And in Conclusion......Top 3 Gold Pans!
Dan Hurd has done an excellent job in my opinion of testing these different gold pans, this is a great lead in for panning and prospecting and I highly recommend you give him a subscribe and a bell as his videos are always educational and fun :-)
Have a great day All :-)

Urban Mining In Your Home
I found an interesting article entitled
Below is an excerpt that I found interesting, might have to look into how to reclaim Cobalt :-)
From one tonne of mobile phone batteries, Umicore claims it can extract between 135-240kg of cobalt, depending on the generation of phone – modern smartphones have more. They say they can also reclaim 70kg of copper and 15kg of lithium from the same handsets. Even once the battery has been removed, the electronics inside a phone can surrender around 1kg of silver and 235g of gold per tonne of devices. This compares very favourably to primary mining, which only averages 100g of silver in each tonne of mined ore, and 2-5g of gold per tonne of ore.

How To Recover Gold From Computer Scrap with Household Chemicals
Please remember that RECOVERY and REFINING are two totally different processes.
With escrap, and with many other forms of gold scrap, the gold must first be RECOVERED from the scrap before it can be REFINED to high purity gold.
In this video, RECOVERY is the process of separating the gold from the circuit card material that the gold foils cling to.
SREETIPS used hydrochloric acid and hydrogen peroxide with an aquarium bubbler to RECOVER the gold foils so that those foils could be REFINED in later steps.
After the gold foils were lifted from the circuit card fingers by the action of the the air bubbling through the hydrochloric acid and over-the-counter 3% hydrogen peroxide, I collected all the foils in coffee filters - at this point the RECOVERY process is complete.
Now SREETIPS proceeded to the REFINING of the RECOVERED gold foils.
REFINING is the process of
1) dissolving the gold foils
2) filtering out insoluble material
3) then reconstituting the gold out of solution with a chemical precipitant.
In this video SREETIPS used sodium metabisulfite. Sodium metabisulfite, when mixed with the chloroauric acid (dissolved gold) produces sulfur dioxide gas. The gold atoms in the chloroauric acid have an affinity for the sulfur atoms in the gas and they begin to cling to the sulfur atoms, but they don't bond chemically. At some point the gold gets too heavy and falls (precipitates) out of solution.
When this happens then the REFINING process is complete.
Have a great day .

Reasons why "Urban Mining" rocks.
What is Urban Mining?
The electronics industry is now competitive with both the religious world and the jeweler for gold. It takes only forty cell phones to use up one gram of the stuff. But, it takes a ton of mined ore to produce that gram.
“Urban mining” is the picking of valuable minerals and metals out of discarded electronics. Though recycling is only beginning to catch on in many places, a metric ton of recycled laptop circuit boards can yield 40 to 800 times as much gold as the ore.
For every 1 million cell phones that are recycled, the following amounts of precious metals can be recovered:
16,000 kg of copper
350 kg of silver
34 kg of gold
15 kg of palladium
Benedette Cuffari, “Extracting Gold from E-Waste” at AZO Cleantech (October 26 2017)
Currently, we use heat to burn out the metals, or chemicals to leach out the metals, both are effective but toxic. A company in America has developed a method using water with some additives, and electrolysis to separate valuable metals. It will be interesting if this process becomes public, urban miming might just take off... :-)
If anyone knows of any other methods, I'd love to hear about it in the comments section below. Have a great day :-)
