Gold mining is one of Western Australia's largest mineral industries, with an annual production of over 192 tonnes worth around billion. Almost all mines use a cyanide leaching process to extract the gold from the ore. In this process the finely milled ore is mixed with a sodium cyanide solution that dissolves the gold.
The Society of Mining Engineers Uganda (SMEU) is a competent entrant into the mining sector in Uganda. The organisation comes with proficient technology and human resources to enhance mining as a key engine in industrial and economic development.

initial leachsolution. Keywords: Gold, Cyanide, Leaching, Bottle Roll Test, Pregrobbing, Cyanicide 1. Introduction Cyanide leaching of gold is a very common methodology for evaluation of low grade gold ores. Despite risks associated with cyanide, the method proved to be highly effective provided that necessary precautions are taken.
