The majority of the world's coal is mined from China, the United States, India, Australia and South Africa. According to the World Coal Association, more than 6,185 million tonnes (Mt) of hard coal was mined from coal mines around the world as of 2012. Coals mines use surface mining for coal deposits buried less than 200 feet underground.

Coal Preparation | SpringerLink · Abstract. Coal preparation, which may also be called washing, cleaning or processing, is the methodology by which coal feedstocks are upgraded in order to reduce freight costs, improve utilization properties and minimize environmental impacts.
METHODS OF COAL AND COAL ASH ANALYSIS INTRODUCTION: Analytical methods used in trace and toxic elements analysis of coal and its ash may be separated in to two categories. There are certain methods which can not be easily used for multi-element analysis on an individual sample. Certain trace elements are volatile.
The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, and the geology and environmental factors. Coal mining processes are differentiated by whether they operate on the surface or underground. Many coals extracted from both surface and underground mines require washing in a coal preparation ...
