Argh. Looks like I was rating tonnes as kg.
I think that the way this would work then would be to have the Hector 'nudge' the asteroids towards the processing plant, refuel, nudge another one, etc.
It could still jump with 6,000 m3, but this would take the form of wraping the asteroid, nudging it in the right direction, refuling, catching up to the asteroid, attaching the ship to the ACT, and then jumping. Once at the destination the Hector would need to either re-nudge the asteroid in the desired direction, or call for pickup, or whatever.
I'll have to do some recalculations once I am back at my computer. Anyone able to provide any details on asteroid refuling?

7.9 grams per cm3 equated to 7900 kg (or 7.9 tonnes) per cubic meter

Oooops
I think I did my calculations wrong, then.
I was thiking (for the more dense material) of 7.9 grams per cm3 being equal
to 7.9 kg per 10 m3.
(Just multiplying each by 1,000)
But I think I did the basic math wrong. Let me try that again.
7.9 grams * 1000 = 7900 grams = 7.9 kg
1 cm3 * 1000 = 10 m3
Wait, what am I missing?

Far Trader is mostly right. When it comes to materials, asteroids are
generally either rocky or metallic, so you'd expect density to be about 3300
kg/m³ for the rockies or about 7900 kg/m³ for the metallics.
However, a lot of asteroids seem to be "porous" in that they have lots of
spaces inside them, probably because they are actually "rubble piles" - lots
of smaller bodies held together by their very low gravity and covered in a
surface layer of dust. This 'porosity' decreases the density significantly,
pushing it down to as low as 1300 kg/m³ for a porous rocky asteroid. Ice can
lower the density too, but if an asteroid contains a lot of ice then it's
probably better to call it a cometary body.
