The process design of gold leaching and carboninpulp
Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening Leaching takes place in a series of agitated leach reactors or pachucas Before leaching the pH of the pulp is normally adjusted to a value of around 95–11 to ensure minimum loss of cyanide as hydrogen cyanide 2013) These cyanide consumption values can dramatically increase the operational costs in a cyanidation plant 2 Increasing the cyanide concentration in the leach tails: Cyanidation plants include recycle streams to recover water and cyanide Nevertheless, these Designing the SART process – A review plant The leach circuit comprises 22 tanks with a total volume of 44 000 m3 in two parallel streams that allows for a total retention time of 7 hours Calcium cyanide is added at an addition rate of approximately 350 g/t Due to the large tonnage multiplier, this equates to approximately 1 000 (as 100% NaCN) tons of cyanideCyanide control in the metallurgical process of gold Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon CIL stands for carboninleachGold CIL CIP Gold Leaching Process Explained CCD Comsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant Although the heap leach took several months to achieve the same recovery, the economics favored the heapPrecious Metal Heap Leach Design and Practice
