Dual energy ?-ray transmission techniques have
considerable potential for on-line analysts in the
mineral and coal industries. Calculations have shown
the benefit of careful choice of the two 7-ray energies
m relation to the specific application Promising
applications include determination of lead m ores and
ore products, iron m high grade iron ore, uranium in
solutions and ash m coal The possibility of determination of sulfur content of coal indirectly via iron
from combination of dual energy "/-ray transmission
and pair production techniques has been discussed
Far more experimental work must be undertaken to
evaluate this possibility
