Is it really possible to make money refining gold?

Refining can make money, but only if you master the corresponding technology and market trends.

In the market, there is a lot of volatility and a lot of market demand, so you can earn the difference by refining. However, it is important to note that if the market trend is not in favor of ******, or if you are not skilled enough, there may be a risk of losing money.

In addition, refining also requires certain costs, including raw material costs, equipment costs, labor costs, etc., so it is necessary to reasonably control costs to ensure that they can be profitable.

In general, refining can make money, but it needs to master the corresponding technology and market trends, and at the same time, it is also necessary to control costs. It is recommended to fully understand the market trends and risks and seek professional guidance and training before trading.

**Classification and identification, each line has a way to make money, this line has a technical threshold, first of all, you need to identify which products contain**, which do not, how much gold content, because electronic products are updated very quickly, so these need to continue to learn and accumulate, only people who know how to make money. For example, there is a small part of the circuit board in some computer motherboards, generally around grams, the content is mainly concentrated in the CPU processor, a small piece of CPU processor has some gold content up to grams, and the entire motherboard can be refined in grams, and there are also some mobile phone circuit boards, memory modules, and some resistors and capacitors are also coated, and the highest content is the air conditioning chip.

**Motherboard to make money, after learning to identify, **motherboard to make the difference is also very good, now**circuit board a pound of a few dollars to a dozen dollars, know how to sell after a few dozen or hundreds of dollars, it is very easy. Don't do it if you don't know how to do it, there will be a lot of pitfalls in it, especially the CPU that sells very cheaply on the Internet, I dare to say that 99% of it has been washed by others, and it will definitely lose money after taking it back. There are also some circuit boards that look yellow, everyone thinks they are, some are made of copper, copper will become dark after a long time, some will turn green, ** will not change color, the color is golden and bright, so we must study carefully and carefully distinguish in order to make money.

At the beginning, it is recommended that you can make circuit boards, because there are also circuit boards, but there are only a small part, because the content is small, and it is mixed between various capacitors and resistors, so the probability of making a fake is not large, so it will be safer to operate.

Refining**, now**refining is also more environmentally friendly, but the procedures are still handled. The first step is to calcinate the high-temperature furnace to dispose of the capacitors, resistors and some impurities inside; In the second step, some chemicals (aqua regia, etc.) are used for decomposition. The third step is to continuously heat and melt, this temperature should reach a high temperature of 1500 degrees, because these circuit boards contain different metals in it, they need to be separated layer by layer, and the density volume melting point of each metal is different, and it needs to be separated layer by layer.

The last thing that comes out is **, of course, there are some other *** that are refined, such as copper, tin, zinc, lead, etc., and the main income is **. The main cost of refining is the high-temperature furnace, the higher the purification technology, the greater the profit, now **** 380 yuan a gram (reference price on May 5, 2020), of course, the **** refined will not be so high, because the purity does not meet the requirements, so the industry **** one gram **** is about 250 yuan. Now there are also specialized companies **these** purify again, earning the difference in the middle.

Of course, it makes money, and the profit margin of waste circuit board refining is very large Because the cost of electronic waste is low, but the value of refining is very high.

3. All the items that are refined online are better not to believe.

First of all, from the legal point of view, it is a rare and regulated resource, and it cannot be refined casually, and the project of refining must at least have the approval of the province or even the first place.

Secondly, logically speaking, it is indeed very profitable, but one sentence you have to believe in this year is that there are few good projects, but there is a lot of money that can be invested, and you have no money, and you don't have a few rich friends and relatives? Even if you work with those people, it's better than working with you! And there are many points, and the so-called fertilizer and water do not flow into the fields of outsiders!

If it were me, I wouldn't share such a good project with strangers, let alone spend money on friends who cooperate with Zhang on the Internet.

Regarding the authenticity of the network, if such a good project is looking for a partner, at least there must be an open recruitment letter issued by the company, just relying on online advertisements or a few paragraphs of text, there is no credibility at all.

The best products that can be extracted are: all kinds of gold-containing electronic components, all kinds of gold-containing alloys, and all kinds of jewelry waste.

1. All kinds of gold-containing electronic components.

Some contacts, leads, and circuit boards of instruments and electrical appliances such as video recorders, record players, measuring instruments, analyzers, computers, etc., also contain gold.

2. Various alloys containing gold.

The alloy has a high gold content. There are also many low-gold alloys, which are easily forgotten and treated as ordinary metals**.

3. All kinds of jewelry waste, anode mud, batteries, solder alloys, dental alloys, gold-plated devices and chemical, electronic, pharmaceutical, electroplating and jewelry and other devices involved in the use of gold are all contained in gold.

Gold extraction technology, mainly for the purpose of environmental protection, is a technical research, the realization of resource recycling of electronic waste, electronic waste, and the realization of pollution-free environmental protection treatment methods. It not only enables the enterprise to achieve good economic benefits, but also promotes the development of environmental protection, the regeneration of waste resources, and the benefit of the country and the people.

The ** refined by yourself cannot be bought and sold.

It is not illegal to refine ** at home, but if you buy and sell it yourself, it will constitute the crime of illegal business. The law stipulates that all gold and silver mined by factories and mining enterprises, rural communities, military units and individuals engaged in gold and silver production must be sold to the People's Bank of China and must not be sold, exchanged, or retained on their own.

The objective aspect of the crime of illegal business operation is to operate franchises, monopoly goods or other restricted items without permission, to buy and sell import and export licenses, import and export certificates of origin, and other business licenses or approval documents provided for by laws and administrative regulations, as well as to engage in other illegal business activities, disrupting market order, and the circumstances are serious. It is mainly to operate franchises, monopoly items or other restricted items that are not allowed to be sold in accordance with laws and administrative regulations.

**Refining of Ridge Calling Ore:

The gold content in the ore is extremely low, and in order to extract **, the ore needs to be crushed and ground and pre-enriched using beneficiation methods or separated from the ore. ** Beneficiation is used more is gravity separation and flotation, gravity separation method occupies a very important position in the production of placer gold, flotation method is widely used in rock gold mines, at present, about 80% of China's rock gold Yingkai mine adopts this method of gold separation, beneficiation technology and equipment level has been greatly improved. <>

Summary. The refining method is as follows: "1. Nitric acid separation method can use nitric acid separation method to pour concentrated nitric acid into a beaker and put the metal that needs to be refined into a beaker.

After that, the beaker is placed on the beaker holder and heated with an alcohol lamp at the same time, after which you can get a flake**. 2. Aqua regia separation method configures one part nitric acid and three parts hydrochloric acid into aqua regia, puts the metal to be refined into aqua regia, and filters it after the metal reaction is completed. After heating, and finally put in the copper sheet for replacement, the ** can also be refined.

3. The sulfuric acid hydrogen peroxide separation method mixes sulfuric acid and hydrogen peroxide in a one-to-one ratio, and then puts the technology that needs to be refined into the sulfuric acid hydrogen peroxide solution.

How is it refined?

Kiss, **refining method is to pour concentrated nitric acid and ** into the beaker, and then put the beaker on the beaker holder and heat it with an alcohol lamp, and you can get flakes after heating for a period of time**. In addition, refining ** can also be made into aqua regia with nitric acid and hydrochloric acid in a ratio of 1 to 3, put the metal into aqua regia until the end of the reaction, and finally heat it and replace it with copper sheets.

**It is a kind of golden yellow, corrosion-resistant***, we all know**Very rare, more precious, so it is regarded as one of the precious metals, and it is more popular in the jewelry industry**After direct contact with highly volatile substances such as perfume and hairspray, it is easy to fade. Therefore, avoid using these products on the area where you are wearing gold jewelry.

2.**The texture is not as hard as it shows, so when not wearing, you should use soft materials such as flannel to hold it and then put it into the jewelry box, otherwise it will be easily damaged by collision or friction with other jewelry. 3.

Similarly, the softer texture of the ** jewelry is easy to deform, so try not to add external force to the jewelry, such as pulling and other actions will make the ** jewelry deformed.
