    Abstract

    Flash smelting involves complex reactions between copper sulfide ores, silica sand, impurities, and oxygen gas while dropping. In situ observations of particle oxidation (ignition and combustion) under simulated flash smelting conditions can promote an understanding of this phenomenon. However, previous studies were limited by technical difficulties. In this study, in situ observations, two-color temperature measurements, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDS), and thermodynamic equilibrium calculations were used to characterize the oxidation of CuFeS<sub>2</sub> particles under simulated flash smelting conditions. CuFeS<sub>2</sub> particles changed in four phases in oxidation within 300 ms. The first process was ignition (≈ 25 ms) with an average temperature of 2100 °C. This was triggered by fine particles (several μm in diameter) on coarse particles (approximately 50 μm in diameter) and formed sphere particles consisting of two phases (sulfide and oxysulfide, Phase I) or three phases (sulfide, oxysulfide, and iron oxide, Phase II). The second process was combustion (&lt; 300 ms) with an average temperature of 1900‒2000 °C. In addition to the spherical particles, particles surrounded by a flame consisting of two phases (oxysulfide crust and oxide core, Phase III) were observed during combustion. The flame may be generated by the continuous sulfur vapor emitted from the oxysulfide crust, which vanishes after the consumption of the sulfur vapor. Finally, oxide particles (Phase IV), similar to those in the thermodynamic equilibrium phase, were formed.

  • Evaluation of Heterogenous Oxidation Reaction of Copper Concentrate/Pyrite/Silica Sand Mixture by Preheated Oxygen Gas Blowing Reviewed

    A hand-made apparatus to react copper concentrate (Cc)/pyrite (Py)/silica sand (Ss) mixture was developed for an imitated concentrate burner at laboratory scale. An instantaneous (< 1 s) ignition reaction was macroscopically observed by preheated oxygen gas blowing to Cc/Py/Ss mixture with a Fe/SiO<sub>2</sub> mass ratio of 1.1. SEM-EDS analysis was used to observe microstructure and phase distribution in reacted and water-quenched particles. As for the Cc/Ss samples collected at the point close to the gas blowing spot, 70–80 mass% Cu matte phase and heterogeneous slag phase including large amounts of magnetite (Mag) particles were formed. At the lower part from the gas blowing spot with a distance of 275 mm, 60–65 mass% Cu matte phase was confirmed. The area fraction of Mag particles in the slag phase decreased with increasing Py adding concentration in the mixture sample. Our results suggested the concentration and microscopic distribution of Py in the mixture including Cc contributed to control both Cu concentration in matter phase and Mag particle concentration in slag phase.

    Pulsed-laser-induced glass fiber generation has been reported. We demonstrate a novel glass fiber generation technique by continuous-wave laser illumination and reveal the generation mechanism. In this technique, borosilicate glass, metal foil, and a heat insulator are stacked and clamped by a jig as the sample. Glass fibers are ejected from the side surface of the borosilicate glass by laser illumination of the sample from the borosilicate glass side. SEM observation shows that nanoparticles are attached on the glass fibers. High-speed imaging reveals that small bubbles are formed at the side surface of the borosilicate glass and the bursting of the bubble ejects the fibers. The temperature at the fiber ejection point is estimated to be similar to 1220 K. The mechanism of the fiber ejection includes the following steps: the metal thin foil heated by the laser increases the temperature of the surrounding glass by heat conduction. Since the absorption coefficient of the glass is increased by increasing the temperature, the glass starts to absorb the laser irradiation. The heated glass softens and bubbles form. When the bubble bursts, molten glass and gas inside the bubble scatter into the air to generate the glass fibers.
