Which skills do I need to control two mining drones?

Also, I’ve been using the button F to make the drone engage in mining, but how do I do this with just my mouse?

I answer that in your other thread.

And third, I forgot to bring my drone back to my ship before leaving an asteroid belt, does that mean I have permanently lost that drone?

It’s possible for other players to scoop it after you have left grid, but you can always try going back to get them. When you land on grid, right click on your capacitor donut and select “reconnect to lost drones”.
