Which of the following statement(s) is (are) correct about slag?a)The ...
(A) FeSiO3
(B) CaCO3 →CaO + CO2.
CaO + SiO2 → CaSiO3.
These reactions take place in slag formatin zone at temperature 1275 K.
(C) True statement.
(D) Infusible matter + Flux = Fusible matter (slag).
(B) CaCO3 →CaO + CO2.
CaO + SiO2 → CaSiO3.

Slag in Metallurgy
Slag is a byproduct of metallurgical processes and is formed when impurities are removed from molten metals. It is mainly composed of oxides and silicates and can have various chemical compositions depending on the process and the metal being extracted.
Chemical Composition of Slag
a) The chemical composition of slag obtained in the extraction of copper from copper pyrites is PbSiO3. This statement is incorrect as the chemical composition of slag in copper extraction is mainly composed of iron, silica, and other impurities.
b) The calcium silicate, CaSiO3 is obtained in slag formation zone in the extraction of iron from haematite ore. This statement is correct as calcium silicate is one of the main components of slag in iron extraction.
c) In blast furnace / Bessemer converter, the upper layer of molten liquid (i.e. molten metal) is of slag. This statement is correct as the lighter slag floats on top of the denser molten metal in the furnace or converter.
d) The slag is fusible matter. This statement is correct as slag is a molten material with a lower melting point than the metal being extracted.
Conclusion
Slag is a byproduct of metallurgical processes and its chemical composition varies depending on the process and the metal being extracted. Calcium silicate is a common component of slag in iron extraction, and slag is a fusible material that floats on top of the molten metal in the furnace or converter.

Which of the following statement(s) is (are) correct about slag?a)The ...
In Haematite ore chief impurity are silica alumina and phosphates
CaO is added to the Haematite ore. while adding the the mic into the blast furnace
So in the slag formation zone CaO + SiO2 --> CaSiO3 is formed
slag floats on the molten metal and can be separated
and slag is fusible ( can be melted)
