New video section for fire assays of ore

[4metals]

I have just added an excellent video series by Rob Boyko from Youtube. It cn be found at the end of this thread. Feel free to view the series and open up a new discussion thread if you feel you need clarification.

This will be an interesting series to watch. I have a bunch of black sands to assay from the old glacial moraine.

4metals, thank you for a very comprehensive video selection. My only complaint about the fire assay videos, is that the author continually mis spelled the term "gangue".

If that's the worst of it we can surely forgive him. I would also bet we couldn't find 10 people to pronounce the word the same either.

Besides, no matter how pronounced or spelled it is by definition worthless!

Just for posperity, it is pronounced "gang", for people who wonder.

"gang", for people who wonder.

where does the extra "ue" go?

Gangue.

Gangue.

I know where it goes when you spell it, I was wondering where it goes when you pronounce it!

Maybe, in a weird sense, it is understandable that a word which is used to describe the worthless portions of an ore should include a few worthless letters.

One other item I felt would be a nice addition to the well documented videos on fire assaying, is a chart showing the final weight of parted 3-999s Au, and how it represents the final weight, in Troy ounces per ton of ore. Several charts showing the relationship relative to wether .25, .50, 1.0, or more assay ton was used for the fire assay. I can do the math, but easy look up charts are always handy. Also recommendations for the measurement of the bead using a micrometer would be handy. A scale accurate enough to weigh a microgram is very costly.

I never liked those micrometer style devices to
determine assay concentrations. But yes, milligram scales are costly.

By the way, what is the diameter of a 1 mg bead? Immeasurable I would say!

If you subscribe to his channel ask him if he has such a chart and mention you found him
through the gold refining forum.
