coal rank and analysis in mineral processing

CHAPTER 4 RESULTS AND DISCUSSION - COAL ANALYSIS

2016-10-31  Table 4.3: Inorganic oxide percentages (wt %) from normalised XRF analysis of whole-coal samples 4.2 Petrographic analysis of coals from different Highveld coal mines Petrographic analysis (Table 4.4) indicates that coals characterised in this study are inertinite-rich, with 64-77% inertinite and 19-30% vitrinite components on a mineral-free basis.

2019-10-7  Coal Analysis. Most, if not all, coals are tested prior to being used. Some markets require specific quality characteristics for the process in which the coal is used, and environmental regulations also require knowledge of a coal’s quality. Some products also require analysis of physical characteristics of coals for handling or processing.

Coalification - an overview ScienceDirect Topics

In the coalification process, the coal rank increases from lignite to anthracite, as shown in Figure 1.1. Coal rank is useful in the market, because it is a quick and convenient way to describe coal without a detailed analysis sheet. A more detailed description of coal rank is shown in Tables 1.2 and 1.3.
