Coal preparation performance testing : ALS

ALS facilities offer sampling services that include comprehensive plant audits, metallurgical investigations, and routine quality control. Using unique pilot-scale coal preparation plants, ALS can prepare a simulated product for the generation of marketing samples and/or feed material for pilot scale coking and combustion studies.

ASTM Coal Sampling Standards

"D 2234 [D 2234/D 2234M, Standard Practice for Collection of a Gross Sample of Coal] is the basic sampling standard that we have, but it covers mechanical and manual sampling. The group wants to produce a stand-alone mechanical sampling standard," says Strang, a coal-preparation consultant, Big Stone Gap, Va.

Laboratory Methods of Sample Preparation

Sample preparation method and Laboratory sampling procedures involve either: Coning and Quartering; or Riffling Method. Coning and Quartering for sample preparation techniques/method The method which is used for sampling large quantities of material say 20kg, consists of pouring or forming the material into a conical heap upon a solid surface (e.g. a steel plate) and relying on radial symmetry ...


All coal analyses should follow standard procedures in order to obtain repeatable and reproducible results. This course reviews the various aspects of coal sampling and analysis. It provides descriptions of standard procedures for coal sampling, preparation and routine testing of coal specified in the international Standards.

USGS Bulletin 1823 - Preparation of Coal for Analysis

The normal preparation procedure requires that each air-dried coal sample pass through a jaw crusher; one subsample (split) of the crushed material (2 to 4 mm, or 5 to 10 mesh) is then taken for the ultimate and proximate analyses, and another split is reduced to approximately 150 m m (100 mesh) by a vertical grinder for chemical analysis.


Sample identification numbers are permanently etched into the bottles. Samples were stored in the manner indicated in Figure 2. The coal was then riffled into 3-kg representative splits. Preparation of a 16 x 100 Mesh Analytical Sample One of the 3-kg samples of the -4 mesh coal (the "working sample") was stage-
