Not to mess with expensive nitric acid from the pharmacy I found the cheaper way to refine silver. I put 50 gram of Sodium Nitrate from a garden supply shop, (is a common fertilizer) in half liter Sulphuric acid from a car supply shop (is common lead battery acid) and in it unclean silver, in as small parts as possible, milled flat and cut, and/or filings, in a glass coffee pot that can take a gas flame and boil it for one or two hours, (no need for a lid as the water in the weak acid evaporates and makes it stronger) or until all is dissolved, pour the liquid through a common coffee filter. What undissolved metal stays in the filter goes in the next batch. Then I add very fine common kitchen salt, dissolved in a little hot water or just like that; dry. The white yoghurt like substance (precipite) comes down in the liquid, until more salt does stay salt. Then pour the liquid through a new coffee filter and rinse with water until clean, to check add a little amoniac (Janitor strength from the hardware store). If the rinse water turns blue, rinse more. Good to rinse last with distilled water (which I catch from my air conditioner). Put the filter with the white stuff in a crucible in a burnout oven if you have, heat to 800 Celsius, then remove from oven and put the torch, (Propane Oxygen will do) to get 100% pure silver. If you have no oven, let the filter dry , dip in alcohol and heat with torch. Same result. The same procedure for low karat gold, what stays in the filter after 2 hours cooking put in Muriatic Acid with Sodium Nitrate, the gold will dissolve in room temperature, slowly, over night. Filter the liquid, what stays in the filter, rinse well and pour off what is light, any bits and pieces are good for a next time Dissolve some Urea ( also from the garden supply shop) in hot water and pour it slowly in the acid. It will foam and get hot, put your container in a big glass bowl in case it runs over. After the urea solution has gone in sprinkle Metabisulfite (is a salt butchers use to keep meat from turning brown, also used in wine making, water purifying, a common house hold item in a pharmacy) and see it foam and smell it stink, do work upwind. When brown-red particles go down, that is the pure gold.

 Proverbs 17:3  The fining pot is for silver, and the furnace for gold: but the LORD trieth the hearts.

 Malachi 3:2-3 But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner’s fire, and like fullers’ soap: And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.
