Metals: THE EXTRACTION OF METALS FROM THERE ORES
The more reactive the metal is, the more difficult and expensive the extraction becomes. That means that you are having to use a very expensive reducing agent to extract the titanium. As you will see if you read the page about titanium extraction, there are other problems in its extraction which also add to the cost.

However, the cost of the extraction and recovery process is such that the value of recovered chemicals or metals will only pay 20%-30% of estimated annual total cost. The major cost factor is the expense of reagents for recovery of chemicals, and cost reduction would be most readily achieved by developing better methods for treating extract solutions.
