Differences Between CIL and CIP Gold Extraction
CIP: CIP requires separate leaching and adsorption tanks. Although there are more tanks, each tank is simpler in design and offers greater operational flexibility. 2.3 Gold Ore Characteristics. Ore Type Suitability: CIL is more suitable for low-grade, high-clay-content ores as these ores can clog the leaching tanks during processing.

Gold Leaching Agitation Tanks
For gold ores agitation periods vary from 16 to 48 hr., probably averaging 30 hr., and for silver ores nearly twice this period. Dilution during agitation varies from 1 of solution to 1 of solids by weight to 3 of solution to 1 of solids, occasionally higher, probably averaging 2 to 1.
Application Note Cyanide Leach Process
Cyanide Leach Process - pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level (>10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore.
