Drilling companies are trying new technologies all the time to get more oil out of existing wells

Fossil Fuel extraction There is an interesting product based on bauxite that is used to

increase the porosity of the area around an oil well. It is called proppant and it is produced also in India.

Drilling deeper wells was a challenge for Russians long ago when they opted for metals with better strength to weight ratio to drill deeper such as aluminum drill pipe.

drill deeper such as aluminum drill pipe. Gasification of fossil fuels is getting a new boost with the

invention of superheated steam treatment of fossil fuel creating high caloric value gas but leaving sulfur and other elements in the ash

Gasification of Pet Coke will be tested in India in a new pilot plant. And we plan to test Lignite as well.

Metallic and Non Metallic Mineral Extraction

The most spectacular successes here are the selective chemical extraction methods developed such a cyanide extraction of gold and other elements

and other elements But then there are also companies that have

developed many solvent extraction methods for other metals.

Who are the researchers that are looking for new and better ways to extract? Large chemicals companies such as Nalco

and Cytec and many others developed and are still developing new additives, solvents

12

are still developing new additives, solvents etc.etc.

Why: Because there is great commercial promise for these developments.

And note these are never developed in government research labs.

So what is the message here for Gujarat and India.

Don�t reinvent the wheel Invite the successful companies to come to

India and Encourage Indian entrepreneurs to set up

Encourage Indian entrepreneurs to set up mineral extraction business together with those that already have the experience and know-how.

Bauxite in Gujarat

14

Is there enough left? As most of you know Gujarat has bauxite deposits

or at least had significant deposits. Over the last 10 or so years heavy exporting was done so we are not so sure if sufficient deposits remain to warrant a alumina refinery. Fortunately this export has now

alumina refinery. Fortunately this export has now been stopped. Gujarat�s great leader Shri Narendra Modi sanctioned an export stop last year and furthermore gave custody of all bauxite deposits to GMDC

Now we have a chance to reassess the bauxite reserves and qualities available.

Beneficiation to find more usable reserves

The quality of the remaining bauxite may be not as desirable as before.

So why do we want to built in Gujarat. The main reason is that there is the political will to

main reason is that there is the political will to built and alumina refinery.

And as we are determined to make it work we are now contemplating a bauxite beneficiation step, to be able to use the lesser quality bauxite also.

CAC As the bauxite in the deposits are not very

homogeneous we were told we likely to come across some high grade low iron bauxite.

To not waste this good bauxite on alumina refinery we plan to utilize it to make a high refinery we plan to utilize it to make a high added value product called Calcium Alumina Cement. This fast setting ceramic material is needed in Gujarat�s industrial expansion

Alumina extraction from Bauxite

Let�s stick for a moment with the extraction of alumina from bauxite which I happen to have worked on for most of my career.

worked on for most of my career. Also here the one with the best extraction

technology and the lowest cost base has a chance of survival, like in any other mineral extraction business

India needs

5 million tons additional installed alumina capacity in the next 5 years and double that in the following 5 years

We want to set up soon one alumina refinery in Gujarat and will use the best available technology.

23

Gujarat and will use the best available technology. Not because we are so proud that we know this technology but because it gives the best economical extraction and responsible mineral reserve management. We plan not to waste one gram of bauxite or use one kWh more energy than is strictly necessary.

What India gets

These are commercial incentives to the project but guess what: These service the government goals also: To best utilize the minerals resources for the benefit of the

25

minerals resources for the benefit of the people of the state. The government gets the best deal without being in the business themselves.
