Crusher Is Useful for Utilization of Metal Tailing
Posted Nov 22 2012 1:00am
With the strength of the exploitation of mineral resources in China, the discharging amount of the tailings will increase ever year. Therefore, accelerating the comprehensive utilization of the tailings is imminent. Currently, the vast majority of the tailings in our country have not been comprehensively used. The comprehensive utilization rate is less than 10%. Especially the utilization of iron ore tailings and non-ferrous metals tailings is low. Since unified planning and management is not enough, the stockpiling of the tailings can not be reasonably recycled. In addition, the tailings may cause the serious secondary pollution, which has extreme damage to the environment and the people around the environment. As we all know, compared to the solid waste such as fly ash, coal gangue and other metal tailings, the comprehensive utilization technology of the metal tailings is more complex and more difficult. As a result, vigorously developing the circular economy and improving the resource utilization have become the first problem to be solved for the metal mineral resources. The comprehensive utilization for processing the metal tailings has comprehensively put forward the basic status and comprehensive utilization of tailings, which provides a reliable guarantee for the comprehensive utilization of metallic tailings. In recent years, due to the rapidly rising prices of the metal mineral at home and abroad, the tailings scale development is very rapid. Some of the extra large mining enterprises have carried out a lot of researches in terms of the re-election technology development for the tailings, which has improved the resource recovery rate and brought huge economic benefits to the enterprise. However, the recycling work for the tailings still has the shortcomings of small scale, backward technology, low recovery rates, high energy consumption and high cost. This shows that increasing the technological innovation and research and development efforts, focusing on the development of a number of energy saving and environmental protection with independent intellectual property rights can stimulate enterprises to enhance their core competitiveness and promote the comprehensive utilization of resources. With the encourage and guide of the national policy, Henan Hongxing Mining Machinery has combined with the advanced production experience at home and abroad and has produced the environmental crusher machine with large crushing ratio, high efficiency and good quality.
