The BIOX Process for Biooxidation of Gold-Bearing Ores
Abstract. GENCOR S.A. Ltd. has pioneered the commercialization of biooxidation of refractory gold ores. Development of the BIOX process started in the late 197os at GENCOR Process Research, in Johannesburg, South Africa. The early work was championed by Eric Livesey-Goldblatt, the manager of GENCOR Process Research

Sulphidic refractory gold ore pre-treatment by selective ...
In sulphidic refractory gold ores, fine gold particles may be highly disseminated and locked up in sulphide minerals such as pyrite and arsenopyrite. Hence, pre-treating processes are necessary to extract gold for further processing methods like cyanidation. In this paper, the selective and bulk ...

Refractory materials. Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they must be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion.
Treatment of carbonaceous refractory gold ores
Gold ores can be categorized into two types free milling and refractory. Free milling ores are those easy to process by simple gravity techniques or direct cyanidation.
