For Silver it is any Chloride. NaCl or HCl will bot do it.
Then you will have white Silver Chloride and can smelt it or convert it to Silver.
Or you can Cement it out with a Copper bar, which will give you around 99% (give or take) Silver directly.

You should have been here long enough to know or have researched this by yourself, right?

Can we get 99% purity silver from Silver chloride by reaction of NaOH and then with Dextrose.?

Can we get 99% purity silver from Silver chloride by reaction of NaOH and then with Dextrose.?

Not sure, but think 95-99% is obtainable depending on the quality of the process and work.

Can we get 99% purity silver from Silver chloride by reaction of NaOH and then with Dextrose.?

Some even prefer it to get 99.9% pure.
Washing the silver chloride is the most important. And checking wash water if the chloride is clean with some lye.

Vague question only deliver vague answers You need to be specific.

At least for sake of your own benefit. What is the purity requirement ? How much you have ? What is the composition of the material ? Does you have any experience with silver refining ? Or chemistry in general ?

We cannot answer these questions. You need to do so. Procedures can differ quite a bit with different feeds, despite both ending in 999 Ag.

Does you have proper smelting equipment ? Are you able to perform lye/sugar silver chloride conversion to silver without being injured ? What does your material contain ? Is it lead-free ? Tin-free ?
