Crushers Increase the Use of Ore Resources One

Ore is China’s most important energy resources, its social and economic development play an extremely important role. Development and use of ore, both on plays a huge role in promoting socio-economic, but also had a significant impact on the environment. The development of ore gangue and ore-bed methane is the main waste generated in the process, the ore industry has long been regarded as hazardous substances and hazards of gas. Since the Third Plenum of the Eleventh Party, with the continuous deepening of economic reform and China’s healthy and rapid development of industry and agriculture, in the case of energy increasingly scarce, people gradually realized that these wastes are still available for the use of side. Particularly in the last 20 years, the ore sector in the development and utilization of ore gangue and ore-bed methane has done a lot of exploration and production test achieved a number of achievements.

Practice has proved that as long as the changing concepts, scientific research, according to local conditions attention to development and ore production in the process of secondary use of mineral resources is not only entirely feasible, but has great potential; not only of harm into turning waste into treasure, and can save energy, and get major social and economic benefits. ore gangue in the tunneling, mining and washing process of the solid waste discharges. Carbon quality, a mixture of clay and sandy shale, with low heat value. Carbon content of 20% ~ 30%, and some containing humic acid. China has accumulated over the years gangue about 1000Mt, and each year continues to emit about 100Mt, not only the accumulation of land, but also pollute the air or cause spontaneous combustion fire.

In recent years, with the various sectors of the comprehensive utilization of ore gangue awareness of the rapid rise of research, how to gangue turning waste into treasure? At home and abroad have been developed many ways to use. The basic principle is in identifying the nature of ore gangue based on the distinction so that the best use, and will use a variety of ways to combine the development of a certain scale and utilization system in order to get the best value for money. According to China’s actual conditions, its use generally has five areas:

As the professional manufacturer of complete sets of mining machinery, such as belt conveyor,rock crusher,China mobile crushers,China sand washers, Henan Hongxing is always doing the best in products and service.
