Bases aren't oxidized in air.
they combine with oxygen and form oxides. iron oxidizes into rust (iron III oxide) copper oxidizes, so does aluminum, so do most metals. some metals, such as gold and platinium oxidize to a much lesser extent, keeping them shiny.
Coke is not used to oxidize the slag . It is carbon that is used to oxidize slag.
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.

Pure Iron (Fe) doesn't directly react with water, but it will oxidize (rust), especially if the iron is just wet and is exposed to air a lot. I believe iron will eventually oxidize if kept completely underwater too, but as there is less free Oxygen for it to react with down there, it is a longer process.
there is oxygen in air
Exposure to air caused the apple to oxidize and turn brown. He didn't want the metal to oxidize, so he applied a coat of primer.
the air
Cause the iron to corrose-oxidize-rust.
Silver and copper! both will oxidize noticably.
"After a copper roof is installed, the metal will begin to oxidize and the roof will acquire a greenish patina." "Pure sodium will oxidize rapidly in air, and react explosively with water."
They generally oxidize with exposure to the moisture in air, producing rust.
oxidize/rust, but mostly rust.
Fe2O3 is not going to oxidize further when exposed to humid air. At STP, it is a stable compound.
There are US air bases in a couple of dozen countries.
zax oxidize
It takes 3 hours for a cut apple to oxidize.
