Gold recovery is particularly interesting because of its wide range of industrial applications and high market prices. The aim of this investigation is to establish the presence of Au and other useful components in mining wastes in Bulgaria, to evaluate their content quantitatively as well as their distribution in different technological products of the flotation process. The study includes SEM analysis to characterize the different minerals twins, micro inclusions of gold and other useful components, their belonging to different minerals or free state, their shape, size and phase inhomogeneity.enArticle
