The initial results for the cyanide leach gold recoveries were very poor on a high-grade primary sulphide ore of 6.2 g/t Au with no silver. Subsequent mineralogy showed the ore to be a characteristic pyrite, carbonaceous refractory gold ore (double refractory). This was a very disappointing finding. A small scale gravity and flotation test programme was developed to …

A gold mine has an elevator that travels approximately 4000 ft down a deep shaft. The shaft is a vertical excavation adjacent to the mine's gold ore body. Shaft haulage is more economical than truck haulage at this depth. The ore from the mine is dumped down an ore pass (a vertical excavation), where it falls to a collection level.
