The project was approved by the National Development and Reform Commission, the Ministry of Finance, the State Environmental Protection Administration and the Shandong Provincial Development and Reform Commission, and was listed as a key construction project by the Shandong Provincial Government. The project conforms to the national industrial policy, belongs to the national encouraged development project, and was included in the list of the first batch of copper smelting enterprises by the National Development and Reform Commission. The Ministry of Environmental Protection issued the document 19991February 25th. In 2008 1, it officially passed the environmental protection acceptance of Xiangguang Copper Project. All projects have been successfully put into production.
The investment in fixed assets of the project is 565,438+600 million yuan. After the first phase of the project is put into production, the annual output of cathode copper is 200,000 tons, sulfuric acid is 700,000 tons, gold 10 tons, silver is 300 tons, and crude copper sulfate is 8,300 tons. The sales income is 654.38+02 billion yuan, and the profits and taxes are 654.38+026 billion yuan. After all production, it can produce 400,000 tons of cathode copper, 20 tons of gold, 600 tons of silver, 65.438+0.4 million tons of sulfuric acid and related products annually, achieving sales revenue of 30 billion yuan and profits and taxes of 3.6 billion yuan.
Xiangguang Copper Company established a resource-saving and environment-friendly enterprise based on the development of circular economy, which effectively solved the problem of "three wastes". The comprehensive utilization of reclaimed water, acid production from tail gas recovery and further copper extraction from tailings are realized, which effectively solves the problem of three wastes and realizes the coordinated development of economic, environmental and social benefits. The double flash process realizes the continuous operation of copper smelting. Compared with the traditional PS converter smelting in separate furnaces, the production capacity is greatly improved, and the total energy consumption index of the whole plant is 570kg standard coal /t cathode copper, which is 3 1.74% lower than the national copper industry access index. In terms of water resources utilization, the company invested in the establishment of a supporting sewage treatment center. After being treated, the wastewater from yanggu county and Fengxiang Group is sent to Xiangguang Copper as industrial water, which makes the recycling rate of water in the whole plant reach over 99%. The flue gas generated in the smelting process is completely recovered into the sealed flue to make acid, and 700,000 tons of sulfuric acid can be produced every year; Power generation after waste heat recovery can generate 52.6 million kWh per year. Copper is further recovered from flash slag by slow cooling, crushing, ball milling and flotation, and tailings become high-quality raw materials for other downstream enterprises. At the same time, the company also introduced foreign advanced technology and equipment to recover precious metals such as gold and silver, which improved the utilization rate of resources.
165438+2007129 October, the commissioning ceremony of Xiangguang Copper's advanced double-flash copper smelting project was held ceremoniously, which marked that the internationally advanced double-flash copper smelting technology blossomed in China, bringing China's copper smelting technology to a new level and filling a gap in China's copper industry.
