No, he means "cemented carbide", which is made of Tungsten Carbide (WC) and cobalt. Carbide is tough to find because it is pretty much the most expensive tool metal you can buy. I deal in it, only when I know I can make out pretty good. I will buy small amounts for about $3-$5 per pound, currently. Whatever I accumulate over the course of the year (usually between 10-50 pounds) I sell to a bigger yard about 40 miles from my house, and they pay about $10 per pound currently (I think). I guess I could mail them there, but I just don't trust anybody that much to just send it away in a package with my fingers crossed. (like those cash4gold scams.)
I actually don't care to deal with it too much. Anybody who is selling carbide, usually won't sell it for less then scrap value... And anybody who has just a little bit of it, will just toss it in the trash, cause it's only a couple dollars to them. It does kill me to think of all of the teeny, tiny carbide inserts that must get thrown out every day (on things like saw blades). Just a hand full of them would weigh about 5 pounds or so, and be worth $50.

scrapping carbide tools.
