I contacted Munton's for info regarding their DME. I use their x-tra light DME in most of my brews and now that I am playing with the water minerals, I figured it would be good to know what was already in the ingredients I use.
As a public forum, I figured it would be helpful to post the response I got back.
To use this info (focusing only on Mg, Ca, and Na) - let's say I use 3lbs (~6.6 kg) of their DME in a batch. This would mean that I am adding 2.3-4.6 grams of Mg, 1.0-2.6 grams of Ca, and 1.3-4.0 grams of Na. I would then factor that into my batch volume to find out my final beer chemistry. Right?
EDIT: just realized there is no info concerning Cl or SO4, which would be nice to know. I'll contact them again to see if I can get those numbers.

Please find attached the trace element analysis we quote for our Spraymalt products. Note that this is historical data which is now several years old - so use them as an indication only. To be honest, we rarely get asked for trace element data, and hence we don't regularly update this.
Trace Elements:
Figures expressed in ppm (mg/kg) dry weight
Fe 0.5 - 3.5
Mn 0.5 - 2.5
Cu 0.5 - 3.5
Zn 0.5 - 3.0
Mg 350 - 700
Ca 150 - 400
Na 200 - 600
K 3500 - 7000
