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 soluble salt minerals such as potash, trona and borax exhibits similarities because all are conducted in their brine solutions. The most commercially important boron minerals in the world are borax (Na2B4O7.10H2O), colemanite (Ca2B6O11.5H2O), ulexite (NaCaB5O9.8H2O), and kernite (Na2B4O7.4H2O). Most of them contain low grades when mined and must be upgraded by mineral processing te...

The Swan-Ganz balloon flotation catheter was introduced in 1970. It can be placed at the bedside within a few minutes even in critically ill patients. Although placement of these catheters is not difficult, some training and experience are required to avoid complications and for proper interpretation of the hemodynamic data that can be obtained by pulmonary artery catheterization. Because of th...

In this study, hydrophobic talc nanoparticles were applied as a novel class of solid flotation collector. The aim of this work was to understand the effect of talc nanoparticles size and dosage on the quartz flotation recovery. X-ray analysis, dynamic light scattering, and scanning electron microscopy were conducted. Flotation tests were performed in modified a Hallimond flotation cell. The Zet...

Pain is a major public health problem and the needs for more differentiated and flexible treatment options are obvious. The purpose of the present study was to examine, for the first time, experiences from long-term flotation Restricted Environmental Stimulation Technique (REST) made by a patient with chronic Whiplash Associated Disorder (WAD), grade IV. The patient of the present study was a m...

A laboratory flotation column equipped with Venturi aerators and an adjustable froth removal system was used to study the effect of calcium soap and a mixture of calcium soap/alkyl phenol ethoxylate surfactant on ink and fibres transfer during flotation de-inking of a 50% old newprint (ONP) / 50% old magazines (OMG) recovered papers mixture. Mass transport phenomena determining the yield of the...
