Column Leach Test Procedure & Variables

16/10/2017 Leach column 7 was irrigate with 0.003 lps/m², leach column 8 with 0.006 lps/m², and 0.004 lps/m² was used in leach column 9. The results show that does not matter what flowrate is used the total recovery will be the same for all cases, but the acid consumption and time will not be the same.

The Metallurgy of Cyanide Gold Leaching An Introduction

20/10/2014 Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold. Cyanidation is used for gold that is distributed
