"I want to 'eat' out of all tailings Jinhua fluorite mine." Wuyi Shenlong flotation Ltd. Chairman Zhou love Ma said.
In 2004, his company had “eaten†100,000 tons of tailings and recovered 16,000 tons of fluorite fines. This year, it has "eaten" 150,000 tons. In doing so, it is equivalent to “Dragon†adding a fluorite mine that consumes 100,000 tons of reserves per year to Wuyi.
The practice of “Shenlong†has been fully affirmed by the provincial and national land and resources departments. Wang Zhihong, director of the Mineral Resources Reserve Evaluation Center of the Ministry of Land and Resources, commented that “Shenlong†relies on science and technology and through independent innovation, using secondary flotation of abandoned tailings to produce qualified fluorite fine powder, and finally using waste slag to make bricks, which saves fluorite. Resources have improved utilization, eliminated environmental pollution, and achieved ideal social, economic and environmental benefits. To this end, the Ministry of Land and Resources has promoted the practice of “Shenlong†as a model for mining enterprises.
In recent years, due to the rapid development of the fluorination industry, the demand for fluorite fine powder is very strong, while the fluorite resources in Wuyi County currently only have about 30 million tons of reserves left. Some of the easy-selection ore have been exploited in large quantities, and the current low-grade mining The amount of minerals can no longer meet the raw material demand of eight flotation plants in the county. Many manufacturers have to purchase raw materials from distant counties such as Lishui, Tiantai, Tunchang and Jinyun to maintain daily production.
The traditional mining and processing of fluorite has caused hidden dangers to the local area while causing the depletion of resources. According to the county's conservative statistics, the current number of tailings abandoned in Wuyi has reached more than 3 million tons, requiring more than 200,000 square meters of space for stacking; 8 flotation plants in the county have to add 900 tons of tailings every day. These mountainous tailings, sunny days and dusty weather, when encountering heavy rain or continuous rain and other weather, it is easy to cause geological disasters such as mudslides; usually when the open air is stacked, as the rain washes, the sewage flows into the farmland, causing the land to be knotted and affecting the crops. Growth; due to excessive levels of calcium fluoride in the water, sewage will seep into the ground and cause groundwater pollution.
"Shenlong" has a flotation plant in Wuyi Qikongtang. The annual flotation capacity of ore is 80,000 tons. However, due to the lack of tailings dumping site, the pollution is large. Every year, the mine is fined more than 1 million due to tailings dumping and pollution. Yuan, let "Dragon" feel a headache, find the road to independent innovation from the circular economy. To this end, “Shenlong†has invested more than 10 million yuan to re-use tailings with 20% calcium fluoride content, repeated experiments and improvements on mineral processing equipment and process, and formed a set at the end of 2003. Flotation equipment and process flow with independent intellectual property rights. After the company's flotation equipment and process flotation tailings, the content of calcium fluoride is only 4%, and 16% of the content becomes the acid-grade powder and building-grade powder in the fluorine chemical industry.
After “drinking and exhausting†the useful components of the tailings, “Dragon†cooperated with Beijing Sinoma Institute of Technology to make the slag into non-burning load-bearing bricks and non-load-bearing bricks that can be used in both civil and high-rise buildings. Porous bricks have effectively solved the problem of pollution control of abandoned slag that has remained unresolved in China. With the technology of independent innovation, the survival problem of “Shenlong†has been solved. It not only solves the pollution problem of the Qikongtang tailings, but also “eats†more than 100 tons of tailings produced by the mine every day. To this end, the company acquired the Wuyi Quanxi Flotation Plant and built it into a professional “eat†pollution factory that processes 150,000 tons of tailings annually. It can easily “eat†the tailings produced in the county on the same day; It can use waste residue to produce more than 100 million pieces of non-burning building standard bricks, saving 60,000 square meters of clay. Since then, the "Shenlong", which was originally a large polluter, has now become a "eat" filth king.
"Shenlong" achieved sales revenue of more than 30 million yuan last year, profits and taxes of 4.5 million yuan; this year, the company's sales revenue and profits and taxes increased by 70% and 55.6% respectively compared with last year. Zhu Xianlin, the company's chief engineer, said that in this growth, the increased sales revenue and benefits of tailings treatment are considerable.
Zhu Xianlin calculated an account: the original ore with a content of 1% grade has a value of 4 yuan per ton, and the value of processing into a product rises to 7 yuan. The profit per ton of raw ore processed is about 20 yuan, and 1 ton of product is processed with 3 tons of raw ore. The final profit is 60 yuan; with tailings processing, 16% of calcium fluoride is extracted, the value is 112 yuan, 1 tons of products are processed with 7 tons of tailings, and the final profit is 125 yuan, which is doubled than the original mine. many.
In addition, slag bricks can also produce better economic benefits. For example, a brick factory that “eats†150,000 tons of tailings slag in one year, the investment of the plant is about 8 million yuan, and the annual output of fire-free bricks is 150 million pieces, which is sold at a price of 0.20 yuan per piece. More than 2 million yuan, 3 years to recover the investment.
“Dragon†is preparing to expand its tailings processing capacity to 300,000 tons in 2006. On this basis, it will gradually expand the tailings treatment scale, and strive to “sweep all the tailings of Wuyi and other Jinhua’s other counties and cities in 10 years. And light." In this way, the fluorite processing industry chain can be effectively extended, the tailings treatment costs can be reduced, new profitable projects can be added, and the enterprise beneficiation project can have a larger profit margin and better profit expectations.
