Python Image segementation and extraction

I am trying to figure out how to extract multiple objects from a greyscale image with mineral grains. I need to segment the different grains and then extract each of them to save as a separate image file. While doing research, I have found that everyone uses skimage.

Has anyone had to work on a similar problem?
