Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80% even after fine grinding. 1) Arsenic-bearing refractory gold ore has stones extremely difficult to deal with. In the stones, gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice.

REFRACTORY ORE PROCESSING. The common definition of "refractory" gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
Also, grinding the ore to an extremely fine particle size can liberate gold encapulsated in sulfides. SGS has very extensive experience with all the unit operations involved in the processing of refractory gold ores, and in selecting the optimum flowsheet for a particular ore. Our gold metallurgy expertise is second to none. Chemical interference
For the processing of free-milling ores to refractory gold ores, Outotec offers end-to-end process solutions including comminution, flotation, pressure oxidation, bio-oxidation (BIOX ...
For the recovery of gold from refractory ores and concentrates, roasting has been used extensively for decades. For severe refractory gold ores, it was the exclusive pretreatment process and, accordingly, its development is presented in detail in this chapter, finishing with the most recent technology: oxygenated roasting for whole ores.

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
Refractory Gold Processes Mineral Processing. 2020-7-22 Gold can be leached and extracted/recovered in several ways. Even if you gold is "refractory" in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost.
In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process. ... Gold:sulphur ratio (GSR) Refractory ores are typically treated by flotation ...
Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
