Dry pigment will always rub off very easily which is not suitable for wargaming minis. If the pigment is flowing when fixer is applied, it means that you're effectively making a wash. How you apply pigments varies entirely upon the effect that you want to achieve. You can use white spirit, pigment fixer, alcohol, distilled water, and probably other things to secure it to the surface. Again, your choice will depend on the desired effect.
It sounds like you're trying to get an even coating of dust over a flat surface. In that case, mix some pigment with white spirit and apply over the surface. If it flows, you're using too much. You can also apply the pigment dry and dab a brush that's damp with white spirit near the pigments so that it gently flows through the pigments without actually moving them. I would also try the same effect with your fixer.
Google "apply pigment scale model" and you'll get tons of information including youtube videos. Find a tutorial that matches your desired outcome and do some experimenting.
It's also worth mentioning that your problem could be that you're trying to apply pigment over gloss varnish. Pigments can be applied directly on to paint or on top of matte & satin varnishes. Again, you'll need to experiment to see what works for your particular project.
