Special plan for comprehensive utilization of metal tailings (2010-2015)
I. Introduction
With the rapid development of China's economy, the traditional extensive economic growth mode has made the contradiction of China's resource shortage more and more prominent, and the environmental pressure is growing. Taking the road of new industrialization with Chinese characteristics, vigorously developing circular economy, and improving resource utilization are the only way to solve the current constraints on China's resources and environment.
The comprehensive utilization of metal tailings is difficult and involves a wide range of issues. It is not only related to the survival and development of enterprises and industries, but also affects the environment and safety. It is a hot spot of social concern. Compared with the solid waste powder coal ash, coal gangue, tailings utilization technology is more complex, more difficult. At present, the comprehensive utilization rate of industrial solid waste in China is about 60%, and the comprehensive utilization rate of metal tailings is less than 10% on average. In contrast, the comprehensive utilization of tailings lags far behind other bulk solid wastes. Tailings have become the largest solid waste with the largest output and the lowest comprehensive utilization rate in China's industry.
The comprehensive utilization of tailings is a concrete manifestation of implementing the scientific development concept, coordinating the harmonious development of people and nature, developing ecological civilization, and building a resource-saving and environment-friendly society. According to the Law of the People's Republic of China on Circular Economy Promotion and the Outline of the Eleventh Five-Year Plan for National Economic and Social Development of the People's Republic of China, a special plan for comprehensive utilization of metal tailings is formulated and formulated, with a planning period of 2010-2015.
The tailings referred to in this plan refer to the solid waste discharged during the metal ore beneficiation process.
Second, the basic status and comprehensive utilization of tailings in China
(1) Basic status of tailings in China
There are 12,718 tailings ponds in China, of which 1,526 are tailings ponds under construction, accounting for 12% of the total, and 1024 tailings ponds have been closed, accounting for 8% of the total. As of 2007, the total tailings accumulation in China The amount is 8.046 billion tons. In 2007 alone, the national tailings discharge was nearly 1 billion tons. The massive stockpiling of tailings brings many problems such as resources, environment, safety and land:
Occupy land
Tailings need to occupy a large amount of land. As of 2005, China's tailings dumped more than 13 million acres of land. With the closure of the old tailings pond, the new tailings ponds will continue to increase, which will certainly occupy more land.
2. Waste resources
80% of China's mineral resources are associated with mines. Due to the late start of China's mining industry and unbalanced technological development, the gap between the selection and smelting technologies in different periods is very large, and a large number of valuable resources remain in the tailings. For example, iron ore tailings of China's total iron grade average of 8% to 12%, some even up to 27%. Based on the current total iron tailings stock of 4.5 billion tons, the tailings are equivalent to about 500 million tons of iron. The gold content in China's gold tailings is generally 0.2-0.6 g / ton, calculated based on the current total stock of 500 million tons, which still contains about 300 tons of gold. Non-metallic minerals in tailings are not only stockpiled, but some already have the potential characteristics of high value-added applications. As technology advances, its potential value will far exceed the value of metal elements. If these tailings resources cannot be recycled comprehensively, it will cause huge waste.
3. Environmental pollution
Some ore in the ore beneficiation process needs to be added, and these agents will remain in the tailings. The heavy metal ions contained in the tailings, and even pollutants such as arsenic and mercury , will flow into the nearby rivers with the tailings water or infiltrate into the ground, seriously polluting rivers and groundwater sources. The tailings after natural drying will form dust in the wind and blow to the surrounding areas, causing harm to the environment.
4. Security risks
Many tailings ponds are overdue or overloaded, and even operate in violation of regulations, making tailings inventory a great safety hazard, posing a serious threat to people's property and life safety in the surrounding areas. Since the founding of the People's Republic of China, there have been many dam failures in tailings reservoirs in China, causing a large number of casualties. In 2008, “9·8†Shanxi Xinxinta Mining Co., Ltd. tailings reservoir collapsed, causing more than 270 deaths, which is a blood lesson.
The comprehensive utilization of tailings is not only conducive to improving the comprehensive utilization of resources, reducing land occupation and protecting the environment, but also a fundamental solution to eliminate the safety hazards of tailings ponds.
(II) Comprehensive utilization of tailings in China
Tailings re-election
Re-election of tailings and recovery of valuable components from tailings are important measures to improve resource utilization. In recent years, due to the rapid increase in the price of metal ore products at home and abroad, the scale of China's tailings re-election has developed very rapidly. Some large-scale mining enterprises have carried out many explorations in the development of tailings re-election technology, which not only improves the resource recovery rate, but also brings huge economic benefits to the enterprise. However, at present, there are problems such as small scale, backward technology, low recovery rate, high energy consumption and high cost in the re-election of tailings in China. Due to the lack of unified planning and management, some even cause serious secondary pollution, or cause damage to the safety of tailings ponds.
2. Tailings production building materials
The main component of tailings is non-metallic minerals rich in resources such as SiO 2 , Al 2 O 3 , CaCO 3 , etc., and one or several building materials can be produced by existing mature processes. At present, there are some mature technologies for building materials for tailings production, but mainly draw on the mature technology already existing in the building materials industry, the original innovation is insufficient, the added value of products is low, the sales radius is small, and the production cost, transportation cost and product quality are not shown. Comprehensive advantages are difficult to promote on a large scale. Some tailings high-value utilization technologies, such as tailings preparation of glass-ceramics, ultra-durable tailings high-strength concrete technology, etc., have made breakthroughs in key technologies and processes, and are expected to become effective technologies for the large-scale utilization of tailings in the future.
3. Tailings are used to make fertilizer
Some tailings contain various trace elements required for plant growth, and can be made into trace element fertilizers for improving soil after proper treatment. In the 1990s, Maanshan Mine Research Institute added magnetized tailings to chemical fertilizers to make magnetized tailings compound fertilizer, and built a magnetized tailings compound fertilizer plant with an annual output of 10,000 tons, which turned the effect of turning waste into treasure. But these are only stuck in the use of a small amount of tailings, and can not reduce the accumulation of bulk tailings.
4. Filling mine goaf
Backfilling in mine goaf is one of the most effective ways to directly use tailings. Especially for mining enterprises that have no tailings storage, it is of greater environmental and economic significance to use tailings to backfill the goaf. The cement filling mining method is now a mature technology, which can increase the underground mining recovery rate by 20-50%, and the ore body below the water body, under the important traffic trunk line and under the residential area can be mined. The ideal cementation filling method can completely avoid surface subsidence and avoid major damage to the groundwater balance.
5. Tailings library reclamation
Reclamation of tailings ponds is an important measure to solve the surface desertification of tailings ponds. The reclamation of the tailings pond not only prevents the sand from rising, but also beautifies the environment and reduces pollution, and has both economic, social and environmental benefits. The tailings pond reclamation has explored an economical and feasible new way for the management of abandoned tailings ponds in China's mining enterprises.
(III) Problems in the comprehensive utilization of tailings in China
1. Low utilization of tailings
At present, most of China's tailings have not been comprehensively utilized, and the comprehensive utilization rate is less than 10%, especially the utilization rate of iron tailings and non-ferrous metal tailings is lower. With the continuous increase of mining resources in China, the discharge of tailings will increase every year, and it is urgent to accelerate the comprehensive utilization of tailings.
2. The basic work is weak and lacks data support
There is no basic data statistics on the comprehensive utilization of resources in China's economic development statistical system, and there is no data statistics on the comprehensive utilization of tailings. It is not conducive to the introduction of scientific policy measures, and it is not conducive to real-time adjustment of policy measures according to actual conditions. The technical standards system for tailings pollution prevention and control is not perfect, which hinders the effective development of relevant pollution control work.
3. Insufficient investment in tailings comprehensive utilization technology
At present, enterprises lack the motivation and enthusiasm to invest in the development of key technologies for the comprehensive utilization of tailings. At the same time, the country's investment in forward-looking technology development in the comprehensive utilization of tailings is insufficient, resulting in the majority of tailings comprehensive utilization technology only staying in simple and easy technology, lacking original technology that can make efficient use of tailings and large-value utilization. Research and development.
4. Insufficient support for existing policies
Although compared with the original mining and mining, the comprehensive utilization of tailings has good social benefits, but the resource quality is low, the utilization cost is high, and the economic benefits are poor. The existing comprehensive utilization policies for resources are not targeted, and the support is insufficient. The enthusiasm of enterprises to use tailings is not high.
Third, guiding ideology and development goals
