Abstract: In order to improve the technical ability of each participant of mineral processing engineer⁃ ing in the whole life cycle of engineering construction and promote the digital，intelligent and high-quality development of the industry，the digital model construction and application research in the design，construc⁃ tion and operation stages are carried out for the digital construction and application of the whole process of mineral processing engineering.The research results show that the“one model to the end”mode of mineral processing engineering can effectively connect the stages of design，construction and operation，and realize the unified circulation and collaborative application of data and models through the process mechanism mod⁃ el，three-dimensional design model，construction model and operation and maintenance management mod⁃ el，so as to improve the efficiency of engineering construction and operation and reduce the engineering cost. The“one model to the end”mode can promote the data fusion and business collaboration of the whole life cy⁃ cle of the mineral processing project，which is the inevitable trend of the digital and intelligent transforma⁃ tion of the engineering construction of the concentrator.

Key words: model, BIM design, intelligent infrastructure, intelligent concentrator
