For treating refractory gold ore, what is the minimum sulphur/sulphide grade required for a BIOX circuit?

Thanks

It can be mentioned that the sulfide sulfur content of the material is a key factor in the design of the leaching system. If there is low-sulfur material, <1.0% sulfide sulfur, it is important to consider a heating system and/or to consider add more sulfur to the feed to operate at the right temperature. The site environment may have some influence. The temperature is important to maintain the bacteria in good conditions.  When there is a high sulphur content material, it will be necessary to evaluate the possible changes of temperature and how can affect the process, probably it could be necessary to install a system to control the temperature.
