Question

In Bessemer converters, oxides of manganese and silicon are removed as manganese silicate.
A.True
B.False

Answer 1

To answer this question, recall the concept of extraction of metals. The study of metals, their ores and its extraction is known as metallurgy.
The Bessemer process was the first industrial process that was inexpensive and was used for production in bulk of steel, from molten pig iron before the open blast furnace was developed.

Complete step by step answer:
The key principle is the removal of impurities from the iron using the process of oxidation of molten iron by air being blown on it. This process also results in an increase of temperature of iron mass and maintains it in the molten state.
In Bessemer the manganese and silicon oxides eliminate manganese silicate.
The conversion process takes nearly 20 minutes. The progress of oxidation is judged by the appearance of the flame at the mouth of the converter.

Hence, the statement given in the question is true. Correct option is option A.

Note:
Do not confuse between the Bessemer process and Bessemer converter. The Bessemer process was developed for production of steel and it was the first inexpensive industrial process for the mass-production of steel from molten pig iron before the development of the open-hearth furnace. The key principle is a removal of impurities from the iron by oxidation with air being blown through the molten iron. The Acid Bessemer suffered a decline in favour of the Acid Open Hearth steel process, mainly due to economic factors. Also the open-hearth process gives better quality steel than the Bessemer process.
