Need an assayer

[Martijn]

Secracy was not about forum, though every one know here are many secrets too. Many refineries/ refiners not share process until they not find a more suitable process for same purpose.

There are two rules to succes!
1; never tell everything you know.

As Goldshark say.
It may be beneficial to learn how to do some simple assays yourself.
Then you will not need to send something to a lab that has no values in it anyway.
Unless you are looking for other non PM values.
The books:
Introduction to Torch Assaying by Charles L. Butler and
A textbook of fire assaying by Edward E. Bugbee should be accessible as PDFs online.
This will teach you to do simple assays to get an idea of the content.

Thanks for books. But these are a hobby type trails. Or just to try luck. as i think ,Most of ores, simple in process, are been already finished or running already on scales, i will like someone related to geology to say me wrong or right but most of ores now are out of renge if simple to advance tests.
Smelting with iron was choose after the trails to be noted as most suitable collecter , every time general rules are not applied on every ore

I will like to have 2nd one..!!!

me too

The novel processes used by the big boys may be slightly different than what we discuss here, to protect their monopoly, which is their good right.

arsenic rich sulfides, acidic in nature. Smelt need alot of basic flux that is not economically suitable.
Floatation is easy but still a huge weight is in concentrwte. Not proper labs to test and further decide the depresents.

Arsenic rich sulfides.
that’s one thing i will never touch.

no matters how rich is the ore.

because processing Arsenopyrite is lot of work and lot of equipment.
if it is Arsenopyrite.

lot of safety measure in place.

You are right ,miners always keep their secret.
I will never revealed my thing,only what is already available in the internet.

An alkline oxidation is a good procedure, but right after that cy leaches are fail to recover values,
Re balancing ph after oxidation and smelting is under review.

 

[DaniH]

Any assayer in dubai will be acceptable

What do you mean by CY?
Cyanide?
Then please use the full name or chemical composition.
CN is acceptable since the Carbon and Nitrogen is what makes it a Cyanide compound.

Its already been on production scale, but half of material behave diffrently, might be on basis of its chamistry or whatever happening in smelt.
I am on it for to check what happens in half smelts that not allow values to drop.

The half smelts are most likely due to the matte layer. This matte layer is caused by not properly fluxing the ore. Iron or steel is added to the melt, drawing the sulphur away from the concentrated ore, removed prior to pouring into conical mold. This step of removing sulphur can also be accomplished with the addition of an oxidizer to flux, or by roasting, prior to smelting/assaying, in the open air at around 800 F (slight cherry red concentrate color). If you ore does contain Arsenopyrite, the fumes will be toxic to deadly while roasting. I do not know how to scrub Arsenic fumes while roasting.
There are quite a few videos on roasting on Youtube. Mount Baker Mining and Metals has some decent videos. He also covers the smelting process.

I think some confusion is there

Yes it was my mistake, yesterday i was on mistake most of time. Its CN

 

[galenrog]

Not a problem. Translations can sometimes be an issue.

Also, refiners sometimes appear to be speaking another language.

Time for more coffee.

With respect

the roasting process of Arsenopyrite
is way complicate it.
and Very very dangerous.
Arsenic is poison,and very deadly.

Please don’t roasting Arsenopyrite is deadly and will kill You.

in low concentration will destroy Your body from inside out .

with respect roasting Arsenopyrite is a deadly idea.

big company avoiding dealing with Arsenopyrite
to work with Arsenopyrite ore
they have to spend lot of money in equipments,PPE,training their employee

because any little mistake can be Your last.

Here in Arizona there is plenty of abandoned mine with huge minerals very rich in gold and silver ,but contains lot of arsenic in it ore.
and No one want to touched.

a big company grab one of those mines.
they constructed a huge building and other thing
and in just 2 years abandoned
because no one want to work for them.

Arsenic is too dangerous,is not worthy to risk your life for any amount of gold or money.

is like the oil rig,drilling in the oilfield is dangerous
the H2S gas is dangerous and in high concentration can explode.

please don’t do that huge mistake of roasting Arsenic rich ore
no matters how rich it is.

 

[minero74]

With respect
i hope You guys understand the dangerous nature of the Arsenic.

old miners understand that and they avoid
mine with arsenic.

 

[Vesta Minerals Inc]

You can use the assay lab in Las Vegas, Nevada, Vesta Minerals, they will do analyzes on this type of ore.

 

[DaniH]

Though it is roasted with all possible precautions and in very small scale, but yes, its deadly and cancegonic.
Thats why i was looking some of its process that are much safer, at least avoid roasting.

Removing arsenic from arsenopyrite ore
is way complicate it ,You will need lot of equipments
that’s mean investing lot of $$$$
and probably wont get much in return.

perhaps You can find other methods
that don’t use the roasting process.

but here in the USA,i guess wont find it any where.

government regulation,permits ,inspection
and many other thing.

for that many miners go the the easier ore

for me I only focus in gold,silver,sometime in copper when i’m bored.

is some how easier,less complicate it
and way less toxic that dealing with Arsenic.

 

[minero74]

Close by there is a old mine
that it is rich with lot of Galena but i don’t touch it.
why because is toxic,it contains lead
the dust to inhale or ingest
can cause lot of health problems.

i don’t like lead,when i do smelting (not doing it now).
never used lead as collector.

because when the cupellation process
lot of lead fumes is release it
and is way toxic

i hear many miner have died of cancer
now is known that is because the lead fumes they inhaled
in the process of cupellation.

 

[minero74]

I have prospecting i an abandoned mine.

,nearby of one of Jeff williams claims.
i personally have been in that claim
passing by .
looking for that abandoned mine and we found Jeff williams claim by mistake.

(I will never going to reveal the location of Jeff claim).

that distric is known for some mine have Wulfenite.
is lead molybdate mineral.

few miles north,we found the exact location of the abandoned mine
crushed some ore,panned and
because the presence of lead,we left for good.

i will show You pictures of Wulfenite.

it can fool any one thinking
Oh i get rich .

but when put it under microscope
it’s look like cristal of some kind.

There is no free au. its bounded, microscopic.
