Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is NOT correct about The Bessemer Process?
A
The key principle is the removal of impurities from the iron by oxidation.
B
Air was blown through the melton iron.
C
The process was operated from molten pig iron.
D
The Bessemer Process was the first inexpensive industrial process for the mass production of iron.
Explanation: 

Detailed explanation-1: -The bessemer process reduces molten pig iron in so-called bessemer converters-egg-shaped, silica, clay, or dolomite-lined containers with capacities of 5 to 30 tons of molten iron. An opening at the narrow upper portion of the bessemer converter allows iron to be introduced and the finished product to be poured out.

Detailed explanation-2: -The Bessemer process greatly reduced the cost of producing steel. Steel, which is lighter and stronger than iron, became an important material as America industrialized.

Detailed explanation-3: -Which of the following was an impact of the Bessemer process? It allowed steel to be produced far more cheaply and quickly.

Detailed explanation-4: -One difficulty with Bessemer’s process was that it could convert only a pig iron low in phosphorus and sulfur. (These elements could have been removed by adding a basic flux such as lime, but the basic slag produced would have degraded the acidic refractory lining of Bessemer’s converter.)
