Scanning electron microscopy confirmed fine particles of metallic gold in all size fractions, but were most prevalent in the sub 45 micron size fraction (see Figure 2). Composition of the gold particles was found to vary. Table III

ACTIVATED CARBON IN GOLD RECOVERY Kemix
2018-1-15 This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as

GOLD ADSORPTION ON ACTIVATED CARBON AND
2010-11-5 The adsorption of gold cyanide from clear solutions was found to be characterized by intra-particle diffusion rate control, limited by a finite film mass transfer rate at low gold loadings. When fine suspended solids are present it is shown that blinding of the carbon macropores is the likely cause of the reduced adsorption rate.

The Metallurgy of Cyanide Gold Leaching An
2014-10-20 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.
