Coal blending - Wikipedia
Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal's intended application (e.g. steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.

Definition of ore blending glossary
Definition of ore blending. Method whereby a mine, or a group of mines, served by a common mill, sends ores of slightly varied character for treatment and separate bins or stockpiles are provided. From these, regulated percentages of ores are drawn and blended to provide a steady and predictable feed to the mineral dressing plant.
