Steve;

It would be far better if the DjVu would be in the 'Allowed Extensions', both in terms of the small file size as well as the print quality.

Google 'DjVu Reader or Viewer' if you don't already have one.

I am sending you the file as an email attachment (offlist).

Shaul,

I already have the deja plugin.

Fine, I sent you the file.

Good Luck with it.

Shaul,

It will be easy enough just to zip the file and then post it.

Gus;

First of all, thanks for your efforts in trying to make this available to everyone.

I don't know what happened between the DjVu file that I sent you and the file that you posted, but there are major printing errors that aren't in my copy.

For example, the title page is supposed to say 'Refining' and not 'Resining'.

Also on pg. 5 3rd paragraph down it says 'on^the ore'. It's supposed to say 'once the ore'. Also the next line in parentheses: 'materraf'. It's supposed to read: 'material'.

There are other errors I've seen as well. I'd hate to have to go through the whole thing, line by line.

Sorry to be so picky but my Father was a printer and proofreader, so the first thing I hone in on are the printing errors.

Let's try this:

Seems to work.

One would still need to download a DjVu viewer plugin from the internet.

Steve, Thanks for the zip tip.

This may be too much to ask but, has anyone scanned the second edition?

 

[istari9]

Thanks I have a hard copy as well but this is a page saver for sure!

I have both editions of CWAmmen. The second edition has additional chapters with maybe a little addition to previous chapters. I just received C.M.Hokes book today and did some reading and browsing. I'm already finding these books very valuable and plan to read them most of the winter before getting into refining.

I also have "THE SECRET TO SUCCESSFUL PROSPECTING Testing, assaying, and identification of GOLD-SILVER-PLATINUM"
By Prospector Ed, Ed Fusch of Riverside,Washington. I have been using this book for a couple of year now and with the help of C.W.Ammen and C.M. Hoke books and this forum I can go slow and add refining of precious metals to the assaying that I have been doing.

I have a lot of appreciation for the information going out on this forum.
Thanks

i know this is an old topic but i just got ammens book in the mail and i think its an awesome book. i found a cat refining technique in here i wanted to ask about.

in ammens book it says you can smelt the honey combs, rods, or pellets with steel, then dissolve it in sulfuric acid leaving the precious metals as insolubles. does anyone have experience with this?

I have no experience with cats, but I'd like to comment on the idea of melting with steel.

Unless you have access to a carbon arc furnace, or an induction furnace, I don't think you'll enjoy much success. Steel melts at a very high temperature, in the vicinity of 3,000° F. The typical home built furnace would be incapable of achieving the temperatures required. Does Ammen make any recommendations for melting methods?

Wow,

Thanks for the upload. That is another fine print, that will consume many hours of my life for the next few weeks.

I love the sketches included, they prove invaluable when the reader gets bewildered.

Thanks Again,
Nick

i understand i wont be able to do this at home, i just found it very interesting.

it does say to smelt it in an electric furnace. does the biscuit get vaporized in the smelting process? what makes it acid soluble if it wasnt already so prior to smelting?

Because I'm not familiar with anything to do with cats aside from having chemically processed some of the ceramic beads, a long time ago, I'm going to have to assume that the biscuit to which you refer is the ceramic part of the cat in question. Correct me if I'm wrong.

An arc or induction furnace can achieve temperature high enough to melt the material in question. It doesn't vaporize, but is melted. Once molten, the steel acts as a collector of the values, which you likely already understand. The lot is given a soak time,which would insure that the values were collected by the included steel, then it is likely poured to a mold of sorts.

The biscuit, which had been melted, goes off as slag, likely having been melted/dissolved along with flux of some kind. If the material was to be poured to a cone mold, separating the resulting button from the waste material wouldn't be much of a chore. That is common practice when working with copper based alloys, so I'm assuming that would be the case with steel.

What makes it acid soluble is that the ceramic material is eliminated. Steel will readily dissolve in dilute sulfuric acid. The furnace process is strictly to collect the values and eliminate the ceramic portion. It does not change it so it becomes amenable to acid processing.

aahhhhhh, that cleared it up fully. thank you once again.

Can anyone tell me what they are using to view the djvu file?

gustavus,

Thanks, I installed the LizardTech viewer and it works great!
