<h3>CarboninPulp  ScienceDirect</h3><p>The rate of carbon attrition is typically a function of carbon inventory, elution rate (i.e., gold loading), and carbon handling during transfer, elution, and regeneration. High carbon inventories result in extended carbon residence, with the carbon being subjected to increased attrition time in the tanks. </p>
