Good reply by Jim Franklin. I will add that there will be probably no "miners" on the moon. The mining industry will be highly automated because of the cost of using human labor on the Moon, and also because robotics progress every day. And if some dust is disturbed upon the surface and some bright patches appear.
Thanks, however, we will still need humans on the Moon to both manufacture and maintain the equipment, our technology does not yet afford us the ability to have a single machine lofted to the Moon that then runs off and makes a load of autonomous machines of all types, including for maintenance, from local materials.
The Moon has all the materials we need to make everything we have here on Earth, but it lacks the complex infrastructure that has take well over 100 years to create to be able to mine, process and manufacture raw materials that can then be used to make useable products.
1 metric ton of Iron requires an estimated 153MJ of energy for it to be mined, transported and smelted, even with efficiency savings, that figure will not change markedy as the laws of physics and chemistry are the same on the Moon as they are on Earth.
Basalt samples from the Moon show the average mare basalt sample is only about 8% ilmenite by volume, and ilmenite is only 36.81% iron by weight, thus, to produce 1 metric ton of Iron would would need to process around 1600 metric tons of lunar regolith.
Thus, we would need heavy machinery, controlled by humans. Yes, these ore processes would not need to mine in the conventional sense here on Earth, the surface of the Moon is covered in regolith, but the ilmenite content and the Iron content of the ilmenite will vary across the Moon just as ore concentration varies with location on Earth.
