Yttrium associations in coal ashes prior to and after their leaching in HCl

What is it about?

Paper elucidates yttrium concentrations in particle size fractions of coal ashes (bottom ash and fly ash from 3 sections of ESP). Modes of occurrence of yttrium in these ashes were discussed in relation to their leachability in cold dilute HCl.

Why is it important?

As economically mineable deposits of yttrium are scarce, there is a growing need to expand the production to some new sources, optimally some waste materials, whose vast amount is produced annualy throughout the world (e.g., coal combustion ashes).
