Which of the following options are correct?
Which of the following options are correct?
The correct option is B Cast iron is obtained by remelting pig iron with scrap iron and coke using hot air blast.
Option (A):
Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron with scrap iron and coke using a hot air blast.
Option (B):
Silver is extracted by smelting or chemical leaching, not by cationic complex.
Option (C):
Nickel is purified by the Mond process, not by zone refining.
Option (D):
The Van Arkel method is a metallurgical method used to refine zirconium and titanium metal.
The halogen used in the van Arkel method for refining zirconium and titanium is a solid at room temperature and when kept in an open vessel, it sublimes to violet-colored irritating vapors.
