What is the role of limestone during the extraction of iron from haematite
During the extraction of iron from haematite ore, limestone acts as a flux. Limestone decomposes froming CaO which reacts with silica forming slag. C a C O 3 → C a O + C O 2 C a O + S i O 2 → C a S i O 3 (s l a g)

Samples were submitted for three different analyte extraction or decomposition procedures; microwave assisted digestion (MAD), extraction by heating on a metallic plate and ultrasound assisted extraction (US).
what is the role of limestone in extraction of iron??
5 Answers. The main role of limestone in extraction of iron is to decomposes in hot furnace and form the calcium oxide. Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide.

Iron and manganese removal from groundwater using limestone
2020/2/15Laboratory-scale experiments were carried out to investigate the removal efficiency of iron and manganese from groundwater using limestone filter assisted with iron-oxidized bacteria. Column studies were conducted using limestone with a particle size between 0.6 and 2.36 mm and run at different operation times with a flow rate of 4 L/h and retention time of 2.94 min. Iron-oxidized bacteria

Limestone means any rock formed mostly of calcium carbonate (CaCO 3), but to geologists, limestone is only one of several types of carbonate rocks. These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO 3) or dolomite (calcium-magnesium carbonate, CaMg[CO 3] 2) or both.

2013/5/2Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.
