refining gold with a propane forge

[Justincase]

I do not think material of such a low content is practical for someone not experienced in ore roasting and Cyanide.
Such material sometimes can be recovered in an industrial setting but is unrealistic for an amateur to pursue.
But do not let that stop you from studying.The subject is fascinating and the size of industrial tanks and ball mills mind blowing.
Where did you get your material from?Is it from your own property or was it sold to you.
Looking at "Fire Assay's" would be interesting and let you look at the process in more depth.
If you are interested in the process all the information on the subject is there for you but it will take you some time to understand,it can not be passed on in bulletin points.
If you find a good deposit and can check the content for yourself then pass it on to a mining firm.
You may even understand how to spot black sand and gold reliably. :lol:

Justin; Thank you very much for the information and guidance. After reviewing all messages and research material i have made a decision. Based on the fact that the ore was given to me by a friend it may be best to use the Aqua Regia to remove any gold in the black sand. The fire assay's is very interesting but too long a process. i have a partial fume hood that can be easily finished . It is attached to an excellent extraction fan. I have a north respirator, gloves and rubber body wear for protection. I need to study the process more and find out where to get the chemicals or acids. my rock crusher is coming along very nicely and will soon be finished. I'm purchasing aluninia cups for the final melt to bars. Also i have almost completed a 4" diameter and 6" long propane forge to use in the final melt. I have looked at your library and found the book needed for study. I can also purchase it for $50.00. i personally like the have a hard copy of the real thing. If you can make any other suggestion , give any other advise, books, videos which can be studied , it will be very much appreciated. I'm always willing to take good experienced advise. i don't like reinventing the wheel. With the time and money currently invested there is no stopping till I have the final product in my hands. Thank you one and all. You have made this 57 year old very happy.
Thank you

Second good lesson,the first was why did I not get any gold from my first attempt.
Because there was hardly any there to start with..
The second will be Why we do not use Aqua Regia for Ore processing.
Fail inevitable survival not guaranteed. cadmium, mercury, lead and arsenic, chromium, cobalt, nickel, selenium, antimony Radium and thallium but to mention a few of the more obvious problems, there is not enough room or time to list all the problem compounds. . If you do not know how to detect and avoid them don't worry too much,just chart their progress by your loss of hair/teeth and slow decay into dementia.
Look forward to hearing your experiences.
:lol:
A fire assay has been found to be the easiest and least time consuming method for assessing the Preciouses metal content of material. It has stood the test of several thousand years.
If you think that is too time consuming you will be disappointed about the time and effort that will go into recovering value from base ore.Not to mention the only leach that works well will kill you dead with just one mistake.
There are no short cut's!
Along with the seven P's the next best rule of thumb would be...What is the longest distance between point (A) and point (B)??.......The Short cut.
