generally based on a compromise between reduced elution time and increased equipment costs at higher flow rates. Most columns are operated with upflow of solution, but some plants have selected to elute by downflow. The advantage to downflow is reduced potential for binding of flow distribution screens by tramp material in the carbon. Upflow operation means that the carbon bed is always ...

The Metallurgy of Cyanide Gold Leaching – An Introduction

Preg-robbing: Any microscopic carbon material in the ore will compete with the activated carbon to adsorb Au out of the cyanide solution, and prevent recovery (so called preg-robbing). Several other clay type minerals will have the same effect. Where preg-robbing material is present in the ore the process typically higher activated carbon inventories are used with more frequent stripping and ...

Adsorption / Active Carbon - Lenntech

Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated In this process active carbon is the solid. Activated carbon is produced specifically so as to achieve a very big internal surface (between 500 - 1500 m 2 /g).

Carbon-In-Column (CIC) Refractory ore processing methods almost always serve only one purpose, to treat ores that will not liberate their values by conventional cyanide leaching.

Gold CIL & CIP Gold Leaching Process Explained CCD

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.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.

Cyanide Leaching | Mining | SGS

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns).

Carbon columns consist of large columns (5 to 8 ft diameter) and 15 to 20 feet in height, charged with activated carbon. The minimum load of carbon rule of thumb is one pound of activated carbon per 0.1 ounce of gold present in the solution. Usually, it is several pounds per 1/10 ounce, though, as the cost of carbon is relatively insignificant compared to timely recovery of gold.
