Platinum won't dissolve either. The same with many silicates,
saturated organic fluorides (e.g. PTFE), and some other stuff. That's why
when I suggested this course of action, I said that what doesn't dissolve
"might" be gold.

precious metals plants often have a dual locker system for security ... one
strips off work clothes (which are then laundered in house to recover the PM's)
walks out of the secure locker room through a sensitive metal detector ( with a
cloth robe on for modesty - or to stop showing off in my case :-) ) ... then to
the "insecure" locker room where they get dressed in the clothes they bought
We had no female hourly ... but in the executive side we did have a random
strip search to go with the empty the pockets and pass through the detector ...
and the executive (salaried) female employees had a female security guard to
perform such ... I would jokingly go to her side when I got that red light ...

This is true. It's just that if they're standing in the tub
and having potassium cyanid sprayed on them, one has to assume
that they'll (a) die, (b) fall down, and (c) mess up the measurement.

In which case, detecting gold *on* the body is likely to prove a futile
exercise. Once your employees wise up, they will conceal purloined gold
*in* their body. Cavity searches will not be enough, either. With Au
being inert, the best concealment would be to have swallowed the metal.
While nuggets of gold would show in x-rays, gold dust would disperse in
the stomach contents, so may not be all that conspicuous. Subsequently,
to recover the gold the thief would merely have to improvise a settling
tank at his home, and stir its contents from time to time ...

Can dogs smell gold,
or be trained to recognise it.
If they could have a sniffer dog sniff it out.
Another method may be to have a sting operation to buy the gold back,
and see who is trapped.
Angel, I have been thinking this over, waiting to see what others say about
this. sadly, I have yet to see anyone hit the core of the problem. If they
have, I must have missed it.
It's called trust. If you have a mine that does not have men you can trust, it
doesn't matter how rich the ore is. Eventually the lack of trust will literally
nickle and dime your company to death. There can never be 100% trust and there
can never be 100% honesty. That's life. You just need to make sure the men and
women you have working for you have some kind of reliability.
This can be remedied by hiring managers and supervisors that you KNOW you can
trust. Not everyone is out to get rich at the risk of losing their job.
Managers and supervisors especially. They have the years of experience you need
behind your company and most likely certifications to prove it. If they screw
up at your operation, that will be a heavy burden on them seeking employment
The drillers and the muckers and powder monkeys, they are a different sort. I
have known a few of each, from my own experience in mining, mostly. And I have
met a few that had experience, but you couldn't trust them with much of
anything. By far the biggest cause is alcohol or drugs. Or, they just don't
care. They were carefully weeded out by the supervisors as they had the
know-how to separate the losers from the winners, so to speak.
Yes, it is wise to have some method to make it difficult for miners to "hi
grade" the mine. One I encountered is exactly the opposite of what you want.
You want to prevent it. One mine wanted to promote it.
There the rule was if you found some ore you wanted to keep, show it. So long
as you showed it, odds are you could keep it. In some instances if they likesd
the specimin, they'd offer you some cash for it. Not the market value, of
course, but more like a finders fees. No, if they wanted it and you didn't want
to give it up, you had no choice. After all, the ore and the mine is theirs,
you're just doing the work. That mine, just a handfull of employees, was
successful until the owner had a stroke. Not the only reason, but the biggest.
The theory that worked off of- and as far as I could see, it worked- is that if
the miners get a percentage of the profits, as the ore they took home would be,
the more effort is put into improving the production and quality of ore. And
when a few rich streaks were hit, the guys that hit that streak got a really
Angel, if you can't trust or rely on anyone at your mine, it doesn't matter how
rich that ore is. You must have good competant people working it. Otherwise it
won't mean anything if you have stacks of gold bullion down there ready to be
trucked off. It still has to come out of the mine.
And with that said, I realize that you may not be in mining. I suspect not as a
competant professional mining engineer or a competant professional mine manager
would know these things. But in any industry, the theory holds the same. Trash
is still trash, you can't change that. But when you have good employees, they
are, essentially, the proverbial Golden Goose. In any business you have four
primary concerns- Customers, Product, Employees and Management. All three must
1. If you have a bad product, it doesn't matter if you have good employees,
because the customers will soon go elsewhere.
2. If you have a good product but bad employees, your customers will soon grow
tired of them and again, go elsewhere.
3. If you have a good product and bad management, good employees will be very
hard to come by and therefor you'll have a high turnover rate resulting in #2.
4. If you have a good product, good employees and good managment, customers will
be many. With the exception for market rates. If you have a good product that
depends on the market, you might have a problem. Mining is a really good
In any case a reputation is soon created. Good reputations are what keep
businesses going strong. Bad reputations are hard to fight, and they can be a
serious downthrow to most any company.
No guarentee that will answer your questions, but I hope it helps you somehow.

Particularly when retards such as yourself fail to snip the previous
