The performance of flash furnace burners can be evaluated quickly and efficiently using CFD modelling. Gas flows are modelled using the conventional Eulerian approach, while Lagrangian particle tracking is used to model the flow of solid feed through

The reaction shaft is the heart of a flash smelter. Current knowledge of the combustion of concentrate and ancillary fuels (coal, oil, and gas) in flash smelter shafts comes from laboratory studies, plant measurements, and physical and mathematical m

To simulate the behavior of arsenic during the practical roasting of copper concentrate, a modified free-energy minimization method was developed. The calcine was assumed to be a pseudosolid solution in which the nonequilibrium arsenic species are co

A modified thermodynamic calculation procedure was used to simulate the behavior of a number of minor components in sulfation roasting. To account for uncertain mineralogy and probable non-equilibrium situations it was assumed that the calcine formed

Single-phase turbulent fluid flow inside and below a burner model was studied to better understand the fluid flow processes occurring inside and below flash smelting burners. The effect of Reynolds number and temperature on the axial velocity profile

Water-model experiments were carried out on 1:14-scale models of venturi, distributor, and jet-flow burners to ascertain flow patterns at varying Reynolds numbers (60,000 to 507,000) using time-lapse streak photography and video streak photography. D

A mathematical model of the heat flow to a Sirosmelt lance is presented, which predicts lance wall and air temperatures and the thickness of the slag layer on the lance. By measuring the distribution of wall temperature and slag thickness on an opera

This study examined the moderating effects of sociotropic cognition (SC), a nondefensive need for approval, on stress-induced cardiovascular responsiveness (CVR) in women. Sixty-seven college-age females had blood pressure (BP) and heart rate (HR) mo

Currently, no accepted medical therapy for patients with primary sclerosing cholangitis (PSC) is available. Case-control studies have shown an inverse association between PSC and smoking behavior, suggesting that nicotine might have a beneficial effe
