Abstract Resources and environmental impact of pyrometalluryical separation process of paigeite ore were studied with AT&T Matrix System Evaluation Method. Through resources characterization of this process, the AT&T matrix evaluation objects were improved that means PLCA、TLCA、FLCA for pyrometallurgical separation process of paigeite ore, should be evaluated respectively with AT&T matrix and some recommendations were put forward. At the same time was a factor (stage)environmental effect legend was outlined. The results showed, that resourceful use of pyrometallurgical separation process of paigeite ore demonstrate an idea of comprehensive utilization of boron and other elements for environmental management. Active building FLCA ecological industrial park with pyrometallurgical separation process of paigeite ore is one of the effective measures to reduce consumption of resources and environment burden. It is pointed out that the attention should be paid to the balance of economical benefits and environment protection during decision making of ecoindustrial park.
