Particle characterization of activated carbon often includes size, shape, and surface area measurements. Dynamic image analysis has proven useful for the size and shape analysis of many forms and grades of activated carbon and has successfully replaced older techniques such as sieving at factory plants around the world.
Typical Applications Agriculturals Minerals Flame Retardants Catalysts Cosmetics TYPICAL JET-O-MIZER PARTICLE SIZE DISTRIBUTION MICRO-JET™ HORIZONTAL JET MILLING / PROCESSING Capable of ultra-fine grinding dry powders to 0.5-45-micron averages, our Micro-Jet horizontally oriented jet mill generates a maximum amount of "fines," for customers .
However, in the case of using activated carbon for adsorption of minerals such as gold, the particle size should be in the range of 3.35–1.4 millimetres (0.132–0.055 in). Activated carbon with particle size less than 1 mm would not be suitable for elution (the stripping of mineral from an activated carbon).
Here is a chart of particle size that I found on Wikipedia. It’s a good starting point for discussion as we all know what happens when an allergic person comes into contact with pollen or cat dander. The grade of activated charcoal I use is from Coconuts and it has a mean particle size of 15 microns.
Particle Size . Particle size has a direct effect on adsorption kinetics, flow characteristics, and filterability of the activated carbon.¹. Activated Carbon Production. Activated carbon is produced through two main processes: carbonization and activation. Carbonization
