This info was lost during recent maintenance, and thank fk someone other than google 'caches' insignificant crap around here :rolleyes:

Here you go frenchy...
The following info will help you figure out your blob of "2.25KG of Industrial Silver, recovered from high powered TV Transmission".

Just do a Density Test buddy, and compare with 10.49 gcm-3... please pretend i wrote up that epistle too cause i dont mind snatching credit cheers.

Simplemons* Test:
1) Weigh suspicious silver
2) Work out some figures:
==> ("Mass of blob" divide by "Mass of blob if 100% pure silver") multiply by 100 and divide by 1.

(a/b)^100/1
*Where a is mass your blob
*Where b is mass of blob if 100% pure silver
**This will work out the percentage of silver in your blob. Simple.

What do we know?
- We know the weight of the suspicious silver (i.e. 2250 grams)
- We know that pure silver weighs 10.49 grams if a perfect cubic centimeter.
- Only you know what the displacement of water is (please see numerous examples online How to do a Density Test if wanting to know more.

*Simplemons is a Trademark of WAFFLE & FLUFF

Can anyone tell me what purity is in Industrial Silver recovered from Hight Powered TV transmission? This use to be for the analog network which are been decommission all over australia.
Looking forwards in everyone answers.

Yours Frenchy.

Of course. You will at least get a rough idea

Are natural silver nuggets normally pure Ag or are there usually other minerals present? If other minerals are present wont that affect the SG calculations?

Natural silver nuggets are never pure silver.
 
simply weigh nugget, then density test (i.e. displace water)...
then compare results with...
a casted 999 (or the closest you can get) silver ingot that matches the volume of displaced water the nugget spewed out (i.e. density test), then you weigh the result to find out

then you can work out...
(a/b)^100/1

a = your nugget weight
b = your casted silver ingot 'weight'
.
 
if you dont like working with Pi just try to use a container with metric measurements (preferably in cm) that is squared (not like typical beakers/cylindrical), then you can easy work out gcm-3
 
Great to learn interesting stuff. SG testing of gold in quartz rock is tricky due to purity (SG) variations in both the gold and quartz. Accurate calculations are difficult to make particularly if the amount of gold is less than 1% of the total weight of the specimen.

This is good info for all members.

I ASK, intelligent, knowledgable persons (such as yourself) answer, other members learn.
