~57Fe Mossbauer Effect Spectroscopy Monitoring of Iron-Bearing Products from Beach Sand Minerals Processing

摘要

Beach sand minerals from the volcanic rock structures of the Drakensberg, Kwazulu-Natal, (Sough Africa) were been processed. Screening, flotation, spiral concentration and magnetic separation methods were used either separately or successively in an attempt to concentrate monazite minerals. Products thereof and those froma long time (up to 72 hours) microwaves treatment of the finally produced ilmenite-bearing minerals have been studied using the Mossbauer effect spectroscopy. The ~57Fe Mossbauer effect spectroscopy has demonstrated its versatility and power in monitoring the ilmenite internal reduction mechanism and products and, in characterising the iron-bearing phases contained in different products from the beach sand minerals processing.
