Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.
of subsequent physical coal demineralization can be improved by chemical pretreatment, especially for physical processes which exploit surface chemistry. Examples describing the advantages of chemical processing prior to physical coal beneficiation are included in this talk. INTRODUCTION

Liquefaction: Any process by which solid coal is converted to a liquid fuel. Oxide: ... These are deposited initially as peat, but burial and increase in temperatures at depth bring about physical and chemical changes. The process of 'coalification' results in the production of coals of different ranks ('coal …
Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.4 billion tonnes in 2010. Around 721 million tonnes of coking coal was used in the production of steel.

Coal processing is where raw coal from the mine is cleared using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market or can be used for different purposes such as power generation.
This article considers the geological origins, structure, and properties of coal, its usage throughout human history, and current world distribution. For a discussion of the coal-extraction process, see the article coal mining. For a more complete treatment of the processes involved in coal combustion, see the article coal utilization.
With coal preparation, raw coal is cleaned using different physical processes, with or without any chemical reagents, to get a product which can be sold in the market. Coal preparation process starts with crushing and screening of freshly mined coal, which removes some of the non-coal material.
