Choosing activated carbon for gold recovery in the Philippines is not simply a matter of selecting the highest activity number. Carbon performance is shaped by the ore and solution chemistry, the adsorption process, residence time, carbon inventory, screen condition, elution and regeneration practice, and the physical durability of the granules. A useful buying process therefore combines technical specifications with plant data and a controlled qualification trial.
What activated carbon does in a gold-recovery circuit
After gold is dissolved into a cyanide solution, activated carbon provides a very large internal surface where the dissolved gold-cyanide complex can adsorb. Loaded carbon is separated from the process stream, washed, eluted, and returned to service after regeneration. The carbon must adsorb effectively while surviving repeated mixing, pumping, screening, transfer, acid washing, elution, heating, quenching, and reuse.
In Philippine gold operations, activated carbon may be used in carbon-in-pulp (CIP), carbon-in-leach (CIL), or carbon-in-column (CIC) systems. Each process contacts carbon differently, but all rely on a combination of adsorption activity, granule strength, controlled sizing, and good operating discipline.
Specifications buyers should compare
Activity and iodine number
CTC activity and iodine number are useful indicators of pore development, but neither test reproduces every plant condition. They should be read with actual loading data, kinetic testing, solution chemistry, and the condition of fresh and regenerated carbon.
Hardness and attrition resistance
Hard carbon helps limit the generation of fines during handling and regeneration. Fines can be difficult to retain on screens and may carry adsorbed gold out of the recovery circuit. A high laboratory hardness value is useful, but handling practice and kiln operation also affect real carbon losses.
Ash, moisture, and apparent density
Ash reflects non-carbon mineral content, moisture affects received weight and handling, and apparent density influences inventory calculations and volumetric behavior. These values help purchasing and process teams compare deliveries on a consistent basis.
Particle-size distribution
Mesh size influences screen retention, hydraulic behavior, carbon transfer, and adsorption kinetics. CocoCARB gold-recovery grades list a confirmed 6 x 12 mesh specification. A request for 6 x 16 mesh should be confirmed as a separate requirement before quotation.
How CIP, CIL, and CIC requirements differ
In CIP, leaching is substantially completed before adsorption, so carbon moves through a separate adsorption train. In CIL, leaching and adsorption occur in the same tanks, placing carbon in continuous contact with slurry during dissolution. CIC generally treats clarified solution in columns. The carbon concentration, contact method, solids exposure, screen arrangement, transfer frequency, and regeneration schedule vary among these configurations.
Buyers should describe the actual process when requesting a sample. A statement such as “gold recovery use” is a starting point, but circuit configuration, existing grade, make-up rate, target loading, and observed losses provide much stronger context.
Selecting between CTC 50, CTC 55, and CTC 60
CocoCARB offers CTC 50, CTC 55, and CTC 60 activated carbon grades. The increasing CTC number indicates increasing activity under the referenced test, but a higher number does not automatically deliver the lowest total operating cost. A plant should compare loading rate, equilibrium capacity, attrition, regeneration response, inventory, losses, and commercial value under representative conditions.
CTC 50 may suit operations seeking dependable standard performance. CTC 55 offers an intermediate activity level, while CTC 60 is intended for more demanding duties. The correct choice is the grade that performs reliably in the customer’s circuit, not the grade with the largest number in isolation.
Plan a responsible qualification trial
Begin with a review of current specifications, recent carbon analyses, plant recovery, carbon losses, screen performance, and regeneration conditions. Laboratory adsorption and attrition testing can narrow the options. A controlled plant trial should then use agreed sampling points, baseline data, sufficient duration, and clear acceptance criteria.
During the trial, track carbon addition, inventory, loading, barren solution, fines, screen oversize and undersize, transfer behavior, elution results, and regenerated-carbon activity. Avoid changing several major operating variables at the same time, because doing so makes the effect of the carbon difficult to isolate.
Documentation and Philippine supply planning
A gold recovery activated carbon supplier in the Philippines should be able to discuss the product grade, mesh specification, packaging, sample availability, typical technical data, safety information, batch documentation, quantity, destination, and target schedule. CocoCARB is available in 25 kg sacks and 550 kg bulk bags, subject to quotation and confirmation.
Include the mine location, delivery point, required volume, consumption forecast, desired documents, and whether the inquiry is for a laboratory sample, plant trial, or routine supply. This allows Richson’s Trading to prepare a response that addresses both technical and commercial needs.
Key takeaway
The best activated carbon for gold mining in the Philippines is the product that combines appropriate adsorption performance, high durability, controlled particle sizing, clear documentation, and dependable supply for the specific circuit.
