Key Highlights The iodine number (ASTM D4607) measures micropore adsorption capacity in mg/g and is the fastest field-usable quality test for activated carbon. BET surface area measures total internal surface in m2/g using nitrogen adsorption and provides a complete...

Key Highlights Coconut shell carbon is predominantly microporous with hardness numbers of 97 to 99+, making it the top choice for potable water and gold recovery applications. Coal-based carbon has a broader pore size distribution with significant mesopore content,...

Key Highlights CIL (Carbon-in-Leach) runs leaching and adsorption simultaneously; CIP (Carbon-in-Pulp) separates the two stages, completing leaching first before introducing carbon. CIL is preferred for preg-robbing ores where natural carbonaceous material in the ore...
