Gold plated pin recycling_ Gold Plated Pin Recycling and Extraction Technology

The rapid development of the global electronics industry has led to an exponential increase in the amount of electronic waste. Among these waste materials, gilded pins are an important resource with a high gold content. In order to achieve sustainable utilization of resources, it is necessary to recycle and extract gold plated pins. This article will provide a detailed introduction to the principles, methods, and advantages of gold plated pin recycling and extraction in practical applications.

The Source and Value of Gold Plated Stitches

Gold plated pins are widely used in various fields such as electronic products, communication devices, computer hardware, etc., such as connectors, sockets, IC chips, etc. The excellent conductivity of metals, especially the conductivity and oxidation resistance of gold, are extremely prominent among many metals, making them widely used in the electronic field. However, with the upgrading of products, a large number of discarded electronic products containing gold-plated pins have been discarded. Recycling and extracting these gold containing waste materials can achieve effective utilization of resources, reduce environmental pollution, and also have certain economic value.

Principle of Gold Plated Pin Recycling and Extraction

The key to recovering and extracting gold plated pins is to effectively separate metals and non-metals from discarded electronic products. Firstly, it is necessary to disassemble the discarded electronic products and classify the components containing gold-plated pins. Next, separate metals and non-metals through physical or chemical methods.

Method for recovering and extracting gold plated pins

1. Mechanical method: Waste electronic products containing gold plated pins are crushed and crushed through equipment, and then metal and non-metal are separated through physical methods such as screening and air separation. 2. Melting method: Heat waste electronic products containing gold plated pins to a certain temperature to melt the metal. The density difference between metal and nonmetal can be used to separate them by gravity separation. 3. Wet method: cyanide method, Chloride process method and other chemical methods are mainly used for metal leaching and separation. Among them, cyanide method is currently the most mature and widely used method. By adding Sodium cyanide solution to the waste containing gold plated pins, gold can be leached in the form of gold cyanide. Then, zinc powder replacement method or electrolysis method is used to convert cyanide gold into metallic gold. The chlorination rule is to convert gold into soluble Gold(III) chloride by adding acidic chloride solution. Then, Gold(III) chloride is converted into metallic gold by reducing agent or electrolytic method. 4. Biological method: By the action of microorganisms (such as sulfur reducing bacteria, iron reducing bacteria, etc.), the gold in the waste containing gold plated pins is converted into soluble compounds, and then the gold in the solution is extracted through chemical methods. This method has good environmental performance, but the processing cycle is long, making it suitable for waste with low concentration of gold.

In practical applications, appropriate recycling and extraction methods should be selected based on the characteristics of waste to achieve the best recycling effect. At the same time, we continuously research and innovate gold plated pin recycling and extraction technologies to improve the recycling rate and extraction purity, and make contributions to promoting the efficient recycling and utilization of waste electronic products.
