One of my most frequently performed tasks in Photoshop is removing the white background from pure black-and-white grayscales by dragging the gray channel onto the dotted circle option in the channel menu (sorry, away from my laptop at the moment so can't be more precise) which selects all the white pixels allowing me to delete the white pixels in one fell swoop.

Is there an equivalent workflow in Gimp? Thanks!

To select all the white pixels, use the color selector ( ) and click on any white pixel.

But as Rich says, Color-to-alpha may give better results.
