extraction of titanium chemguide

Why is this extraction process used? 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.

Extracting Lead Materials from Ore

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process. First the lead ore is ground into small particles that are less than, giving the ore a texture similar to table salt.
