Preparation of Ultrafine Fe–Pt Alloy and Au Nanoparticle ...

· We prepared ultrafine Fe–Pt alloy nanoparticle colloids by UV laser solution photolysis (KrF excimer laser of 248 nm wavelength) using precursors of methanol solutions into which iron and platinum complexes were dissolved together with PVP dispersant to prevent aggregations. From TEM observations, the Fe–Pt nanoparticles were found to be composed of disordered FCC A1 phase with .

The effect of liquid additives on dry ultrafine grinding ...

· The dry ultrafine grinding of quartz with liquid additives was carried out using a vibration rod mill with a laboratory scale. Liquid additives used were mainly seven alcohols and three glycols with different alkyl groups. All of the experiments were carried out by batch operation, and the variations of specific surface areas of products with grinding time were measured by BET adsorption ...

Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. In this study, we attempt to increase the apparent sizes of target mineral particles, and improve the separation indices, by using a multistage ...

Ultrafine particles | Occupational Environmental Medicine

· Ultrafine particles are generally made from combustion processes in which growth of the particle is from molecules upwards and so these particles can be extremely small, much smaller than the problem particles in dusty trades that have been studied up until now (fig3).4 Ultrafine particles also have important industrial appliions—for example, as ultrafine carbon black—and so there is ...

Development of shear localization in simulated quartz ...

Shear localization in the ultrafine quartz gouge initiated very early before the onset of frictional sliding. Various modes of shear localization were evident, but within the gouge zone R 1 shears were predominant. The density of shear localization increased with cumulative slip, whereas the angle subtended at the rockgouge interface decreased. Destabilization of the sliding behavior in the ...

Mill (grinding)

Quartz or silica is commonly used because it is inexpensive to obtain. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill ...
