Abstract
In this study, power ultrasound was used as aiding method for the
mineral processing technique, which have recently been developed for the
remediation of soil contaminated by heavy metal containing bullets,
their broken parts and alteration products. Power ultrasound was used to
disperse the soil to remove metals and metal compounds from soil
particle surfaces instead of attrition conditioning. The soil diluted
with water was treated using 22 kHz ultrasound power of 100 W up to 500
W. The effect of different ultrasonic treatment time and pulsation of
ultrasound were studied on the purity of sink and float fractions in
heavy medium separation process, screen fractions, and mineral
concentrates and tailings from flotation process. Ultrasound enhanced
the remediation of soil fractions in all the studied cases. Optimisation
of the ultrasonic power will be done in the continuation study.
