Answer: The first cotton mill in India was set up as a spinning mill in Bombay in 1854. By 1900, over 84 mills started operating in Bombay. Mills came up in other cities too. The first mill in Ahmedabad was started in 1861. A year later a mill was established in Kanpur, in the United Provinces. Growth of cotton mills led to a demand for labour.

6.3.1 Brief History of Primary Smelting Processes. Smelting processes were developed initially for fusing high grade lump ore either as produced by the mine or obtained by hand, or in the case of nickel pyrrohtite ores by magnetic cobbing. Such lump ores were suited to smelting in a low shaft blast furnace with coke.

Smelting is an energy-intensive process used to refine an ore into usable metal. Most ore deposits contain metals in the reacted or combined form. Magnetite (Fe3 O 4 ), hematite (Fe 2 O 3 ), goethite (αFeO [OH]), limonite (the generic formula for limonite is FeO [OH].nH 2 O), and siderite (FeCO 3) are iron ores, and Cu 5 FeSO 4 is a copper ore.

Smelting is the process of removing a metal element from mined ores. Most metals are found as veins in rocks, or as parts of other elements. Smelting is the first step of extraction. Melting is what is done with metal alloys or pure metals. Scrap is melted, ore is smelted. Pig iron is the rough iron ingots created from iron ore smelting.

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Gold on the other hand is majorly an inert element, it will not take part in the oxidation process. The gold will therefore sink down easily in its molten form. The oxidized impurities (aided by Borax) will float up as slag and get collected. Therefore, the efficiency of the smelting process is highly increased and there is improved separation.
