Limestone Deposits vs. Beneficiation
the chief aspects of beneficiation are "in plant" processes, such as crushing and screening, washing, grinding, flotation, and heavy-media separation. Numerous technical and eco-nomic problems exist. Detailed studies of the limestone deposit and the stone itself are required for intelligent beneficiation.

Coal beneficiation: theory and practice
Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash reduced when the −500 mesh material was removed.
