[The Mist] How exactly did the Government get rid of The Mist?

It just seems to disperse whenever the Military are close by. I thought that the flamethrowers might play a part in it but the army tanks advance without any localized flame throwers.

I figured they must have closed the door or portal to whatever dimension or world the creatures and mist were coming from.  With it closed off, the mist would naturally dissipate, the military was just advancing against the vanishing mist and destroying whatever creatures and infestations they came across.

But I've only seen the movie and the book may paint a clearer picture.
