摘要:Abstract(#br)Selective separation of pyrite from base minerals is very important and challenging. This research investigates the combined inhibitory effect of two novel reagents on flotation behaviors of pyrite and galena under the low alkaline conditions. The depression and adso...

摘要:Abstract(#br)Mixed copper ores are challenging to process, where the treatments are expensive, resulting in low recoveries, with products that are not commercially viable. The proposed research aims a sustainable method to recover copper from a mixture of oxides and sulfides mine...

摘要:Abstract(#br)The size-energy relationships in comminution are useful models that relate the energy requirements of a process to the changes in size of the particles. In the generalized theory, the energy is a function of powers of the initial and of the final size. Because of the...

摘要:Abstract(#br)In the mineral processing industries, the performance of hydrocyclones used in solids classification tasks influences the efficiency of downstream processing. Typical operation involves a fan shaped underflow profile, while undesirable roping and underflow blockage c...

摘要:Abstract(#br)Induction time, an important factor in the adhesion process of mineral particles to bubble surfaces, has been determined only by experimental methods that are time consuming and expensive. This study aims to introduce a numerical approach to describe bubble–plat...

摘要:Abstract(#br)The authors have developed a process for the direct production of the rare earth elements oxides (REO) through the calcination of a raw ore that contains carbonate minerals, such as bastnaesite (a known REE bearing carbonatite) and gangues (e.g., calcite, dolomi...

摘要:Abstract(#br)In this paper, digestion behavior and removal of sulfur in high-sulfur bauxite during Bayer process were studied. The thermodynamic analysis shows that pyrite reacts with alkali solution to generate different valence sulfur (S 2− , S 2 O 3 2− , SO 3 2− , SO...

摘要:Abstract(#br)Two approaches for the use of the Electric Pulse Fragmentation (EPF) in the beneficiation of a low-grade cassiterite schist ore were investigated through pilot-scale tests performed on samples of about 270 kg. The first approach used EPF treatment for pre-concen...

摘要:Abstract(#br)In the context of recovering Ni from pyrrhotite tailings though a (bio)leaching process, Part 1 of this investigation explored a strategy to concentrate iron from the residual jarosite-goethite assemblage using controlled release of reducing gases from biomass t...
