how to use mercury to treat gold?

Answer 1

Not to treat gold but to extract gold, they use amalgem to extract tiny bits of gold of rock then they seperate the gold and the amalgem.

Answer 2

Mercury is highly toxic. Back when hats were shined/made with it lots of people wound up going crazy from the mercury on their hat. You never want mercury to touch your skin because of this toxicity. Read the first article.

The process of which you speak is, I believe, called amalgamation. See the second article down at "mining" to see what I'm talking about.

A simple google search of "treating gold with mercury" revealed the third link. ^_^

Answer 3

Your question doesn't make grammatical sense. You generally don't want to apply mercury to your gold jewelry. Hg (mercury) acts as a solvent to gold and silver, and will initially make it appear that your Au or Ag (gold & silver) jewelryis bright and clean. However, it actually disolves the surface. Use a more benign metallic cleaner.

Answer 4

that is a very dangerous process. You can poison your self very easily. My advice is that, if you do not need to, do not do it.
these links should give you enough for an idea, if you need more ask at a prospecting or miners supply. Mercury is nasty stuff.
