They at the plant Freeport-McMoRan "EL ABRA" (Chile) promise to get "fine copper in concentrate"? It's impossible! Copper concentrate contains minerals (e.g. chalcopyrite ...)!

 From the series of publications  

"So they create a fairy tales for the investor" -  

"They draw up the necessary documents 

and begin to search for the simpleton..."

FREEPORT MCMORAN "EL ABRA" (Chile)

Owners:   
Freeport-McMoRan, USA (51 % )
Codelco, Chile (49 %)


Let's count together:

They promise to have a productivity of 150000-240000 tons per day.

If the plant works 365 days a year, 24 hours a day, the plant’s productivity will be 54.7-87.6 million tons per year.

The copper content in the ore is 0.45 %.
The maximum amount of copper (theoretically possible) that they can extract from their ore is 246400-394200 tons per year of copper.

They promise to get 450000 tons per year of copper in concentrate.

How is this possible?
How can one extract and sell something that does not exist in principle?

How can copper recovery at a plant "EL ABRA" (Chile) be 170-114 %? (The recovery cannot be more than 100%!)

It is theoretically impossible to produce such an amount of copper at the plant and they will have a deficit of 203600-55800 tons of copper in concentrate per year.

IMHO: This is not copper which you can sell on the exchange!
This is a copper concentrate that requires additional processing! Unknown copper concentration in concentrate.

In reality, the shortage of copper concentrate will be more than 611000-167000 tons per year.

Moreover, with a capacity of 150000 tons per day, they can never get 340000 tons per year of copper in concentrate. Shortage of 94 tons per year of copper in concentrate.
