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. If use conventional

2020-8-18 Refractory gold ore refers to the part of gold ore that cannot be extracted effectively by the conventional cyanide leaching process after the fine grinding. The gold in this type of gold ore cannot contact with the cyanide solution due to physical encapsulation or chemical combination, resulting in a very low gold leaching rate.

2017-7-10 Table 1 shows the chemical analysis of Sarigunay refractory oxide gold ore. The gold content of the ore was determined as 2.8 ppm by fire assay method. The XRD pattern of the ore is seen in Fig. 1. As it is seen, the gold ore has an oxide nature and quartz, epidote, muscovite and orthoclase are major minerals in the ore.
