- mill for extraction of metals
The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.

The commercial extraction of metals from minerals at low cost and minimum effort is the main motto of Metallurgy. The minerals are called ores. Flux is the substance that is added to the charge in the furnace to separate the gangue (impurities). Process of purification of metals and the formation of alloys are the basic areas of Metallurgy.

The extraction of the metals from the calcined or roasted ore consists of two steps i.e., removal of earthy impurities and reduction of the ore to metal. The different methods applied for carrying out the concentration of ores are useful to separate only a part of gangue and the ore still contains some earth impurities.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

The Process of Metal Extraction from Ore Metals are produced when metal oxides have their oxygen removed. The process of metal extraction from ore is dependent on the reactivity of the metal. Highly reactive metals are extracted by electrolysis. In order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum.

Material in process often cannot be weighed without a disturbance of continuity; consequently, mill control must depend upon the sampling of material in flux. From these samples the essential information is derived by means of analyses for metal content, particle size distribution, and content of water or other ingredient in the ore pulp.
