Coal deposits have attracted much attention in recent years as promising alternative raw
sources for rare earth elements and yttrium (REY), not only because the REY concentrations …

The material classed as “mineral matter” in coal embraces crystalline mineral materials as
well as a range of inorganic elements that occur in non-crystalline form. This review outlines …

Currently, there is an increasing industrial demand for rare earth elements (REE) as these
elements are now integral to the manufacture of many carbon-neutral technologies. The …

Many studies have been published in recent years focusing on the recovery of rare earth
elements (REEs) from coal-related materials, including coal, coal refuse, coal mine …

This paper presents data on widespread abnormal accumulations of lanthanides and yttrium
