HAYCARB ACTIVATED CARBONMulti-Tech Services is pleased to announce we are now representatives of HAYCARB PLC, introducing the HAYCARB Activated Carbon.

Haycarb offers the gold adsorption test facilities and expertise in Gold activity, loading capacity, Rate of adsorption, Soft particle % and platelet % measuring tests, hardness measuring tests, testing and analysis of spent carbon, expertise of our in house metal lurgist. 


It’s a carbonaceous, highly porous adsorptive medium that has a complex structure composed primarily of carbon atoms. The Activated carbons are manufactured from coconut shell, peat, hard and soft wood, lignite coal, bituminous coal, olive pits and various carbonaceous specialty materials. Chemical activation or High Temperature Steam Activation mechanisms are used in the production of activated carbons from these raw materials.


Activated carbon is mainly available in three forms or shapes: powder, granular and extruded and each form is available in many sizes. Based upon the application and requirements, a specific form and size are recommended.

  • Granular Activated Carbon (GAC) - GAC are irregular shaped particles formed by milling and sieving, ranging from the sizes 0.2mm to 5 mm. They have the advantages of being harder and longer lasting than powdered activated carbons, clean to handle, purify large volumes of gas or liquids of a consistent quality and can be reactivated and reused many times. GAC are used in both liquid and gas phase applications and in both fixed and moving systems. The Granular activated carbons are nearly always regenerated and reused, the period between reactivation varies significantly but is on average 18 months. Loss of material during reactivation ranges from 5% to 15%.
  • Powdered Activated Carbon (PAC) - PACs generally have a particle size distribution ranging from 5 to 150 Å although there are coarser and finer grades available. Advantages of powdered activated carbons are their lower processing costs and their flexibility in operation. The dosage of powdered activated carbon can be easily increased or decreased as process conditions vary. Powdered activated carbons are mainly used for liquid-phase adsorption. 
  • Extruded carbon - These are cylindrical pellets with diameter ranging from 1mm to 5mm. The extrusion process together with the raw material used, ensures that the end product is hard and suitable for heavy duty applications. The extruded pellet form gives a low system pressure drop, which is an important consideration in the gas-phase uses. Markets lie in solvent recovery, gas purification and automotive emission control, where the high volume activity, low pressure drop and high stock resistance of extruded carbon enable them to last the entire life of the vehicle.


Our high density carbons with particle to particle consistency in activity and shape is an ideal solution for applications in CIL (carbon-in-leach), CIP (Carbon-in-pulp) and CIC (carbon-in-column) processes in gold mining. Our activated carbons have superior adsorption kinetics with very high gold adsorption rates and capacities
