Metallurgic Processes | Boundless Chemistry
Key Points. Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores ( .

Mining. The pyrite is then processed to remove the iron, which is sold for a profit. The sulfurbearing waste material that's left behind after the iron is taken out is then just discarded or piled up on the ground. Before mining, the sulfide materials naturally in the ground pose little threat to the environment.

Abstract. Lake water, pore water, and sediments were sampled in a seasonally stratified lake affected by coalmining drainage. Contrasting geochemical processes of iron and manganese in summer were investigated by studying the seasonal distributions of iron and manganese species in the water column, pore water, and sediments.

Iron removal by physical chemical way
Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3). The occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc.

How Is Iron Extracted From the Earth? |
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Pollution from Mining
Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfurcontaining materials in the presence of water leads to highly acidic solutions.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
