'' Request for Expert Commentary on Red Ore ''

[RogerBack33]

Hello everyone, good forum, have a good day. I am new to the forum but I have been dealing with ore processing for 1 year.

During this one year of failure, I thought I knew something about certain subjects. Until I met this site yesterday.

(By the way, sorry for my bad English. I'm communicating with you using translation.)

I spend my hours studying the topics on the site. I'm thinking of reading Hoke's book too.

I've witnessed many levels of respectful and helpful discussion.

I would like to stay here and exchange ideas with you valuable users and be a part of your family. Thank you for your comments and help.

As for the help topic, I put some examples in the photo section.

How should I process these ores? What preprocessing does it require? How can we achieve minimum time increase and maximum gain?

I can get confused very quickly, I would appreciate if you explain it simply.

I expect your support from all ore kings. Thank you...

Welcome to us.

Please do not use all bold or all caps in text.
It is considered shouting and is considered impolite.

Most of the time an assay is needed if one suspect values in the ore.
It is next to impossible to say if an ore contain values on pictures alone.

Anyway it seems you are on a good way,
Before using any chemical on ores have a proper assay done, so you know it don't contain toxic elements.

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: Screen Readable Copy of Hoke's Book
2. Then read the safety section of the forum: Safety
3. And then read about "Dealing with waste" in the forum: Dealing with Waste

Suggested reading: The Library

My guess: copper ore, also iron

 

[goldshark]

A good way to start, is with an ICP analysis. It will break down into percentages or PPM of all elements present. I would not typically have this performed on the last four pictures, as they are vesicular Basalt, and generally do not contain much in metals. However, there can be exceptions, but don't see much in the way of mineralization, except for possibly the black on pictures 1 and 3. Picture 6 looks like it could be more Siliceous then the other last four, but really can offer no opinion on any potential values.

I didn't know the rules, I corrected the post. Thank you for the warning

I analyzed the stones with a microscope. Apparently there is gold. My question is: What pre-treatment do I need to apply to these stones?

Get a fire assay. This will tell you what the quantity of Au is for a ton of the material.Then you can decide if it is economical to extract it.

I have the necessary equipment to test it chemically. What steps should I follow to chemically purify it? Is it nitric acid or sulfuric acid or something?

 

[RogerBack33]

Yes, I think it contains copper and iron.

 

[RogerBack33]

There are many people in the forum, I expect comments from everyone, but not many answers.

 

[goldshark]

Crush to 100 mesh, pan, collect concentrates, then start refining process. Putting rock into acid will do no good, and may generate toxic waste and gasses. Read multitude of threads on treatments.

 

[goldshark]

Read threads relative to what you are doing under the testing, assaying, and identification section of forum. All has been covered.

 

[Alondro]

It looks very bubbly, similar to iron-rich basalts very common in volcanic plugs.

This samples look interesting from a geology perspective - not so much as ore - but you never know. Since you think you see gold there are 2 reliable, safe, easy tests you can try.

First test: put a sharp point on one of the gold specs and apply pressure. If the gold speck cracks/fractures/etc you can be sure it is not gold. If it bends/dents/etc there's a good chance it is gold.

Second test: since you can see gold specks, just reduce a sample (using any means available to you - even just a hammer) to powder. Then pan it (many videos on youtube) a drop of detergent in the water is a good idea - Jet Dry is preferred. I expect the gold specks you see are some form of pyrite (iron sulfide - fool's gold), or possibly mica. Mica will quickly wash out of your pan, pyrite will follow, along with most other material, except for the "black sand" heavies that collect in the bottom of your pan along with any gold present.

Very good advice You receive
follow what they told You to do.
they really know what they are telling You
and first and the most important is.

Always Safety first.

always use a respirator when crushing any ore
No matter what inoffensive looks like.

Using chemicals is a serious business
don’t use any chemical if you don’t know what you dealing with
many fumes can kill you or disable you in ways many ways.

Follow their advice they know what they are telling You.

If I where You i will stick with the 3rd one

and for Us small miners,if don’t have free mills gold is not worthy all the work and the money we put it in and the time we spend.

crush the rock,panned if You find gold
then You can find a good process
to get the gold out.

that’s exactly what many small and medium miner do.

in my own experience I try many ways
and dealing with low grade ore is a pain
and wasting of Money
and dealing with all the waste chemical
is big wasting of money.

I will stick with free mills gold if I can find it

I’m wasting lot of resources and time.
dealing with low grade that are Not free mills gold.

I learn my lesson.
I will do like the old timer do
If it is Not free mills gold,Is Not for me

I hope You don’t do the mistake like many of Us small miner do
in our quest for Knowledge

read the book of Hoke’s ,the Forum have a for free.

is very informative and will open our eyes to a new world of knowledge

and My friend
common sense and always safety first.

 

[RogerBack33]

Thank you all for your comments.
Where should I send this ore for analysis?

 

[Yggdrasil]

Thank you all for your comments.

Since you are in Turkey I really do not know.
There are some Turkish members here that may know though.

 

[RogerBack33]

Got it, thanks again

 

[goldshark]

www.alsglobal.com is the biggest worldwide research company. Check their website for a lab nearest you. There are probably some smaller labs, but you will have to search for them.

I really got into the e-waste thing a couple years ago. It is fun, and I was able to refine to .999 purity, which was a proud moment. But, those chemicals are just way too scary.

I’m going to stick with free gold. If it needs to be leached out-I’m out
