At the workshop of Hunan Jinye Environmental Protection Technology Co.,Ltd. in Yongxing Economic Development Zone, workers only need to add nickel smelting waste and auxiliary materials into the batching hopper, and then the molten liquid formed after high-temperature melting and other steps will be centrifuged at high speed and become mineral wool.

With no crude ore in the county, the raw materials used in production are all recovered from industrial wastes. The recycling of waste and residue is not only environment friendly but also creates new value.
However, if building a large industry on a land without resources, developing alone is not a long-term solution.
Yongxing Economic Development Zone has introduced three kinds of top 500 enterprises such as Sino-Platinum Metals, Shengda Resources and GEM, as well as central enterprises and listed companies to settle and invest in the park, attracting other rare and precious metal enterprises to develop in the park.
Currently, the park has formed a rare and precious metal industrial cluster.
By leveraging mechanisms for ecological environment at provincial, municipal and county levels, the park has made efforts to relax the hazardous waste transfer from 50% to 80%, greatly expanding the industrial space.
Last year, the annual revenue of the rare and precious metals industry increased by 15%. It produced 6,000 tons of silver annually, accounting for a stable quarter of the country’s total. It produced 15 tons of gold and 210,000 tons of other valuable metals annually.
The annual production of bismuth, tellurium, and platinum group metals accounted for more than 60% of the country's total. The billion-yuan industry has been increasingly prosperous.
The park has established two specialized teams for the fine chemical new material industry and the rare and precious metal industry to attract large and strong companies.
Leading enterprises such as Yunnan Tin Group and Xuetian Chem have been newly introduced.
Currently, there are 14 enterprises in the park invested by the Fortune Global 500, China's top 500 enterprises and Top 500 private enterprises, state-owned enterprises, and listed companies.
At the same time, it has promoted clean production and energy-saving transformation, successfully developed into a national level green park, and a provincial carbon peak pilot park.
The comprehensive utilization rate of industrial solid waste is 97%, the reuse rate of industrial water is 99%, and the number of green factories at or above the provincial level has increased to 9.
In the production workshop of Yongxing Sino-Platinum Resources Co., Ltd., a new electrolytic silver process, independently developed by the company, shortens the electrolysis time from 48 hours to 22 hours, which greatly reduces the consumption of mother liquor per ton of silver and increases the company's profits.
Jenson Display, a company in the park, won the national manufacturing industry single champion, while companies such as Jinrun and Xiongfeng were rated as provincial benchmarks.
Two intelligent manufacturing enterprises, five workshops, and 28 workstations have been established.
And one provincial-level science and technology achievement transformation pilot base, four expert workstations, two enterprise technology centers, one research and development institution, and two doctoral innovation stations have been added.
The number of “little giant” enterprises at or above the provincial level has increased to 14, with a total technology contract transaction volume of 3.33 billion yuan.
