  • What is the Kroll Process? Titanium Processing Center

    2017-9-28 · The process of transforming crude titanium from the earth (known as ore) to the type of metal we use in many aspects of our lives is called the Kroll Process. The Kroll Process Kroll Process an overview ScienceDirect Topics,Titanium is extracted from titanium ore using the Kroll Process (magnesium reduction) and emerges as sponge titanium. The titanium used to make Ti–Ni alloys is either sponge titanium itself, or ingots that are made by re-melting sponge titanium.
