We have had in our courtyard here at work a plant that was referred to by the name "iron plant". It had a broad leaves that came to a point, was not bushy (no branches to it) but rather kept on adding leaves so it filled the pot. It was donated by someone who had gotten it from her grandmother. It was very old & had a dense root structure - it was in a about a 3 ft wide by 3 ft deep pot.

It developed mites & its leaves were turning brown from the tips. It being so big & hard to work with we discarded it. Of course then the person who donated it many years ago found out & is very unhappy with us. We would like to try & replace it with some new, healthy stock but it is not something found locally, as far as I know. Especially since I don't know its "real" name. Any help in identifying it and perhaps where I can get a replacement for it would be GREATLY appreciated.

It sounds like what you had was a "Aspidistra elatiory" commonly known as a Cst Iron Plant. Even when neglected, they will do very well in a dull corner of the house and thrive where other plants would probably die.
If you do a KEYWORD SEARCH, you should be able to find out where you can buy them if you don't get any answers here. Depending on where you look, they can be pricey.
For future reference, these plants don't like direct sun, give them a more shaded/dapple area. Spidermites love hot & dry places to infest a nice juicy plant.
