A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as ...

The chemodynamics of Cu(II) complexation by humic acid is interpreted in terms of recently developed theory for permeable charged nanoparticles. Two opposing electric effects are operational with respect to the overall rate of association, namely, (i) the conductive enhancement of the diffusion of Cu2+, expressed by a coefficient fel, which accounts for the accelerating effect of the negative ...

Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.Metallurgy encompasses both the science and the technology of metals. That is, the way in which science is applied to the production of metals, and the engineering of metal components used ...

Metallurgy - Metallurgy - Metalworking: Metals are important largely because they can be easily deformed into useful shapes. Literally hundreds of metalworking processes have been developed for specific applications, but these can be divided into five broad groups: rolling, extrusion, drawing, forging, and sheet-metal forming. The first four processes subject a metal to large amounts of strain.

Fig. 1 shows the effect of pH on the flotation behavior of anglesite in the presence of 21.75 mg potassium amyl xanthate/g anglesite (2.5 × 10 −3 M), 16 mg Aerofloat 242/g anglesite and 20 mg Aerophine 3418A/g anglesite. Flotation recovery in the presence of xanthate was low at pH 5.5 and increased with pH up to ca. pH 10 and dropped at higher pHs, consistent with the findings of others ...

Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.

Tungsten is a metal that is stronger than steel and a high melting temperature. It is also used to make saw blades and used in welding. Uranium is a highly radioactive element. It is used in cancer treatments, X-rays, military weapons and fuel for the space shuttle.
