I’ve been playing in the mud and dirt for three weeks. I’ve sifted, classified, melted, roasted, and thrown buckets of it in frustration because I found a little gold on our property and I want more.
It’s everywhere but you can’t see it. I think the rock here was infused with tiny particles of it when they were formed rather than in visible quantities in quartz veins. You have to crush the ore and process it to get to the gold.
I think much of the gold is encased in what is called sulfides: a mix of metals and sulfur. These sulfides have to be reduced to iron oxide or rust by roasting in order to release the gold. You then have to smelt it down to separate the gold from any remaining metals.
All of the above factors make recovery difficult and I’m trying to determine if it’s worth the effort. Separating the small particles from the rest of the riffraff is near impossible unless you have the knowledge and the equipment.
To make things even trickier, gold is hydrophobic and small particles tend to be repelled by water. The kind of gold dust we have here floats on water and goes right over the edge of a gold pan so you have to add dish soap or Jet Dry to make it sink so you don’t lose it.
Another option is to take advantage of it’s hydrophobia to separate it from the other materials. Commercially, a process called flotation is used to float the gold to the surface of the water to separate it but for me, my food processor and some dish soap might suffice.
Outside, I have piles of dirt, tools, kitchen utensils, a sluice, a blow torch, and all other manner of weapons strewn about. I tend not to put stuff away in my feverish quest for the precious metal so the place is a mess.
I have yet to build a furnace that will get hot enough to smelt properly so I might have to buy one. I have yet to see much of any gold other than the few flakes that got me started on this hunt. I wonder if I’m wasting my time. If there is any gold, I wonder if it will be worth the effort to recover it.
Regardless, I’ve been bitten by the gold bug so if I don’t find any more here, I’ll just go look somewhere else till I do.
