  Kroll process - Wikipedia, the free encyclopedia
The Kroll process is a pyrometallurgical industrial process used to produce metallic titanium.
It was invented in 1940 by William J. Kroll in Luxemborg.
The Kroll process has not been replaced by a molten electrolytic process because of redox recycling, diaphragm failure and dendritic deposition in the electrolyte solution.

Kroll is considered the "father of the titanium industry" for his breakthrough work in the 1930s to extract the metal from its natural state and transform it into a useful product.
Kroll died in 1973, but his process - later named the "Kroll Process" - made possible such modern-day products as jet engines, artificial hips and knees, golf clubs, watches, and marine equipment.
Kroll and his fellow inductees bring the number of inventors now in the Hall of Fame to 151.

 The FFC Cambridge Process
The Fray-Farthing-Chen (FFC) Cambridge Process is a new process for the extraction of metals and alloys from their solid oxides by molten salt electrolysis.
Titanium produced by the FFC Process may be in the form of a powder or sponge.
The FFC titanium sponge is also structurally very similar to the Kroll titanium sponge produced by a pyrometallurgical method invented by William J. Kroll in 1940.

 William J. Kroll - Wikipedia, the free encyclopedia
He is best known for inventing the Kroll process in 1940, which is used commercially to extract metallic titanium from ore.

 The Kroll Process
To produce a useable form of titanium, the basic ore, usually rutile, is converted to sponge by charging the ore in a chlorinator, then passing chlorine gas through the charge.
The next stage of the process requires the titanium sponge to be crushed and pressed before being melted in a consumable electrode vacuum arc furnace at extreme heat.
The kroll process is the refining of titanium from its natural ores.

 35858. Extracting elemental titanium from Titanium Dioxide [Kentucky]
This process is called the Kroll Process and has been around for many years.
However, there is a newer process called the FFC Cambridge Process, where the titanium salts and oxides are melted at a high tempertaure and the molten mixture is electrolysed to produce titanium metal at the cathode.
This process was used to weld the train tracks when they built the trans America railroads in the nineteenth century.

 (Former) Powell Research Group
Novel primary metal reduction processes, such as electrolytic smelting and refining of steel, involve liquid electrolytes (typically molten salts) and reaction products at the cathode.
A new electrolytic reduction process for making titanium is being designed as a possible supplement or replacement for the Kroll process.
This process is therefore expected to result in considerably lower cost and environmental impact than the current Kroll process.

 Betterton-Kroll process - Wikipedia, the free encyclopedia
The Betterton-Kroll process is an industrial process for removing bismuth from lead.
Calcium and magnesium are added to a molten lead-bismuth bath, the resulting bismuth compounds have higher melting points and lower densities than the lead, and can be removed as dross.
Temperature used in the process is about 380-500°C. The other major processes for separating the two metals are by fractional crystallization and by the Betts electrolytic process.
