Green Wealth in Waste Products

Speaking of the first reaction of mine people? Dust in the sky, noise, high chimneys. This is often your first impression, and smelting copper ore will produce tailings, waste residues, sulfur, but also consume a lot of energy.

Guixi City, Jiangxi Province, has established a copper industry recycling economy base dismantling processing zone, in which hundreds of thousands of tons of waste mechanical and electrical products can be converted into recycled copper every year.

Guixi City currently has more than 70 copper smelting and processing enterprises, of which Jiangxi Copper Group produces 1 million tons of electrolytic copper annually, and needs to import more than 700,000 tons of copper raw materials annually, resulting in great pressure on resources. In order to break through the bottleneck of copper raw material demand and copper resource scarcity, the city innovated development ideas and made use of domestic and foreign scrap copper resources to create the first centralized dismantling and utilization processing park of scrap mechanical and electrical products approved by the Ministry of Environmental Protection in the mainland, which was honored as a ldquo; urban mine-rdquo;.

With the import of the seventh kind of waste & ldquo; Shanghai & mdash; Jiujiang & mdash; Yingtan & rdquo; land-sea intermodal transport and & ldquo; Ningbo & mdash; Yingtan & rdquo; Haitielian intermodal transport clearance has been approved, and containers filled with waste metals flow continuously into Guixi & ldquo; waterless Port & rdquo; and 24 dismantling enterprises transported to dismantling processing zone through logistics platform. Industry; After manual and mechanical disassembly and processing of & ldquo; rough copper & rdquo; and then shipped to more than 70 copper processing enterprises in Guixi, processing into more than 100 copper products. Last year, the base paid 313 million yuan in taxes and realized 22.302 billion yuan in main business income.

It is understood that after the completion of the copper recycling economy base, 1.8 million tons of annual dismantling capacity can be formed, and 450,000 tons of recycled copper can be provided for Jiangtong Group and local copper enterprises every year. Compared with the use of copper mine, every 10,000 tons of recycled copper, enterprises can discharge 1.2 million to 1.5 million tons of tailings, 40,000 to 60,000 tons of smelting slag and 3,600 tons of sulphur, save energy equivalent to 59,000 tons of standard coal, reduce production costs by more than 6 million yuan, and achieve remarkable environmental and energy-saving benefits.

Guixi City was officially approved by the State last year as a demonstration base for “ urban mineral resources .
