Metal ores are generally oxides, sulfides, silicates (Table 12.3.1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 12.3.1 ). The ores must be processed to extract the metals of interest from the waste rock and from the ore ...
During the electrolysis, titanium oxycarbid (TiC x O 1-x) electrochemically dissolves in molten salts with high dissolution ratio (extraction rate), low rate of the residual, and high current efficiency. (3) During the electrolysis with the same molten salts bath, titanium metal deposits at the cathode with high current efficiency. (4)
Titanium was analyzed by XRF, using the calibration curve method to calculate the extraction percentage in all the experiments by the following equation: %X = Ti f Tim 100 where Timis the initial amount of Ti in the ore, and Tifis the quantity of Ti from leach liquors.

Book excerpt: This collection presents papers from a symposium on extraction of rare metals from primary and secondary materials and residues as well as rare metals extraction processing techniques used in metal production.
Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle. That means that you have to use an alternative reducing agent.
Refining a metal can be accomplished by electrolysis or zone refining. Certain ores such as those of copper and titanium require special treatment before they can be refined. The extraction of iron ore …

Currently titanium is extracted from titanium oxide ore by a series of process steps involving: 1) chlorination of oxide concentrate to prepare titanium tetrachloride (TiCl4), 2) reduction of TiCU by magnesium metal (Kroll process), 3) vacuum distillation/leaching of reduced mass. Electrolysis of the by-product MgCLz is a parallel …
