Our country has rich rare earth resource, and is the rare earth production, export and consumption of power. Rare earth separation process generates wastes pollution is serious with each passing day, and the rare earth industry development reality, environmental protection and development trend of rare earth oxide extraction cleaning requirements, only the solution of rare earth smelting process of three wastes" pollution of the environment problem, reduce the unit consumption of products and raise the comprehensive utilization rate of resources, rare earth enterprises to sustainable development. Cleaner production found economic development and environmental protection the combination of cleaner production, pay attention to improving energy efficiency, from the source of pollutants abatement, to achieve environmental protection and economic benefit, is the rare earth enterprises to achieve sustainable development of the route one must take. The Rare Earth Smelter problems and status in Baotou City, a rare earth smelter in preparation of high pure rare earth oxide production technology for clean production technology of. Solving process of various chemical materials recycling and comprehensive utilization of the problems, the introduction of cleaner production technology, to achieve energy-saving emission reduction, abatement efficiency purposes. The main research results include:1)The analysis pointed out that the domestic industry of cleaner production the problem of existence is the rare earth enterprises to implement cleaner production enthusiasm is not high, the reason depends on existing environmental law enforcement is not enough, the lack of supporting tax preferential policies, resource pricing and charging unreasonable; two is the enterprise clean production scheme obtained method is limited, because the material balance and waste generation analysis of causes to was not caused enough take seriously; three is the rare earth enterprise implementation of cleaner production for short, is currently on the rare earth of cleaner production information, technical support rarely, cleaner production assessment and incentive mechanism is not effective to carry out.2)Summarize audit experience, put forward to guarantee success of rare earth enterprises to carry out cleaner production measures, namely plusStrong advocacy leadership support, strive for full participation in a variety of ways; for clean production plan, material balance and waste seriously causes analysis; improve the cean production work incentive mechanism, make sustainable cleaner production audit.
