ABSTRACT:
A method for harvesting weighting agent fines includes milling weighting agent into a plurality of pieces, classifying the pieces based on size to extract those particles having a particle size less than an acceptable maximum diameter, reclassifying the pieces based on size to extract those particles having a particle size less than an acceptable minimum diameter, collecting the particles having a particle size between the standard acceptable minimum and maximum diameters, and collecting the particles having a particle size less than the acceptable minimum diameter. A system for harvesting weighting agent fines includes a mill to reduce the weighting agent particle size, a first classifier to extract particles having a particle size less than the acceptable maximum diameter, a second classifier to extract particles having a particle size less than the acceptable minimum diameter, a fine particle collection area, and a coarse particle collection area.
