Abstract：The metallogenic condition is favorable and the mineral resources are abundant in Qimantage ore concentration area of Qinghai Province. In order to provide technical support for development of resources optimization in ore concentration area, the authors have made the exploitability evaluation for partial mineral resources in ore concentration area by exploitability grading. The specific research methods are as following: Firstly, based on the beneficiation recovery rate, the exploitability grade evaluation has been established for different minerals and different areas. Secondly, the “correction value of beneficiation recovery rate” has been calculated according to beneficiation recovery rate in mine site. Then the exploitability grade of useful minerals in mine has been identified compared with the correspond exploitability evaluation grade. Finally, the exploitability grade of the mine has been identified based on the exploitability grade of useful minerals. The results show that the easy available grade accounted for 40.00% and the medium available grade accounted for 26.67%. Besides the grade difficult to use accounted for 33.33% in the 15 mines (deposits) of Qimantage ore concentration area. The research results could provide some reference in the management and development optimization for government mining department.
