Mineral Processing Techniques - Iron, Vanadium, Titanium

Using techniques that break the linkage?

This sounds like a layman query. I will provide a rough and general answer at that level. In metals extraction there are basic areas of process operations:
Minerals Processing : Solids handling Processes

Hydro-metallurgy : Chemical Processes using water.

Pyrometallurgy : Chemical Processes using heat.

The metals you mention will require all of the above and a bit more. In order of difficulty of extraction, I should let you know : Iron is relatively simple but for a company that has access to the equipment such as furnaces (expect high temperatures of 1600C). By all counts, titanium extraction and titanium metal production are extremely difficult. So much so that only a few countries in the world are capable of producing the metal. The same applies to Vanadium Metal as it behaves in a similar way to Titanium.

If you are talking about ore concentration and exporting the concentrate to Titanium or Vanadium producing countries then this is another story. This would be more realistic. This means that you would use mainly minerals processing techniques such as Crushing & Grinding, Milling, Screening, Flotation, etc. Do follow on Wikipedia.

If you are talking the of going the "full monty" - in other words if you want to produce the metal (Titanium or Vanadium) as your product then think several times again! Outside of 5 or 6 countries (Japan, USA, UK, China, etc) no other countries have the capability to manufacture these two metals. Some countries like Canada & South Africa are in a position to supply the market with Titanium bearing ores but yet are not in a position to produce the actual metal as they currently lack the technology and have not invested in such manufacturing plants.

I wonder, why might you be interested in these processes. Does it mean that you have access to or have knowledge of a relevant mineral resource? If so, you should check the factors such as ore concentrations, etc before going further. Then I would suggest that you either do research (e.g. on Wikipedia). Alternatively you might want to get expert opinion or advice.

The types of operators that follow up such queries can often be traders who have connections with a 3rd party that owns a resource. Problem is what does the trader bring to the table? There are only 3 pieces to the equation in such ventures:
a) The Concession for the exploiting resource.

b) The Money to finance the Venture.

c) The Method - The Technology.

Such ventures only start to make sense when all 3 of the above come together simultaneously. In addition, it must be financially viable.

Hope I shed some light on the query.

If you type in on a google search: iron, titanium, vanadium processing, you will get a reference to every Chinese manufacturer of equipment to do the job as it is presently done.
