Absorption Zone In The Extraction Of Iron

The Extraction of Iron - Chemistry LibreTexts

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.

Iron Absorption - an overview | ScienceDirect Topics

Iron absorption occurs through the differentiated epithelial cells (enterocytes) of the mid and upper villus, and predominantly in the proximal part of the small intestine. 17–20,22,37 The proteins involved in this process are listed and briefly described in Table 60.1.The immature enterocytes of the intestinal crypts handle iron quite differently from their mature counterparts (as noted above).

(i) The technique of zone refining is based on the principle that the impurities are more soluble in the molten state of metal than in the solid state. Silicon , boron gallium , indium etc. can purify by this process. (ii) Ores of copper contain iron oxide as an impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag.

Absorption (chemistry) - Wikipedia

In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface (as in the case for adsorption).A more general term is sorption, which covers absorption, adsorption, and ...
