Blending Coal - an overview | ScienceDirect Topics
C.S.B. Nair, in Analytical Methods for Coal and Coal Products, Volume II, 1978 I Briquetting, Core Binders, and Target Pitch. Coal briquets are made of blending coal fines with 8–10% of powdered medium-soft pitch at ∼90°C. The soft mass so obtained is shaped into rectangular briquets in a ram press or formed into ovoids in a continuous roll press.

How are the blended colors computed in this case?
This is the result in a graphics editor (GIMP): The resulting color is (0, 0.93, 0, 0.59). If we blend these colors with color blend formula C1 * (1 - A2) + C2 * A2 and calculate alpha A1 * (1 - A2) + A2 we get (0, 0.5, 0, 0.59). Alpha is correct, colors are not. Output color is grayish green. That becomes very noticeable on white background.

Many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. For example, Jo (1965) considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component (coal rank) and the addition of a suitable amount of caking …

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.
