CF&I on the Monarch Branch

Hello Guys.

So I got a wonderful book from my brother and sister in law for Christmas on the Monarch Branch (Book is called Trails among the Columbine - Monarch Branch). I have a few questions on the CF&I facility at the end of the line.

1) I know that I was a quary, but what did they do with the limestone? I was reading in the book that the product mostly shipped to Pueblo and it had two different grades of material.
2) What were the two different grades of material used for?
3) Does anyone know where I can get plans for the loading facility portion of the plant?

Thanks for the help gents.
