This article is about aqua regia process for gold dissolving and extracting. Aqua regia is a combination of HCL and HNO3. 3 parts of HCL and 1 part of HNO3 make aqua regia for gold dissolving.
#0183;#32;The effect of TBP concentration on the extraction of mineral acid (HNO 3, HCl) and gold ions from the goldbearing aqua regia solution was studied. The initial concentration (10100 vol%) of TBP in the kerosene was varied keeping other factors constant (5 min contact time, temperature 25, phase ratio (O/A) 1 and Au concentration).
Extracting Gold from Ore by Aqua Regia methodGold Nov 09 2017#183; The usual reason why people do not leach ore direct with aqua regia is the cost of the process not just the chemical cost but the equipment cost of plant to handle aqua regia the health regulations regarding fumes and the disposal requirements of used solutions.
#0183;#32;In this video, we purify Gold that we recovered off of Computer Memory Chips with Aqua Regia. Or Noble Water. Using Hydrochloric and Nitric Acids (HNO3+3 HCl...
The gold will again take on the appearance of metal. If you''ve followed the procedure carefully and used filters, the gold should be % pure with negligible losses. Platinum. If you had platinum in your gold, it will not dissolve, to any appreciable degree, in the room temperature aqua regia.

#0183;#32;I was extracting gold from old computer parts. I first removed the gold using Nitric Acid, neutralized it, and picked out the gold. I then dissolved the remaining scraps with Aqua Regia and it turned emerald green. I''m assuming I have some Copper and other impurities. I left the solution under a hood for some time and it crystallized.

The traditional aqua regia (mixture of Hydrochloric and nitric acids in the proportion of 3:1 volume ratio, respectively) method is used to refine pure gold (24Karat = % purity) from factory
THE DANGERS OF AQUA REGIA: When adding aqua regia to ore, there can be use a red gas given off; THIS RED GAS CAN KILL Sometimes the ore will bubble over, so watch it carefully. Use the aqua regia in an open area and it to the ore very slowly. Aqua regia cannot be boiled or simmered in the house or where it is not well ventilated. This can cause serious illness or KILL YOU! Use a vent hood

Aqua Regia Process: I will explain two different aqua regia process in this article. You can watch the video that I divide aqua regia solution into two parts. In the first method, I add urea in solution until reaction. Urea neutralized the nitric acid. After that, I added SMB powder directly I gold solution.
