My ISP offers it, but we are too remotely located. I see no high speed in my future, and am hoping for a change in technology that may change that.Arcani said:no high speed in ur area? that sucks, there is so much out there.
Interesting concept, but one I'd have a hard time accepting. There is more than ample evidence that suggest that craters are caused by collisions with solid bodies of various types. The Spanish gent that concluded the extinction of the dinosaur by impact of a large body with earth is a good example. It is now a well documented and accepted theory.Thunderbolts of the Gods is about a new theory of the universe, they make a good argument, atribute most craters on astrel bodys to giant electric discarge(on melting topic).
You may have noticed by now that I'm not much on anything that goes against logic. Electrical discharge creating the type of damage one would see in huge craters would be an excellent example. Lightning strikes the earth on a regular basis, and leaves virtually no evidence aside from the occasional split tree. I can't begin to imagine the forces involved in moving millions of tons of earth.
This one creates a lot of internal turmoil for me. My objective in almost everything I do in life is to achieve excellence. I don't always succeed, but I do my best to put out quality. That doesn't mean you should share my views, so I'll let you decide which is best for you by presenting some logic.Also i have been striping plated gold electronic components with just salt water and H-peroxide, slow but good to learn on. i was thinking i would just filter the gold clumps out and put the dryed filter right in a crucible and melt down(don't care how pure resulting metel is at this point, not rdy for AP). Is this a good idea or should i put flake aside for now?
There is a ready market for pure gold----local manufacturing jewelers are always in the market for gold of high quality.
Gold that is less than pure must be refined in order to prevent problems in casting or rolling, plus the purity must be known in order to alloy properly.
Bottom line----pure gold is far better to create than gold of questionable quality.
What you've been doing is reclaiming gold, which, in a sense, can be construed as refining in that you are concentrating values. The method you've chosen doesn't yield acceptable purity, which is why I'd suggest that at this point you are not truly refining.
Melting your spoils can complicate future processing, although even that isn't a serious issue. Gold can be poured as flakes, creating increased surface area, making dissolution for refining easier.
Your material, as recovered, is prime for further processing. It is finely divided and lends itself well to an acid wash, then dissolution by various methods, including AR. That would push your quality to acceptable levels, with a minimum of work on your behalf. The choice is yours. If you'd like to have a button of gold to hold, melt some of your spoils as they are recovered. The purity is likely to be fairly good, although below industry standard. If, on the other hand, you plan to raise the quality in the future, I'd suggest storing it as recovered, after rinsing and drying well.
There are many reagents that will precipitate gold-----key is to use one that is selective--so only gold is precipitated. If you don't want to use SMB, you can use copperas (ferrous sulfate), which is generally available in garden shops. Iron sulfate, used as an iron supplement in gardens. It should be light green in color. Brown crystals are not sulfate, and don't work. An ounce of green crystals, dissolved in water with a few drops of HCl added to clarify the solution, will precipitate an ounce of gold.Also, if filtered solution tests poz for gold is there a way to drop it other then SMB?
Urea is not a requirement, for you can always evaporate solutions to expel nitric acid. Urea is used to avoid evaporation. Again, the choice is yours. I never used urea, and wouldn't if I was refining now.does it need Urea?
Depending on the nature of your processing, you may not need urea or evaporation. Steve is the man than can give you advice in that regard.
