Hello all, I recently came acrossed some gold flakes and I was wondering to get money for them would it be better to leave them alone or to melt them to make a ignot?

Depending on how they look, some jewelers will buy large flakes/small nuggets at a premium for jewelry making. Otherwise, it's probably easiest to melt them into an ingot. That way, you can also purify the gold a bit to raise karat. Also, easier to store than to keep a bunch of small bits in a jar somewhere.

As far as selling, my experience is that refiners will take 3% for the assay costs. If you go through a jeweler (if you have small quantities), then expect about a 10% cut for the jeweler. Those "cash for gold" places are all rip offs who will give you a fraction of spot, and many jewelers go this route too, so before you sell, make sure you know 1) spot price that day for gold (go to kitco.com) 2) exact weight and purity of your gold 3) some idea (as above) what standard cuts for the middleman and refiner are.

Depending on what you've got (purity wise), you may or may not want to use flux. The borax flux you're used to using with forge welding works well, but there are definitely more aggressive smelting fluxes out there that are pretty easily made.

You'll definitely need a crucible of some sort. If you're smelting large quantities of low quality gold (and will need a lot of flux, and a lot of time in liquid form), then a nice flux resistant ceramic or silicon carbide crucible is nice. If you're dealing with smaller quantities, or more pure stuff, a really cool (and inexpensive) route to go is to melt your gold in EDM graphite molds (carve 'em yourself). There's a tutorial on casting in graphite in the tutorial section that you can read.

A torch can be used as the heat source, or you can use your forge. Gas would be easy, if you use coal/coke/charcoal, make sure your crucible of choice can stand the heat/blast of the forge. Last thing you want to do is spill liquid gold...

Here's a post from another forum that kind of gets into using flux to get gold from concentrates:

If you've got more specific questions that you maybe don't want to get into publicly (quantities, type of gold etc...) feel free to pm me.
