Where do u sell it after u have everything u need to show everything is in order ..who do I contact..
 

I’m actually building a sand collector currently. Basically a large funnel with a valve and motor to shake everything. Hoping to concentrate the heavies to the bottom and then crack the valve to let them out the bottom. I’m in Ohio, we have tons of black sands, lots of super fine gold, silver and some other bright silver flakes, not sure what they are. I figured I’d get a fair amount, roast them and then smelt them. It’s worth a shot!

I'm sceptical of the vibration idea. Hook a water supply to the outlet of the funnel. You can regulate the water flow and create a fluid bed of sorts to concentrate the black sands, gold, etc. in the neck and a small area above it. Classifying all feed to like sizes will make the process most efficient.

Good luck.

I agree. I do have plans to build u trap in place. Allowing me to add water from the bottom. Less vibration and more a side to side shearing motion, like from a motor with a of center plate mounted to the frame of the unit and the vessel. Should in theory act like the stratification action of a pan. I plan to weld some studs inside the vessel as well, something the material has to work around to avoid clumping.

Thanks for the suggestion.
 

A small hand held microscope will help you see a fair bit of what’s locked up in those sands. It’s pretty crazy what you miss with the naked eye. I keep all my black sands so I can trip over the buckets and tell myself I’m an idiot for not doing something with it already.

It’s hard to see anything with those things!
 

Our black sand / red sands concentrate when dry get a trip through the chain mill. Then washed on a ribbed micro sluice or blue bowled with mercury. The Mercury is recovered and the concentrates from the catch bucket are melted and corn flaked. Then we pan the slag collect the gold and dump the slag into our next run of ore. It's surprising how much micro gold is in the black sand is it worth the effort? maybe not but I'll take all the gold I can find. Some days we are shocked by how much gold we recover from a small amount of cons. And then the amalgam ball into the retort.

As of May 2024, heavy mineral sand prices were relatively strong compared to historic levels, with prices for rutile, ilmenite, and zircon as follows:

Rutile: Around US\$1,500/t

Ilmenite: Around US\$270/t

Zircon: Around US\$1,700/t

Premium zircon: Around US\$2,000/t

The global mineral sand market is projected to reach USD 55.13 billion by 2030, with a compound annual growth rate (CAGR) of 2.6% from 2023.
