Advantages:

Our product uses 100% coconut shell. It has a very high hardness and is more wear-resistant than any other type of activated carbon. Our gold recovery carbon delivers exceptional loading rates with superior kinetics in high-pulp density applications. The optimized pore structure creates ideal gold cyanide complex adsorption while resisting organic fouling. With its industry-leading hardness rating, it maintains size integrity through multiple elution cycles. Mining engineers appreciate its consistent screen sizing that prevents carbon migration through interstage screens. The low ash formulation ensures minimal interference with downstream electrowinning. Users consistently report gold recoveries exceeding 99% in challenging ore bodies. The controlled activation process creates carbon with precisely engineered mesopore/micropore ratio optimized for rapid gold loading while maintaining excellent physical durability under aggressive agitation conditions.

Application:

High-throughput mining operations rely on our carbon for processing low-grade ores economically. Refractory ore processors use it to maximize recovery from complex mineralogy containing preg-robbing components. Artisanal mining cooperatives depend on our carbon for achieving professional-grade recoveries with simplified equipment. Precious metal refiners incorporate it into their circuits for recovering values from process solutions. E-waste recyclers choose our carbon for selectively extracting gold from complex leach solutions. Tailings reprocessing operations utilize it for recovering previously unrecovered values. From conventional CIP/CIL circuits to innovative heap leach applications, our coconut shell gold recovery carbon effectively captures gold-cyanide complexes even in the presence of competing ions—delivering exceptional performance in applications where metallurgical efficiency directly impacts profitability. Its reliable performance under varying pulp densities, pH conditions, and competing ion concentrations makes it the preferred choice for operations seeking to maximize recovery while minimizing carbon inventory costs through extended cycle life and reduced attrition losses.

Carbon-in-Pulp (CIP) Process: Efficient Gold Adsorption from Leached Slurry

The Carbon-in-Pulp (CIP) process is a widely used method for gold recovery following cyanide leaching. The process begins with ore that is finely ground and then subjected to gold dissolution in a series of agitated cyanide leach tanks. Once leaching is complete, the resulting slurry, containing the dissolved gold, is transferred to a dedicated CIP adsorption circuit.

This circuit typically consists of a cascade of five or six agitated tanks. Granular activated carbon is introduced into this series of tanks, where it moves counter-currently to the flow of the leached slurry. This staged, counter-current contact is a key feature of the CIP process, ensuring that the freshest carbon meets the solution with the lowest gold concentration, thereby maximizing the efficiency of gold adsorption. As the carbon adsorbs the gold from the slurry solution, it becomes progressively loaded with gold. The gold-laden carbon is then mechanically separated from the barren slurry through coarse screening, ready for the gold elution (stripping) stage. This highly efficient system achieves high gold recovery rates by optimizing the concentration gradient between the carbon and the solution.

Carbon-in-Leach (CIL) Process: A Combined Leaching and Adsorption Method

The Carbon-in-Leach (CIL) process is an efficient gold extraction method that integrates leaching and adsorption into a single operational step. Instead of using separate tanks, the leaching tanks are equipped with carbon retention screens, eliminating the need for a dedicated carbon-in-pulp (CIP) circuit. In this process, activated carbon is introduced directly into the leach tanks, allowing for the nearly simultaneous dissolution of gold by cyanide and its immediate adsorption onto the carbon.

This method is particularly advantageous for processing gold ores containing native carbon (often present as organic matter). The native carbon can prematurely adsorb the dissolved gold (a phenomenon known as “preg-robbing”), leading to significant gold losses and lower recovery rates. In the CIL process, the added activated carbon acts as a preferential adsorbent, effectively competing with the native carbon to capture the gold. This ensures that the gold is successfully loaded onto the activated carbon, from which it can later be recovered through a stripping process.
