   High-priced recycling and auctioning of waste gold from electroplating plants, information on the method of recycling and auctioning of electroplated gold and silver, a new technical route, harmless and advanced treatment, and multiple products obtained through multi-step operations, realizing full recycling, auction and efficient use Resources. This process simplifies the process and incorporates a variety of advanced technologies such as sprayed direct electrodeposition continuous ion friendly, and information on the recycling and auction of gold-plated scrap. The metal in the raw materials is recycled and auctioned. Information about the gold-plated water recycling auction. It improves the workshop production environment, saves energy and reduces emissions, while the entire process is simple and reasonable to operate, reducing operating costs. The gold plating recovery auction method segmented electrodeposition is based on changes in the concentration of metal ions during the electrolytic deposition process, and by controlling the corresponding current density and electroosmotic flow rate, the effect of maintaining product quality, reducing energy consumption and saving time is achieved.


 
   The method for online purchase of scrap gold recovers metals such as copper, gold, palladium, silver, etc., with high purity and high yield. The recycled auction metal can be used directly without further purification. The sale of scrap gold lots simplifies the process and reduces further production. And equipment costs. It can be seen that the method of the gold-plated recycling auction method comprehensively treats ton-year old circuit board PCBs. From the actual production process, the gross profit is as high as more than 10,000. The method of the gold-plated recycling auction method can significantly more effectively separate various materials. The circuit boards and PCBs that are worn out in the waste materials are recycled and auctioned off precious metals to realize resource recycling and reuse, indirectly reduce mining, felling trees, reduce energy consumption and pollution in the metallurgical processing of mines, and have good social and economic benefits. Detailed description of what is scrap gold. The following describes the details of the specific embodiments of the gold-plated recovery auction method in conjunction with the examples below. Embodiment The method for harmlessly treating the bottom plate drift of the old circuit board PCB in this embodiment includes the following steps: one-step leaching and separating copper and tin. The old circuit board PCB is crushed and sieved to obtain metal powder; the metal powder is added to sulfuric acid with a concentration of , The heating aeration liquid-solid ratio is the extraction temperature for a period of leaching.


 
   During the extraction time, copper and tin enter the leachate, and the copper content in the leachate is as follows: part of the tin is suspended in the leachate in the form of tin ash, one stage of leachate and one stage of leaching The mud is obtained through a single filter, and information on where there is a gold-plated silver recycling auction. Using hydrogen peroxide and sulfuric acid, one stage of leaching sludge is heated and stirred for two stages of nitrification leaching, liquid-to-solid ratio, refining temperature, and information about the recovery and auction of copper gold-plated chains. Refining time, through a single-stage filter, obtain two-stage nitrification leachate and two-stage nitrification leachate; the sulfuric acid concentration is, the molar ratio; combine one-stage leachate with two-stage nitrification leachate, and add flocculant. Regarding Ganzhou platinum water recovery auction News. The tin ash in the leachate is flocculated and precipitated to obtain titanium dioxide slag and copper bath, which are then filtered through cascade; the copper bath is used for iron and impurity removal process, and the copper bath is purified; the flocculant is gold water and gold salt, and the mass fraction is: The volume ratio of the filtrate is, and the flocculation time is; sprayed direct electrodeposition uses a purified copper bath for electrodeposition of copper-carrying sprayed direct electrodeposition equipment, and information on the recovery and auction of gold-plated electronic parts. Bulk scrap gold is for sale and obtains more gold water than copper electrodeposition; the electrodeposited copper uses a staged electrodeposition process, specifically as follows: gold water purification and enrichment is more than copper electrodeposition and copper electrodeposition, gold water is used The reflux step is leached, and the leachate is electrodeposited and carried.
