Evaluation terms definition and calculation process construction of mining recovery of solid non-energy mineral resources

Mining recovery is an important index to measure the exploitation and utilization of mineral resources.It is of great significance to accurately define the related evaluation terms and construct the calculation process of mining recovery,in order to formulate the national criteria of mining recovery of solid non-energy mineral resources in china.In this paper,the historical evolution of the mining recovery was summarized comprehensively and the type of mining recovery was identifiably analyzed.The terms of life (annual) evaluation mining recovery was defined and the calculation formula was determined through combining the evaluation work requirements.To meet the needs of mining recovery calculation under different mining methods,the synthetic method of mining recovery calculation was proposed based on the direct and indirect method.Take obtaining relevant data of mining recovery accurately as the main line,the calculation process of evaluation mining recovery was constructed in our country.The research achievements can provide important reference for macro-management of solid non-energy mineral resources in china.
