Flotation recovery in geometallurgical modelling is usually predicted based on relationships developed from batch flotation testing of different ore types. These batch flotation tests are usually performed at a constant set of operating conditions and at a fixed feed grind size P80. Usually the laboratory feed grind P80 is that which is expected to be produced in the full-scale flotation circui...

INTRODUCTION The objective of this qualitative case report was to describe experiences of flotation-Restricted Environmental Stimulation Technique from the perspective of a woman with Attention Deficit Hyperactivity Disorder, Aspergers syndrome and experiences of depression and distress. CASE PRESENTATION The respondent is a 36-year-old woman from Sweden, assessed and diagnosed by a neuropsyc...

Two biodegradable quaternary ammonium salts were synthesized and used as cationic collectors in processing iron ores by froth flotation. The flotation behaviors of iron minerals with the new biodegradable quaternary ammonium collectors were investigated by micro-flotation tests of quartz (SiO2) and magnetite (Fe3O4). It was observed that the new biodegradable collectors were effective in separa...

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 μm based on the mi...

The flotation behaviors of perovskite, titanaugite, and magnesium aluminate spinel (MA-spinel), using octyl hydroxamic acid (OHA) as the collector, were investigated using microflotation experiments, zeta-potential measurements, Fourier transform infrared (FT-IR) analyses, X-ray photoelectron spectroscopy (XPS) analyses, and flotation experiments on artificially mixed minerals. The microflotati...

Iron ore concentrate is enriched by flotation prior to form iron ore green pellets in order to reduce phosphorus content in the ore concentrate. A flotation reagent is used in this process and it is known to incorporate air bubbles and eventually deteriorate the strength of the pellets. These bubbles were therefore characterized both qualitatively and quantitatively by cryogenic scanning electr...

Flotation of minerals, an important part the chain metals production for our society, needs huge amounts water. This industry can contribute to sustainable use water and circular economy development by utilizing its own wastewater. However, reuse clarified without additional treatment may cause worsening flotation results. Electrocoagulation this with mild steel sacrificial anodes, complemented...
