Compared with similar products at home and abroad, this series of equipment has significant technical advantages, which are mainly reflected in:
1. High gold desorption rate: the carbon-poor gold grade after desorption is less than or equal to 50g/t (the same industry products are generally less than or equal to 100g/t).
2. High primary electrolysis rate: the average electrolysis rate of desorption solution is ≥90%. (The products in the same industry are generally around 70%).
3. Accurate gold balance: the actual amount of gold obtained after desorption and electrolysis is consistent with the theoretical gold content in the gold-loaded carbon. (Products in the same industry generally have the phenomenon of "floating gold or accumulative funds", which causes the loss of gold in the processing process and makes the amount of gold unbalanced)
4. Efficient and easy to operate: The whole set of equipment adopts integrated design, signal acquisition, operation adjustment control and safety protection are automated to ensure high efficiency, easy operation, safety and reliability during the entire operation period.
5. Low operating cost: The equipment is made of real materials of special materials (mainly including high-quality insulation materials, all-tetrafluoroethylene insulation materials, fully imported aerospace-grade circulating pumps, high-resistance electric shock heating pipes, etc.). The power-consuming equipment adopts frequency conversion design to ensure the low cost of operation and maintenance while ensuring the desorption electrolysis index.

[ China Instrument Network Instrument Development ] On July 30th, the Hefei Institute of Material Science of the Chinese Academy of Sciences hosted the kick-off meeting of the Ministry of Science and Technology's key research and development plan “Sun Radiation Spectral Space Radiation Reference Load Technology†in Hefei, Anhui. The Ministry of Science and Technology's “Earth Observation and Navigation†key special management office, special responsibility expert, project consulting expert group, project leader and leaders and representatives of the participating units attended the meeting.
Liu Jianguo, deputy dean of the Hefei Institute of Material Science, Chinese Academy of Sciences, delivered a letter of appointment to 11 project consultants. The representative unit promised to perform legal duties, standardize the project implementation according to the relevant key research and development plans, and coordinate the participating units to jointly complete the expected scientific research tasks. . Director Qu Zhe of the Research Institute of Hefei Research Institute reported that Hefei Research Institute has undertaken the state key research and development plan and related management methods, and introduced the division of functions of the project management office. Researcher Zheng Xiaobing, the project leader, reported on the project's basic situation, technical implementation plan and work plan on behalf of the research team.
The consulting expert group agreed that the project is of great significance for promoting the development of quantitative remote sensing in China. It is hoped that the project team will seize the opportunity, strive for excellence, make bright spots, learn from the management model of model task development, further refine management measures, and pay attention to each task undertaker. Work coordination, task scheduling and schedule monitoring, timely discover and resolve technical risks, develop industry-recognized indicators testing and performance verification technical specifications, and further develop forward-looking research based on the completion of the guidelines, planning future model design and application in advance. The program lays the foundation for the development of follow-up tasks.
Deputy Director Xu Wei of the Earth Observation and Navigation Key Project Management Office of the Ministry of Science and Technology affirmed the importance attached by the Hefei Research Institute and the specific management measures introduced, and requested that the Ministry of Science and Technology High-tech R&D Center implement the national key R&D in the implementation of the project. The Opinions on the Legal Responsibility of the Leading Unit of the Planned Project (referred to as “Legal Persons Tenâ€), emphasizing the main responsibility of the project lead unit and project leader, giving full play to the role of consulting experts, strengthening team awareness, strengthening scientific research integrity construction, timely and special management office Communicate important matters, pay attention to results summary and publicity, and jointly provide support for the smooth implementation of the project.
The National Key Research and Development Program “Sun Radiation Spectral Space Radiation Reference Load Technology†project is led by the Hefei Institute of Material Science, Chinese Academy of Sciences, in conjunction with the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Metrology, Southwest Institute of Technical Physics, 11 units including the National Satellite Meteorological Center jointly undertaken, and on May 19, 2018, the Ministry of Science and Technology approved the project, and received special funds to support 85.90 million yuan, with a project period of 4 years (2018.5-2022.4). The project adopts a new working system combining parametric down conversion and low temperature electric alternative measurement, and strives to break through three core technologies: absolute value transfer based on space low temperature radiometer, wide spectrum low noise related photon compliance detection, measurement accuracy and stability verification. The measurement uncertainty of the total solar irradiance of 0.05%, the spectral irradiance of 0.3%, and the earth reflection spectrum radiance of 1%, and the function of measuring the lunar irradiance verification stability.
