Hi Wombat

I think he was saying that if you had looked under Gold and Its Properties Section, you would have found your answer there (about halfway down)

Thanks Jeff. I knew that there was a formula but I could not remember what it was, A couple of mates got 2 nice little specy's yesterday and we what to know the gold content in each.
Thank again

Cheers Wombat

Gold in Quartz calculation

Post  goldnugget on Sat May 29, 2010 9:37 pm

Hi guys,
Not to be picky , but for those interested in a bit more accuracy (if I have my figures right!) I calculated the gold in this example to be 45.25 gms (using pure S.G's.) This was done with Chris Hakes 'stab in the dark' method. The difference is only a bit over 3.3 gms but for some people a 7.3% difference (from the lower weight) may be significant.

Cheers,
Rick.

Hi im new to the site but i think this is what you want
G (gold) = (d x N x (1 - q/n)) / (d - q)

G = Weight of gold (grams)
d = Density of gold (approx. 19 gm/cubic cm)
N = Weight of nugget in air (grams)
q = Density of quartz (approx. 2.6 gm/cubic cm)
n = Density of nugget ( gm/cubic cm)

Density = (weight of nugget in air) / (weight in air) - (weight in
water)

Wombat be careful, pays to check weight of quartz if there is similar material around find as i've known it to vary from 2.4t/m3 to 3.0t/m3plus depending on ferrous and metallic type material with quartz
