Would anyone have any new information/photos on the new rail line
that is being built by the chinese from the new iron ore mine to the coast?

Thank you,

Leon

Hi, I think you mean the line in Guinea Conakry.rsther than Equatorial Guinea.bIt is adjacent! Hope this link helps.

How China Unlocked a West African Mine to Reshape the Global Iron Ore Trade

Against all odds, Guinea’s $20 billion Simandou megaproject, including a 600-km railway, a new Atlantic port, multiple tunnels and bridges, and a twin set of mines, stunned the global mining world.

Hello and good afternoon Mr. Farnworth,

Yes, that is the one I was referring to. Using rail for this it is terrible waste of money on the Guineans part as I explained to the people doing
research for a better transportation method for the iron ore is to use the Pneumatic Capsule pipeline method of mining mass transportation
to move the iron ore using a circular Pneumatic Capsule Pipeline from the mine to the coast using a vacuum to pull the capsule liners from the mine while using a low pressure air stream to push the capsule liners at the same time. by using the combined weight of the capsule liners and the weight of the finely crushed iron ore to its advantage it increase the throw weight of the payload to its ultimate advantage propelling the capsule lines from the mine to the coast in a circular or rectangular concrete pipeline at 30 miles per hour at 95% or higher efficiency as the vacuum pulling weight of the capsule liner and it payload is also being pushed by the air stream behind it.

The sealed capsule pipeline allows the vacuum to be maintained at the maximum water gauge pressure while at the same time the forced draft behind it is pushing against the rectangular capsule liners rear gasket that seals the capsule liner against the pipeline walls.

They would have spent considerably less money than they are now as all they would have needed to build is an access road and an above ground pipeline system that simply uses air to move the capsule liners and the iron ore by pipeline that does not require tunnels and can be routed everywhere as long as the pipeline route deviation does not exceed 5% in any given arc. The low percentage is needed soley to maintain the
95%+efficiency of the system.

The Prague conference paper describes how 2 systems were developed in detail and how the Karasawa Limestone system is operating today 25 years after it was built delivering 2 million tons of Limestone aggregate.

Hello Leon

Thank you for your reply.

It seems so often to be the case that high cost projects somehow trump lower cost scheme when work in Africa is being considered.

Best wishes

Roger

Good morning to you Mr. Farnworth,

Sadly, I am very sure wheels were greased.

The Guinea government will find out much too late that they
have lost out and will have no opportunity for 100% ownership
of these projects using the Build Operate Transfer method of ownership.

The <48% efficiency of these operations will kiss their potential profits goodbye.

I just shook my head when I saw the total amount of belt conveyor they are
going to use in these operations then yelled to myself, FOOLS.

Respectfully,

Leon
