హెమటైటి ప్రగలనం నందు ద్రవకారిగా ఉపయోగించునది ఏది?
(1) SiO2
(3) CaCO3 (4) FeSi03
(2) Casio,​

Answer 1

Answer:

cacophony is the right answer

Answer 2

Calcium Carbonate as Flux used for Smelting of Haematite

Explanation:

• Haematite is an iron ore from which iron extract along with impurities

• Flux helps to remove impurities by forming slag

• Flux which we use to remove impurity is limestone

• Smelting is a process to extract the iron from the haematite iron ore

• Limestone first form calcium oxide by decomposing itself.

• Then the calcium oxide forms slag by combining with silica impurity. By forming slag it can removed easily.
