Interesting article. :89:

Less tonage for an ounce of Gold?

There is only so much Gold in any given ore.

If it ain't there, you can't get it. :nono:

Correct me if I'm wrong,...

As I remember, been a while since my geology and mining/assay classes,

cyanide disapates over time when exposed to the atmosphere.

It dies, leaving the solution non-toxic. :idunno:

 

The mountains of leach fields in N. Nev. are completely safe after processing.

There are no mounds of toxic waste left behind. :nutty:


G-pa made me do it, he gave me my first "Steel" pan.

This is what I was told in class,...

 

(From pg. 22, Cyanide Uncertainties)

 

"Mining and regulatory documents often state that cyanide in water rapidly breaks down—in the

presence of sunlight—into largely harmless substances, such as carbon dioxide and nitrate or

ammonia."

 

Apparently I was mis-informed.

Thanks for clearing up the issue for me, Elder. :shake2:

A few times in my life, I became seriously ill for no know reason.

Turns out, blood work turned up some crap I was working with that was slowly poisoning me.

 

It was something in my work environment.

 

Have seem cases of mercury poisoning & other chemical poisoning that left the affected person looking like someone threw acid on his head.

 

Always read the MSDS sheet on any chem you are around, or working with.

 

Asbestos contaminated vermiculite mining killed a whole lot of people in Montana > http://www.nytimes.com/2009/02/19/us/19asbestos.html?pagewanted=all&_r=0 <.

 

Always protect yourself, because sometimes employers will not.

A little bleach (sodium hypochlorite) make cyanide harmless also,no big deal as one of the safest ways to heap leach ores and reclaimation relatively ez too.Never used cornstarch but still reading up on new twist- John

In the late 1970's worked on the first modern leeching system in California near Glamis. Helped Canadians Chester Millar and his son Mike. They went on setting up their leeching system in South America, Mexico, Canada, US. They are both dead now, Mike died in his middle 40,s and Chester died in his late 60's. Chester was entered into the Canadian Miners Hall Of Fame. Cyanide accumalates in your body and kills you over time. Am glad I turned down their offer to partner with them, but sad that they died at such an young age.

A far greater health threat in open pit heap leach mining  is the release of mercury.

 

 

Wet/Dry said,

 

"Cyanide accumulates in your body and kills you over time" this statement is not accurate.

 

I should be dead then after all the years as a ADR operator. Fact is the chemical is absorbed into the blood where it encapsulates the oxygen cells then it metabolizes.

I seem to recall reading something about everytime we take a breath, we exhale a tiny volume of cynide gas. The greenies would have the human race banned if they found that out. :th_panic:

Keep in mind aqua regia, nitric & sulfuric acid are not child’s toys.

You seriously pay for mistakes fumbling around with any of those.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAmen. Cyanide doesn't accumulate it just flat out kills ya ,hence the gas chamber. Mercury is the king of accululation in your liver and tissues BUT chelation therapy executed extremely carefully does work for metals/toxins removal. In Costa Mesa back in the early/mid 80s there was the Institute of Chelation Therapy of CM and did a stint myself. Nothing but EDTA titrations ,extreme diet,and lots and lots of blood tests BUT them liver biopsies are a BYATCH. John
