The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+. The solvation number , n , determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table .
Iron(II) chloride tetrahydrate, FeCl 2 ·4H 2 O. In chemistry, iron(II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+.
The affordability of water charges can be measured by macro- and micro-affordability. [16] Macro-affordability" indicators relate national average household water and wastewater bills to average net disposable household income. In OECD countries it varies from 0.2% (Italy and Mexico) to 1.4% (Slovak Republic, Poland and Hungary).
Water Supply and Sewerage Authority or WASA is the main body administering Water supply, Drainage and Sanitation system in Bangladesh. [1] It was established in the year 1963 as an independent organization, under the East Pakistan ordinance XIX. At present WASA operates according to the WASA act 1996. [2]
EDTA is used to solubilize iron(III) in water. In the absence of EDTA or similar chelating agents, ferric ions form insoluble solids and are thus not bioavailable. [1] Together with pentetic acid (DTPA), EDTA is widely used for sequestering metal ions.
The Iron and Steel industry in India is among the most important industries within the country. India surpassed Japan as the second largest steel producer in January 2019. [ 1 ] As per worldsteel , India's crude steel production in 2018 was at 106.5 million tonnes (MT), 4.9% increase from 101.5 MT in 2017, which means that India overtook Japan ...
