What happens:
"Thankfully, the ash that comes out is hot enough so that not every particle is neutral: many are positively charged ions and many are negatively charged ions.
If you can make something push the positive ions differently than it pushes the negative ones, you can create a charge separation! If you get enough charges separated, you can make a large enough voltage to give you lightning!"

Sort of correct, though I have never heard of this, but I'm just a closet science nerd. Also, quote your sources.

Scientists don't know exactly how lightning is created in an ash cloud, however. But they expect it's a result of particles rubbing together, generating friction and electrical charges.
The volcano lightning may be generated in a similar way to that in normal thunderstorms in a process scientists have dubbed "dirty thunderstorms." In a normal thunderstorm, ice particles rub together to generate an electrical charge; in the case of a volcano, rock fragments, ash and ice may all rub together to produce this charge.

Saying I'm wrong is, well, wrong.
It's the same deal as when you rubbed a glass rod with silk in science class.
