Anything that followed the silver when it was cemented, I'm quite comfortable, was removed by fluxing, and if not, it was separated in the silver cell. Bottom line here is that tin contaminated silver can be successfully processed, but you must do some work prior to digesting, otherwise you may be stuck with one hell of a mess. Harold
To remove chlorides from your homemade nitric you can use silver nitrate, precipitating the chlorides as AgCl Silver ions and the ions of chloride will form an insoluble precipitant a white cloud or puffballs, it can form a fluffy precipitant that can take time to settle if undisturbed, as it likes to float around in even a slightly moving ...
Hi, I know that nitric acid and distilled water solution can be used to dissolve silver and palladium. And sodium nitrate is used to make aqua regia which will be used to dissolve gold. What can one do if one only has sodium nitrate? Can it be used to dissolve silver and palladium instead of...

Listen to Dean he certainly knows his leaching and the do,s and don't,s. Understanding the chemistry of leaching is fine but the real problems arise when you have gold over various base metals and with differences in plating thicknesses, in mining usually you have very low concentrations of cyanide but used in huge volume, with little …

I used some of my refined silver from electrolysis to make a silver/gold chess piece set. The silver is .9999 pure silver but the "gold" pieces are made from aluminum bronze (90% Cu, 10% Al). I used the lost-wax method to cast these pieces from a set of House of Staunton chess pieces of the type used in the Spasky-Fisher Chess …
Hello Yggdrasil, I Will run with following materials: E- Waste as smartphones, computers, and appliances, so generally in electronics boards.

Silver cell: I only need about 100g of silver in a week. I plan to use a 500ml beaker with SS304 cathode. The anode bag will be from a grocery bag. The silver will be in shots (copper cemented silver from inquartation wastes). If I use 90g/L as the electrolyte with 50% distilled water and 50%...

With the Silver Chloride (AgCl) method, Silver can be refined in a batch-wise process to a very high degree of purity (999-9999) with relatively "simple tools" and easy to source chemicals. A disadvantage of this …
Classically inquartation calculations were based on the ratio of silver to gold in a sample after cupellation. cupellation being an assay function where the sample, the added silver, and lead are melted in a furnace and the cupel (usually made of bone ash) absorbs the lead and the base metal leaving only gold and silver. The gold and silver ...
It keeps them honest which is the biggest problem with processors. Unless you know what to expect they will short you. Going to large processors will allow you to capture everything Gold Silver Palladium Platinum Copper etc. On 15k pounds of board I average 47 to 50 OZ of pure gold and about 400 oz of pure silver plus the other metals.

All of the solvent and washing was captured into a "silver stock pot" which is where I stored the used silver coils. The silver powder was dried overnight in a "Little Dipper" crock pot. 4.) Melting and pouring (brand new to me) the silver powder to ingots and cornflake for a silver cell was challenging.

Usually the process for converting silver chloride is used when refining Silver Chloride generated from aqua regia refining. I the case of aqua regia, you have no choice but to generate Silver Chloride so it has to be dealt with. With good rinsing, the sugar reduction method can produce 0.999 Silver and allow you to skip the cell entirely.
The silver will crystalize out on the rod, but not re-dissolve, since the sulfuric acid is now too cold to react with it. You'll need to knock silver off the rod, especially if you've dissolved the max amount of silver the acid can dissolve. It'll form a solid crust over the copper rather quickly.
