Method for applying lithium ore leaching residues to building material industry

Abstract

The invention discloses a method for applying lithium ore leaching residues to the building material industry. The lithium ore leaching residues comprise, by weight, 200-400 parts of cement, 100-300 parts of lithium residues, 200-300 parts of water, 400-600 parts of coarse aggregate, 500-700 parts of fine aggregate, 20-50 parts of an accelerant, 30-70 parts of a curing agent and 10-30 parts of a water reducing agent, preferably 200 parts of the cement, 100 parts of the lithium residues, 200 parts of the water, 400 parts of the coarse aggregate, 500 parts of the fine aggregate, 20 parts of theaccelerant, 30 parts of the curing agent and 10 parts of the water reducing agent. Compared with the prior art, the preparation method has the beneficial effects that the preparation method is simple,pollution to the environment can be reduced, resources are reasonably utilized and the environment is effectively protected under the condition that material components meet the composite requirements, and the compressive strength and stability of concrete are greatly improved by adding the accelerant and the curing agent; and the pressure of environmental protection is reduced, good economic andsocial benefits are brought after digestion, the production cost of the concrete is reduced, the practicability is greatly improved, and great convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of lithium slag application, in particular to a method for applying lithium ore leaching slag in the building material industry. Background technique [0002] With the vigorous development of the construction industry, more and more construction waste has been piled up, and landfills are generally used for disposal. If the industry uses construction waste, it will protect the environment, promote sustainable economic development, and turn into a virtuous circle. my country is the country with the largest reserves of spodumene in the world. In the process of using sulfuric acid to produce lithium salt from spodumene, about 8-10 tons of acid lithium slag will be discharged when one ton of lithium salt is produced. According to this discharge rate, the amount of acid lithium slag produced in the production of lithium salts in my country is very large every year. A large-scale lithium carbonate and lithium hydro...

AI Technical Summary

Problems solved by technology

With the development of the lithium salt industry, the discharge of acid-process lithium slag is increasing day by day, and most of the waste produced by acid-process lithium slag is piled up and landfilled, resulting in waste of resources, polluting the environment, and causing geological environmental risks. Lithium carbonate slag ( Lithium slag (referred to as lithium slag) is the waste slag produced during the production of lithium carbonate by sulfuric acid method. For every 1 ton of lithium carbonate produced, 8 to 10 tons of lithium slag will be discharged. Lithium salt factories will discharge a large amount of lithium slag every year, occupying a large amount of land and polluting the environment. However, lithium slag The application effect in cement concrete is not ideal. Therefore, we provide a method for the application of lithium ore leaching slag in the building materials industry
