— The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete cyanide and oxygen since this interferes with gold extraction kinetics.

 — Plant design for a gold ore should consider aspects of ore genesis, mineralogical characteristics and ore behaviour in each of the available metallurgical processes. Other factors include the selected mining method, impact of the project on the environment as well as economics.

 — Instead, the target of this study is to develop a software system that is able to give starting points for gold ore process design by helping the user to remember and compare previously successfully applied processing options on similar mining sites (Sauer et al., 2013, Sauer et al., 2014).

Gold minerals in this paper are defined as the minerals in which gold is present as a main constituent (e.g. native gold and electrum). Gold carriers are defined as both the gold mineral and the mineral in or on which gold occurs …

Determine the nature of visible gold including identification and location of all gold minerals, their size distributions, compositions, liberation characteristics, and associations with other minerals for predicting the grinding fineness and possible response of the ore to conventional gold recovery techniques.

Introduction. Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon-in-pulp circuit (CIP).

A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation

minerals present in gold ores is required to successfully design and operate a gold extraction process for optimum efficiency. We can fully characterize gold ores through comprehensive programmes including multi-stage diagnostic leaching, pre-concentration, process mineralogy and other complementary tests. When performed during the …

 — Gold-bearing mineral ores are divided into two categories based on their mineralogy and processing methods: free-milling, which includes quartz vein gold ore, oxidized ore, and silver, and ...

Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores.
