Carbon-in-Pulp (CIP) is one of the gold ore treatment processes and a type of cyanide gold extraction process. Its full name is the full mud cyanide carbon-in-pulp gold extraction process. It is a process in which the slurry after cyanide leaching of gold-containing ore uses activated carbon to adsorb gold-cyanide complexes.

Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. Heaps are typically ∼7 m …
