Loricae are thick and not compressed, impregnated with lime (CaCo 3) and iron compounds.Cells are ovoid to spherical in shape, with two equal flagella, two contractile vacuoles at the base of the flagella, a stigma, and a cup-shaped chloroplast with a single basal pyrenoid (Ettl, 1983).The two flagella are projected through a common opening of the lorica.
In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates. Bentonite is the most widely used binder. However, it is considered as an impurity due ...
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.
This element is known as "red iron ore", and is dark red with a brown tinge to grayish-red. Limonite is a mineral with an iron content of 85%. This element is a crystal hydrate, which is yellow, or more rarely brown. Limonite is known as …
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary …
An iron ore sample is composed of 69.94% iron and 30.06% oxygen. What is the molecular formula of the compound if its molar mass is 159.7 g/mol? CLUE: Fe2O3 (also known as Iron (III) Oxide (55.85)2 + (16.00)3 = 111.70 +48.00 = 159. 70 g/mol Yung alternative solution po sa "clue" yung hinahanap ko. Thanks!
Iron – Heavy Metal. Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.
Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most …
Iron compounds are produced on a large scale in industries. Ferrous Sulfate, FeSO 4 7H 2 O and Ferric Chloride, FeCl 3 are two of its compounds which are produced on a very large scale. One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III).
Hematite is an ore of iron. Iron compound present in hematite ore is iron (III) oxide. The formula of the ore is Fe 2 O 3.
