CHEMISTRY MASTER: UNIT 10 METALLURGY

UNIT 10 METALLURGY. All material objects are composed of elements. There are about 118 elements known so far out of which 92 occur in nature while the rest are man-made. The elements are broadly classified into metals and non-metals. About two-thirds of the elements are metals. The elements generally occur in native and combined states.

In the holding tank, the moderate agitation produced by pumping would decrease the settling rate, and the smaller solid concentrations may increase the settling rate. However, a great deal of settling, 60 to 80 wt-pct, does occur, so that only the finer fraction which has an extremely slow settling rate must be filtered.

Electrolytic Refining - Mineral Processing & Metallurgy

Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode. In this setup, an electrolyte (metal salt aqueous solution ...

Hydrometallurgy - Wikipedia

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.
