Lesson 6 - Processing Test Results and Analysis - Technical Level: Expert

[@AnthonyJacobsMusic]

I feel your pain. This video made me realize that gold prospecting might be as much of a pipe dream as crypto mining-albeit crypto mining is less work. Hang in there. :(. Your pocket is out there somewhere.

So, in an earlier life, i was taught that one needs to screen fire assay results of lode samples over an ounce per ton, take a look at the ore mineralogy and amount of free gold present, and, finally, run column tests on the various particle sizes of ore to see if you can get the gold out or not. Just a consideration for your viewers. I like the way you analyze the results of your final tests. I think there is a recovery issue with the ore in the mineralogy. Perhaps it is a distribution of the particle size of free gold issue? Need additional data... Is gold tied up in sulfides or quartz, or in the alteration? Does the ore need roasting? If so, walk away. Thanks for this discussion.

In this case it is fully oxidized. Yes, the preliminary metallurgical testing is more complex than most people realize. You can simplify to some extent, but only at the expense of increasing risk.

Thanks again! This is all very interesting to me.

[@garylawlor2288]

These are great videos 👍

[@hardrockuniversity7283]

Thank you

[@lifetillend7448]

Great work

[@hardrockuniversity7283]

Thank you

[@cristianmartanov4736]

Thank u for all the shared information .to have more succesfull videos work on a good thumbnail and an intresting title

[@hardrockuniversity7283]

I'm getting better at it, but it is quite a learning process. Thank you for the advice. keith

[@sams7967]

Very informative video, where do you send your samples for assay? I am in AZ . Looking forward to the next lesson, Thank you

[@hardrockuniversity7283]

Sorry for the delay in answering. I never got a notification on this.\ I am currrently using Chris Christopherson Inc. 123 E. Main St Smelterville, ID 83868 Phone [phone] Fax [phone] Keith

I like your music

and how does the refinery relate to tailings from the gold rock?

[@hardrockuniversity7283]

By calculation how much one recovers and how much one loses with different techniques that cost different amounts, one can determine what is the most profitable way to process the ore.

YeeeeeeHaaaaaa

good morning, I wonder if I understand Class # 6, are recovered 72.1 g ie 0.0721 fk black sand concentrate high grade on a sample of 200 pounds or 90.72 kg is? thanks

[@DeliciousDeBlair]

Can you dissolve the fines economically? Like with a CN leach? ~( 'w')/

[@ghlscitel6714]

To disclose a secret to you: The NIST and with it the whole US of A is in meter, kilograms and seconds (MKS system) since more than 70 years.

Show me the dirt. Show me the rock.

Look at more recent videos. :-)

[@johnnyllooddte3415]

what was the results.. was it worthwhile or not.. i wasted 7 videos and you didnt say anything of whether your results were worthwhile...geeesh.. doc johnny

[@hardrockuniversity7283]

That would be in 'Can I make money gold mining'. The short answer is no for this project. It only ran about 1/4 Oz/Ton about ten inches wide. Between the low grade and low tonnage it would not be possible to turn a decent profit. It takes all these steps just to get to the calculation point. It is not as simple as one would want If you go to my web site HardRockU.com I have made a mining project economics calculator that lets you input the numbers for any proposed project and get a good idea whether it makes sense on paper. Ball park: for an underground mine with no complications you would generally want at least one ounce per ton, one foot wide or 1/2 OZT two feet wide. For micro scale ( one or two tons per day)it is hard to make a profit on 1/4 OZT, but for larger throughput, it gets VERY profitable. Keith

good morning, I wonder if I understand Class # 6, are recovered 72.1 grs ,0.0721 kg,of black sand concentrate high grade on a sample of 200 pounds or 90.72 kg is? thanks

[@hardrockuniversity7283]

No, it was 8.6 Kg (18.95 lbs) of black sand concentrate that contained 72.1g of gold / 1000Kg of concentrate. That worked out to only 34% of the total gold in the original sample. With 30% of the gold in the original sample recovered as free gold, that meant we only got 64% total recovery in this test. That is not very good, but not terrible. Keith

[@nouguesjuan5164]

it is not necessary to pass the rock ground by a primary hub first horizontal centrifuge, before passing through the floatation table ??? and after the floatation table it is necessary to review the gold concentrate and a secondary micro centrifuge multihelix espiral.-What is sequence of processes for gold recovery in crushed rock? I work a mineral of 20 grams per ton, about 20 tons per day partida. rock-team recommends that me and that amount should concentrate obtener.-AS PROCESA CONCENTRATE OR LEAVING BLACK SAND TABLE O CENTRIFUGA, I am ARGENTINA AND WOULD LIKE TO SELL THIS CONCETRADO, THAT YOU CAN TELL ME, SOME REFINERY ???

[@hardrockuniversity7283]

Mine is a gravity separation table- not floatation. I am not familiar with refiners in Argentina. I would suggest talking to mining companies or assay labs to see if you can find one. Keith

[@nouguesjuan5164]

Good morning, thank you, I have a question, is regarding the installation of centrifuges FIRST AND SECOND GRADE TYPE HELIX MANUFACTURED BY GOLD-INDUSTRIES, THEY DO NOT INCLUDE IN THE PROCESS OF RECOVERY OF GOLD ROCK GROUND TO TABLE floatation UD is your opinion? SECOND QUESTION IS THAT PROCESS MAKES A BLACK SAND RECOVERED IN THE PROCESS before sending it to the refinery? IN ARGENTINA NO REFINERIES PROCESS, YOU CAN TELL ME SOME REFINERY IN USA, MEXICO, ETC?
