This technique involved injecting air into molten iron to remove the carbon and other impurities.
It mixed impurities in the iron ore enough to eliminate the problem of weakening.

A faster and more affordable way of making steel, using air blown in through the iron that caused impurities to burn off.
Sir Henry Bessemer
The method to make steel. The Bessemer method blows air into the hot iron ore to remove the impurities from the ore and this makes steel.
Iron ore. Bessemer figured out that shooting air into the molten iron would remove the impurities and that made steel.
The process to purify ore and produce steel is known as the Bessemer process, which was invented by Sir Henry Bessemer in 1856. This process involves blowing air through molten iron to remove impurities and increase the carbon content, resulting in the production of steel.
Iron when extracted from ore is a mixture of carbon and iron. This is very brittle and shatters easily. The Bessemer converter removed the carbon by flushing molten iron with oxygen, thereby removing the carbon and yielding soft iron. The carbon content could then be adjusted creating steel, which can then be tempered to a required hardness. The Bessemer converter made steel possible and permitted major engineering advances.
When Bessemer developed his method of making steel the use of iron ore grew and so did making railroads, multistory buildings, and bridges.
Henry Bessemer developed a way to make steel by melting and burning pig iron. Pig iron is the result of mining and refining iron ore. Before steel, he worked with glass, but his glass making process was not practical.
The Bessemer process produced the lightweight steel needed to build a suspension bridge.
It is a lustrous black to brownish ore (FeTiO3) and is the principal or of titanium. Though as you can see it does have as much Iron in it as titanium. However, there are better ores of iron.
