Technology of extracting copper and nickel from electroplating mud
The technology of extracting copper and nickel from electroplating mud using copper and nickel extractants is a common process, which can achieve efficient and low-cost extraction and recovery of valuable metals such as copper and nickel in electroplating mud. DZ988N copper extractant and DY319 nickel extractant are two commonly used extractants.
DZ988N copper extractant is the only nickel cobalt separation type copper extractant with good selectivity and anti-interference ability. It can efficiently extract copper from copper containing electroplating mud and retain other metal ions such as nickel and zinc in the solution. The use of DZ988N copper extractant for copper extraction requires optimizing the extraction conditions such as pH value of the solution, extractant concentration, temperature, and time. Meanwhile, DZ988N copper extractant can also be recycled, reducing extraction costs and environmental burden.
DY319 nickel extractant is a composite leaching agent for nickel and cobalt in electroplating mud. It can extract nickel while also reducing impurities such as copper and iron. When using DY319 nickel extractant, it is necessary to optimize the pH value, temperature, extractant concentration, extraction time and other parameters of the solution to achieve the best extraction effect. The use of DY319 nickel extractant can reduce production costs and recycle valuable metals. It is also necessary to further promote and apply DY319 nickel extractant.
In practical applications, copper and nickel extractants can be repeatedly applied to extract copper and nickel from electroplating mud to improve extraction efficiency and recovery rate. In addition, for electroplating mud containing multiple valuable metals, different extraction schemes can be selected based on different extractants to maximize the recovery rate of valuable metals.
Overall, the technology of extracting copper and nickel from electroplating mud using copper and nickel extractants is a practical and efficient extraction method, which is of great significance for the recovery of valuable metals and the reduction of environmental pollution. With the continuous improvement of environmental awareness, more and more enterprises are using copper and nickel extractants for the extraction and recovery of valuable metals such as copper and nickel in electroplating mud. Compared to traditional physical methods such as sintering and leaching, extractant technology is more efficient, low-cost, and environmentally friendly, greatly reducing the discharge of wastewater and solid waste, and reducing production costs. Therefore, copper extractant and nickel extractant technologies have broad application prospects in the future and can be promoted to more fields.
