The rock is drilled and blasted then moved to the surface by truck belt conveyor or elevator. Once at the surface the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods which generally cost less than underground methods.
Slag - Wikipedia
In nature iron copper lead nickel and other metals are found in impure states called ores often oxidized and mixed in with sili es of other metals. During smelting when the ore is exposed to high temperatures these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed.

The pure iron then melts and goes to the bottom of the furnace. The iron ore itself is not pure ore. It is also contaminated with a variety of rock which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason limestone or calcium carbonate is added to the initial furnace charge.
