How many kilograms of minerals have we "mined" from space?
I imagine most of it is from the Apollo missions, but I could be wrong.

Remember: Pure research has nothing to do with immediate return on investment or predicted findings or efficiency.
And it is an open ended result: micro-grams brought back ..... to tons examined but not moved ...to a few pounds brought back for study.
The total amount .... I wonder.

I would not call any of what has been done "mining". Mining implies an economic motivation, it implies ore recovery for such a purpose. Any geological samples that have been either returned to Earth (from the Moon) or examined in-situ (Mars) have been done for scientific research, not "mining".

to dig in the earth for the purpose of extracting ores, coal, etc.; make a mine.

If you want to know the amount of material returned from the Moon, the amount is easily googled.

360 kilograms was brought back by the Apollo missions and 340 grams by the Russian robotic missions.

"Indeed, scientists are still gleaning new insights about the moon from the more than 800 lbs. (360 kilograms) of lunar rock brought back to Earth by the Apollo astronauts in the late 1960s and early 1970s. For example, recent research has shown that these rocks contain a surprising amount of water, forcing scientists to rethink their ideas about the moon's early days."
