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.
