Apr 11 2021 Colombia has a long and rich history of gold mining dating back to the pre Colonial era (Brooks et al 2016) Gold mining is an important economic driver in the impoverished rural regions in Colombia with around 300 000 miners working in the artisanal and small scale gold mining (ASGM) sector on a mainly subsistence basis producing an estimated 54 metric tonnes (Mt) of gold annually.A leaching model for gold ore that takes into account the impact of cyanide and oxygen concentrations as well as gold surface exposure on leaching performance is developed Cyanide consumption is estimated by an empirical model that is a function of ore particles size distribution as well as cyanide copper and sulphur concentrations.
