The once-destroyed abandoned mines can really re-generate through the comprehensive management of land, and embark on the green road of solid waste utilization, new building materials, permeable paving building materials and other circular economy, and the integration of the first, second and third industries?

Dongfengling, Lishui County, Jining City, Shandong Province, promoted the demonstration project of coordinated development of industrial resources comprehensive utilization industry, and realized the wonderful butterfly change of bad land and fertile land and waste minerals.

1 Conversion development ideas,

Abandoned mining area is also a treasure trove of resources

Shandong Yishui Huifeng Agricultural Development Engineering Co., Ltd. is a comprehensive development enterprise integrating land restoration, solid waste resource utilization, ecological agriculture sightseeing and cultural tourism. It is the largest farmland restoration and solid waste resource utilization demonstration in Shandong Province. enterprise. The company was built in an abandoned mine. There are no high-rise buildings. There is only one row of bungalows, followed by two “mountains” of sandstone and aggregate about ten stories high.

According to reports, Surabaya original is not on the scale of iron ore beneficiation enterprises more than 200, at the end of 2008 after being forced off the county government, the legacy of more than 20,000 acres of iron gabbro indiscriminate area has not been effective governance .

At that time, the abandoned mining area was full of potholes. The depth of the pit was about 10 meters deep, and the shallow ones were also two or three meters. The waste rock of various sizes was everywhere, and there was no flat land. The original cultivated land and vegetation were destroyed, the ecological environment was deteriorating, soil erosion was serious, the contradiction between people and land was prominent, and the income of farmers was damaged, which brought unrest to the society.

However, such a run-down mining area also hides huge reserves of waste rock and tailings. It is estimated that only the granite waste rock and waste mineral resources that can be exploited and utilized in the Dongfengling granite resource area will reach more than 100 million tons; the Huichangyan mining area in Shengshui Town and Zhangzhang Town will cover an area of ​​over 30,000 mu. The reserves of iron-bearing gabbro reached 400 million tons. If it can be fully developed, it can create more than tens of billions of dollars.

Resources are business opportunities, and many companies are eager to try.

In the end, the Lishui County Party and County Government selected Lishui Huifeng Agricultural Development Engineering Co., Ltd. to carry out land consolidation and implement progressive management of the abandoned mining area, and allowed the company to reuse valuable mineral resources.

Faced with this rich and abandoned resources, Huifeng Agricultural Development Company is determined to take a foothold in the field.

According to the national characteristic town construction policy and the resources of the abandoned mining area in Dongfengling, Huifeng Agricultural Company initiated a land restoration project in the abandoned mining area of ​​Dongfengling through in-depth investigation and careful investigation. The newly built town of Dongfengling will be the most beautiful ecological first town in Lishui, which is a trinity of land ecological restoration, special town construction and high-end tourism resources.

2 innovative process technology,

Fine treatment of mine solid waste

Initially, the company followed mining solid wastes of valuable metal elements in the recycling principle, established in mining processing 4,500,000 tons of solid waste in a conventional production line of mineral beneficiation process. However, since the completion of the production line in 2013, it has experienced a market decline in the ore industry. There is a continuous loss in production and operation, and land restoration work is unsustainable without sustainable capital investment.

Under this circumstance, Huifeng Agricultural Company attaches great importance to process innovation and technology research and development of solid waste comprehensive utilization. At the end of 2015, the company independently developed a new new technology for comprehensive utilization of solid waste, and built the first wet-process fine-graded high-quality aggregate production line in China.

The wet fine grading production line completely changed the original “extensive”, transforming the traditional process of extracting iron fine powder into the production of high-quality building materials, supplemented with iron fine powder and fine mud as land complex. The new “intensive” production process of earthening materials has increased the comprehensive utilization rate of abandoned mining resources from 5% to 100%, and the energy consumption is reduced by nearly 40% compared with traditional production processes.

In terms of emission reduction, the new process adopts a new wet operation process, and the dust emission is basically zero, and there is no air pollution. In terms of sewage discharge, the process adopts a fully closed-circuit sedimentation self-cleaning circulating water utilization process, and the water circulation utilization rate is over 92%, and the new solid waste comprehensive utilization process is all processed by physical methods without any chemical pollution, so the process No pollution to the overall water resources.

After the transformation and upgrading, the new technology can process 6 million tons of waste rock and repair more than 200 acres of land. Production of plastic washed gabbro high-quality building aggregates at various levels of 5 million tons, fine ore fine powder 300,000 tons, iron fine powder 300,000 tons, assembled energy-saving houses 300,000 square meters, used as sponge city permeable bricks 600,000 square meters , high-performance commercial concrete 600,000 square meters, reclaimed earth material 500,000 tons. Shandong Iron and Steel Group, Wuhan Iron and Steel Group, and Hebei Iron and Steel Group have visited Jining and are planning to introduce this production process.

3 service "Sponge City",

Realize the industrialization of new building materials

Fine graded high-quality aggregates, no matter how good or raw materials, at best, turn the mine waste rock into raw materials, and the profit is meager. Huifeng Agricultural Company knows that only by increasing the added value of products and lengthening the industrial chain can we fully realize the full utilization and comprehensive utilization of mine waste rock and realize the transformation and upgrading of enterprises.

To this end, Huifeng Agricultural Development Co., Ltd. and the listed companies Beijing Jiangong Huachuang Technology Development Co., Ltd. and Ruitu Holdings (China) Co., Ltd. have carried out strategic joint ventures to develop new building materials industrialization projects using mine waste rock resources.

On February 6, 2016, the General Office of the State Council issued the "Several Opinions on Deepening the New Urbanization Construction", clearly proposing to vigorously promote the assembly-type construction, reduce construction waste and dust pollution, shorten the construction period and improve the quality of the project. Strive to use 30 years or so, so that the proportion of prefabricated buildings to new buildings reaches 30%.

Huifeng Agricultural Company realized that this will give birth to a trillion-level market.

Therefore, they used the mine waste rock to produce combined light-weight wallboards, and also used self-produced gabbro aggregates to produce permeable paved prefabricated products and fabricated energy-saving houses. This project has an annual output of 3 million square meters of permeable pavement prefabricated products, 1 million square meters of assembled energy-saving houses, and an annual sales income of 2 billion yuan. Huifeng Agricultural Company's goal is to become the country's largest sponge city permeable paving, assembly-type housing production base.

Today, Huifeng Agricultural Development Company has been listed as the sole raw material supplier of sponge city construction in Shandong, Henan and Jiangsu provinces by many well-known professional manufacturers of permeable concrete. It is working with a number of domestic research institutes and universities to jointly develop projects such as gabbro processing rock wool and gabbro high-strength sintered ceramsite. It is expected that these two high-tech industries will be industrialized by 2018. .

4 develop sightseeing tours,

Create the "most ecological town"

The idea of ​​Huifeng Agricultural Company is to continue to invest in land restoration and ecological sightseeing agriculture by utilizing the benefits of industrial industry, until the ecological tourism output yield exceeds the industrial industry, and finally replace the industrial industry to form a new type of self-hematopoietic function that does not rely on government finance. Agricultural industry.

Since its implementation in 2011, Huifeng Agricultural Company has completed more than 1,200 acres of land restoration, and has repaired more than 200 acres of land per year, planting more than 700 acres of high-quality grapes, apples, and the government has not given a penny of financial subsidies. More than 300 acres of fruit trees such as cherries, peaches, pears, etc., more than 100 acres of green standard vegetable base, more than 100 acres of ornamental forest nursery, ecological tourism agriculture industrialization has begun to take shape.

In 2015 and 2016, the company held two consecutive “Huifeng Fresh Grapes Picking Festival”, which brought more than 20,000 people to the sightseeing crowd, picked more than 150 million kilograms of grapes and other organic fruits and vegetables, and gained more than 2 million yuan in ecological agriculture. . The benefits of ecological agriculture and tourism agriculture have gradually emerged. With the continuous improvement of land remediation area and the extension of the solid waste comprehensive utilization industrial chain, the company's profitability will be greatly enhanced, and the company's investment in land restoration and sightseeing agriculture will also increase year by year.

Huifeng Agricultural Company is very confident that in the near future, the agricultural tourism industry will become the company's most important source of profit, and they will explore the circular economy of the “two industries” The model will show its enormous social and economic benefits.

Today, Huifeng Agricultural Company's project has been listed by the Ministry of Industry and Information Technology as a demonstration project for the coordinated development of industrial resources comprehensive utilization industry in Beijing, Tianjin and Hebei. The company is developing selected from titanium iron ore gabbro, meanwhile, plans to build a green technology research and development tailless mineral processing platform, the production process, technology and equipment to improve, to vigorously promote China's green mine construction and solid waste resources Make use of it and make your own contribution.

Green, symbolizing life. Green development is the expectation of the succession of mountains and rivers, and it is the pursuit of sustainable economic and social development. The change in the mountain of the ordinary mining area in Dongfengling, Lishui County, Jining City is not a microcosm of China's comprehensive promotion of green development methods and lifestyles.
