Refining Gold with Sulphuric Acid

Parting Gold-Silver Alloy with Sulphuric Acid Alloys of 10 grains of gold, assaying 9992, were taken, and alloyed with 10, 15, 20 grains of fine silver respectively. Each alloy was rolled out in the same manner as was adoped for the nitric acid parting; 20cc of strong sulphuric, 92 per cent., acid was used in each case, and the cornets were boiled for one hour.

Gold Recovery Chemicals | E-waste recycling beginners guide

HNO3 as a gold recovery chemicals: Full name of HNO3 is Nitric acid. It is also known as aqua fortis and spirit of niter. Pure nitric acid is colorless but an older sample can be yellow cast due to decomposition into oxides of nitrogen and water. For gold recovery, it is using commercial grade concentration 68% in water.

How to Recover Silver from Nitrate Solutions

The usual method of recovering silver from these solutions is to precipitate the silver by means of common salt. From an ordinary alloy the only salts likely to be precipitated are mercurous chloride and lead chloride. The former would be present in traces only, and would be eliminated in subsequent operations. Lead is generally removed before smelting, but assuming any to be present it will ...
