by gravity, fine particles of osmiridium that occur in the gold reefs. Many devices are used for gravity concentration of the cyclone under­flow (Figures 4-8 and 4-9).in extractive metallurgy are: native gold, electrum and tellurides. Gold is often hosted in sulphide minerals like pyrite and arsenopyrite and in compounds of the elements selenium and antimony [1]. Native gold is the main form of gold occurring in nature, with a gold content of 90% or more and frequently accompanied by silver. In com-The extractive metallurgy of gold Springer

The extractive metallurgy of south africa’s platinum ores

The extraction technology for platinum-group metals (PGMs) has changed dramatically in the last 80 years, and the changes are likely to continue for years to come. This article will review advances in PGM extraction, including developments in semi-autogenous and fully autogenous milling; flotation equipment applications for treating high-chrome ores; The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained The process mineralogy of gold: The classification of ore types

Challenges and opportunities in the recovery/rejection of

The process does not usually result in optimum recovery of gold due to the difference in mineralogy, morphology and surface chemistry between copper minerals and gold-bearing particles (Agorhom et al., 2012a). Consequently, gold recovery in copper ores always lags copper recovery by 10–15% (Bulatovic, 1997, Small et al., 2003) as shown Volume 2: Extractive Metallurgy of Gold Edited by C.E. Fivaz and R.P.

Characterization of Goldstrike ore carbonaceous material

Carbonaceous material (CM) from the Barrick Goldstrike Mines, NV, was characterized with respect to its gold sorption (preg-robbing) and gold recovery behavior. The breadth of graphite peaks measured by X-ray diffraction were used to calculate crystallite dimensions (002) of the CM. The (002) dimension was found to vary inversely M6 Assay and Analytical Practice in the South African Mining Industry (1986) W.C. Lenahan and R. de L.
