Pulling more mass has complicated process and mechanical implications as larger mass often cannot be handled by pumps or flotation cells for lack of volumes. For base metals plants/concentrators, a stage process that yields more than 20% mass pull, is likely to fails. It does not concentrate enough.

Roughly 95% of the current lubricant market is dominated by conventional (mineral-based) oils. While many are aware that these mineral oils originate from crude stocks, the intricacies of the refining process remain relatively unknown. Mineral base oils, also known as conventional oils, form the backbone of the majority of lubricants used today.
