Is there some reason you cannot pose questions here on the open forum where everyone participating benefits? Or are we evolving from an open forum to a dating site?

I read the introduction post with the 4 questions and didn't think I qualified to post, but if I can speak with a professional as suggested then maybe I can qualify to post.
Every member is allowed to post.
If you post something stupid or wrong you will be corrected.
Nothing worse than that.
Well by the way we do not accept uploads if copyrighted material.
Links to public sources of said material is ok.
If your questions are reasonable and well thought out concerning a future or ongoing project you will absolutely be better off posting here than in private messaging. Not that whomever you PM cannot help you, but because the answers you receive from the forum are cross checked from many different perspectives and poor suggestions are ferreted out.
I say this from a career of consulting in this field (now retired) and a forum member for about 15 years. The information received here from serious questions which are followed up with pertinent details will give you options for either processing yourself or better equipped to interview professional consultants.
Please keep in mind if you start out with an “I have these rocks that I look like they have gold” type questions, most of what I have said above may be ignored! But if you search in the library there are examples of members who benefited greatly from answers received.
Good luck.
Yuo can Look up the Parkes Gold Process. Very succesful process to extract Gold from Lead in Large amounts. Let me know when you find it ?
I know of a Proceedures that has been in use for many years. The good part is that you can reuse the Lead .
I also live in California Maybe we could be of mutual benifit
There is a company called Hindustan Zinc in India That uses the Parkes process ( Patented 1850 ) Just imagine!

When I have small amounts of dirty concentrates containing gold and other metals I melt. Then pour the molten ore into a pan of water which releases' most of the metals that can be panned to collect the gold. The slag that's left is really soft but may contain a small amount of gold and is added to the next milling. I'm only after the gold and this is just another method I use with good results. Large amounts a cone mold is useful to obtain a button of precious metals for more refining. Protective gear should be worn at all times. A video on the method

Is this your video?
This is Omegageek64's video
I can move that in with the other omegageek videos in the video library.
Done, it is now in the video library where you can always find it. If you want to discuss this video in detail start a separate thread and I will link it to the video.

No, it was just a quick search and a bad choice to show corn flaking don't wear shorts.
And the pail of water was a bit small too. I never heard of cardboard to prevent a crucible from sticking, bone ash is used to soak up flux spills on crucible rests and in assay furnaces. Cardboard may work, I just never have seen it used.

I never tried it, but some people say it forms carbon under the crucible and prevents sticking.
Bone ash is a refractory material and works the same. Especially useful to soak up
a flux spill. It is used as a release agent in some molten metal applications as well. But…..everyone has a piece of cardboard lying around, not true with bone ash.
