Embodiment example

[0014] Taking Chengde magnet tailings as an example, it is used as the material of pavement base and subbase, and the mixing ratio of each raw material (water is externally added):

[0015] Soil stabilizer 0.05%

[0016] Cement 5%

[0017] Magnet tailings powder 94%

[0018] Appropriate amount of water

[0019] With reference to the experimental methods of JTJG+E51-2009 and JTG E40-2007 of "Highway Engineering Inorganic Binder Stable Materials Test Regulations" and "Highway Soil Engineering Test Regulations" JTG E40-2007, the heavy-duty compaction test and unconfined compressive strength test of the pavement base material are carried out. The maximum dry density is 2.01g / cm3, the optimal water content is 7.0%, the test piece with a diameter of 50mm and a height of 50mm is produced, the compaction degree is controlled at 98%, and the standard unconfined compressive strength for 7 days is 2.5-3.6MPa , fully meet the road standards of high-grade highways.

Abstract

The invention discloses a method of processing magnet tailings by utilizing a soil curing agent. The method comprises following steps: evenly mixing the soil curing agent and magnet tailings, adding a proper amount of cementing material, controlling the mass percentages of the components as follows: 0.01 to 0.5% of soil curing agent, and 1 to 15% of cementing material, the balance being magnet tailings, and preparing the mixture mentioned above into a composite material. A recyclable composite material can be formed according to the method, can be applied to road construction and production of baking-free bricks, has the advantages of saving energy and protecting environment, and has important meanings on promoting technology innovation and structural adjustment of construction industry and traffic road building and transformation of economic growth pattern.

Description

technical field [0001] The invention relates to the technical field of tailings treatment, in particular to a method for treating magnet tailings with a soil curing agent. Background technique [0002] In recent years, the economy has developed rapidly, and the extensive mining mode and traditional technology have formed a large amount of tailings and occupied a large amount of land. Copper ions, lead ions, zinc ions, and even harmful substances such as arsenic and mercury, as well as chemicals added in mineral processing, will flow into nearby rivers or seep into the ground with mineral water, seriously polluting rivers and groundwater sources. The surface water flowing through the tailings storage site also interacts with the tailings to dissolve certain harmful components and transfer them, causing widespread pollution. The massive stockpiling of tailings has become a potential source of geological disasters and has become the biggest safety hazard in mining areas. In a...
