Question 1 (18 points) a) Compare and contrast the properties of "activated carbon" and a "strong base resin" for adsorbing gold from typical cyanide process liquors. b) Describe their structure/functional groups and the mechanism by which gold is loaded. Summarize the advantages/disadvantages of resins. c) Draw a flowsheet of a typical carbon-in-pulp process which treats gold, consisting of 4 leaching and 6 adsorption stages, including the associated comminution, elution, regeneration and electrowinning sections of the full circuit, and briefly describe the operation.
