various minerals and also their distribution in different size fractions. It indicated that manganese and hematite are valuable mineral present, whereas Pb and Zn are the trace element compositions and the gangue mineral that present in the ore is silica. Based on the assay value of each size fraction
Garnierites (Ni–Mg-bearing phyllosilicates) are significant ore minerals in Ni-laterites of the hydrous silicate-type. In the Falcondo Ni-laterite deposit (Dominican Republic), garnierites are found within the saprolite horizon mainly as fracture-fillings and thin coatings on joints. Field observations indicate an important role of active brittle …
The microstructure and mineral composition of the gangue play a decisive role in the precipitation of heavy metal elements. In this study, the microstructure, …
Mechanical flotation of gangue minerals is reviewed. First, mechanisms that contribute to gangue transportation are considered. The effect of water recovery and other essential factors on gangue recovery is described, and mathematical models for classification and entrainment of gangue are presented. The importance of froth …
