I have videos on my website on the entire process.

First watch 'Separating Silver from Gold', then watch 'Converting Silver Chloride - Method 2'.

don't melt the silver chloride. to get silver you have to discompose it. it works but with great losses and nasty chlorine gass. melt the ruined silver chloride with soda ash and coal to save some silver. for the rest of undryied silver chloride follow the advices above

Don't try to melt silver chloride directly. Reduce it to silver metal first. There has been plenty posted here about reducing the chloride with Karo syrup (corn syrup or glucose) easy and no bad fuming then it melts nicely.

Do a search for the method and if you can't find it ask again and I'll look it up.

After you add salt the resulting powder is silver chloride.

Rinse with boiling hot water until wash is completely clear. This takes about 10-15 washes and requires lots of stirring.

Next convert the silver chloride as shown in the videos.

Rinse with boiling hot water until wash is completely clear. This takes about 10-15 washes and requires lots of stirring.

Heat dry and melt the silver.

Watch the videos and you will get it.

1 Kg of fine silver (~9.27 moles) with 541.5 grams of sodium chloride forms 1328.27 g of dry silver chloride (the 'white cement'). If working with alloyed silver multiply all the numbers by the percentage of silver in the alloy. It's never a good idea to dry out the silver chloride before it is converted back to silver.

For 99.99 fine silver you will need to build a silver cell.
