Abstract: Gold production has the characteristics of high value, high cost, high pollution and high emission. The greening of the gold industry is of great significance to sustainable development. The ore content of gold ore is low, and a large number of tailings will be produced during the production process. These tailings occupy a lot of land and cause huge environmental burdens. Therefore, the resource utilization of gold tailings is of great significance. Gold tailings are rich in silicon, and the tailings have fine particles and potential pozzolanic activity. Using gold tailings to produce cement concrete is an ideal way to realize the utilization of tailings as building materials. This paper theoretically analyzes the possibility of using gold tailings to prepare cement clinker, mortar and concrete products from the aspects of physical-chemical properties, particle characteristics and macroscopic particle group properties of gold tailings, and summarizes the use of gold at home and abroad. The research progress of tailings production of cement and mortar concrete aims to provide reference for the efficient utilization of gold tailings as building materials resources and related research.

Key words: gold tailing, cement-based material, cement clinker, aggregate, mineral admixture, building material utilization
