The characteristics and demand analysis of silver resources in China under the background of new energy

Objective Silver, as an important precious metal, has both industrial and financial properties and is crucial to promote national economic and social development. Therefore, it is important to analyze systematically the characteristics of silver resources and demand trends for emission reduction and resource security in China.Methods From the perspective of the development of the silver industry, the characteristics of the application, geology, supply and demand and market of silver are summarized in China. Based on this, according to the demand driven difference between industrial silver and non industrial silver, the demand of silver is predicted using S-curve and ARIMA models in China from 2022-2035.Results Based on the resource status and demand forecast results of silver mines, the following results are obtained:(1) Silver mines have the geological characteristics of "four more and four less". It means that the total amount of resources is large and the available resources are few; more small deposits, less large deposits; more lean ore, less rich ore; more concomitant deposits, fewer independent deposits; (2) With the continuous growth of silver application field, domestic mine resources and renewable resources can not meet the demand, so it is necessary to import silver ore and other concentrates (used to produce silver by-products, such as lead concentrates, zinc concentrates, etc.) to supplement the gap; (3) From 2022 to 2035, the demand for silver in China will continue to grow, from 5800 t to 9500 t, with an average annual growth rate of about 3.7%; (4) From 2022 to 2035, the demand for industrial silver in China will grow rapidly, from 3800 t to 7000 t, with an average annual growth rate of 4.4%. Photovoltaic systems are the main field driving the growth of industrial silver demand; (5) From 2022 to 2035, the demand for non industrial silver in China will grow slowly, from 2000 t to 2500 t, with an average annual growth rate of 1.7%.Conclusions Based on the above research results, in order to promote the development of the silver industry chain, the following suggestions are put forward:(1) The position and role of silver in the future national economy should be paid more attention; (2) A variety of ways should be adopted to ensure the supply capacity of silver resources; (3) The added value of industrial silver products should be improved to provide guarantee for energy transformation and high-end manufacturing by increasing technological innovation and carrying out deep processing; (4) The national and private silver reserve and security system should be established to avoid large fluctuations in silver prices.
