Abstract

The invention discloses a mine filling cementing material as well as a preparation method and application thereof. The mine filling cementing material is composed of lead-zinc ore smelting waste residues, lead-zinc ore tailings and an alkali activator. The invention also discloses a mine filling material containing the mine filling cementing material. According to the method for producing the cementing filling cementing material for the mine by utilizing the smelting solid waste slag of the lead-zinc ore and the tailings in the mining process, the performance of the cementing filling cementingmaterial can completely meet the requirements of mine filling, and the cementing filling cementing material plays a positive role in effectively utilizing the solid waste of the lead-zinc ore at present.

Description

technical field [0001] The invention relates to the technical field of mine filling, in particular to a mine filling cementing material and its preparation method and application. Background technique [0002] Lead and zinc are indispensable and important metal elements in the process of national economic development, and are widely used in human life and industrial production. The scale and number of lead-zinc smelting enterprises in my country are expanding year by year, smelting technology has made important progress, and the lead-zinc smelting industry has developed rapidly. Due to the complexity of the lead-zinc smelting process, a large amount of harmful substances such as waste gas, waste water and waste slag are produced, causing serious pollution to the environment. The amount of smelting waste slag produced in my country in 2010 was about 315 million tons, of which only the lead-zinc smelting slag was generated. The volume reached 4.3 million tons. [0003] The tr...
