Aqua regia is useful as a solution to refine gold. It is not a good method to recover gold from trash (electronic scrap). You should learn first how to mechanically separate the gold from the other trash (organics and troublesome base metals), and then leach or further concentrate the gold by leaching other base metals from the gold, basically concentrating the …
Researchers have developed an efficient new way to use graphene to recover gold from electronic waste, without needing any other chemicals or energy. Discarded electronics can be a gold mine...

Article Summary X. To remove gold from circuit boards, start by purchasing concentrated nitric acid from an industrial or chemical store. You'll also need a face mask, safety glasses, and industrial gloves to work with nitric acid, since it can harm your skin and eyes and cause nausea if it's inhaled.
How to refine scrap gold. Recycling old gold products can be a great way to turn unwanted or damaged jewellery into profit. There are two main methods of refining scrap gold; melting or chemicals. Traditional methods used centuries ago can still be used today, but the process of refining gold is difficult and can be dangerous.
The article introduces a three-stage process where copper is first dissolved from electronic waste, followed by silver and, finally, gold. This way, metals can be selectively separated from plastic, ceramics, and other …
kashiffat, There is so many different ways to do something wrong, there are only a few way to do it right. but the problem of giving you the kind of answer to the question you ask, is it would take us writing books of information, just to tell you how to do one type of scrap,and even if we wrote those books, it still would not help you learn how to recover and refine your scrap, …

My suggestion would be to get that day job. Find an income stream other then refining. Your pictures show maybe a gram of gold. That's after many hours of work separating material into piles that would need to be processed in different ways requiring different acids and different equipment, much more then the $40 gram your going to get, which no one will buy for …
Ascorbic acid helps to precipitate the gold in preparation for melting. When this happens, the light green solution will turn brown. Once the gold has precipitated, it is now time to separate it from the solution. Place a coffee filter on the opening of a funnel beaker and pour the solution through the filter. Step 12: Melt the gold

Refined Quartz is created by smelting 1 Quartz in a furnace with 1 coal for fuel. 1 Fire Quartz can also be placed in a furnace with 1 coal to produce 3 Refined Quartz. It can also be obtained in a variety of ways.. It can be sold for 50g.Until obtaining the Crystalarium it is a lot faster and easier to obtain Refined Quartz via the Recycling Machine than from quartz itself.
