Embodiment 1

[0015] The invention discloses a new type of ore powder prepared by neutralizing slag from industrial waste slag, which is composed of the following mass percentages: 90% of neutralizing slag, 10% of nickel slag, waste slag discharged from rare earth enterprises producing rare earth products, The nickel slag is the waste slag discharged from nickel product enterprises after producing nickel products; wherein, the neutralization slag contains CaO, SiO 2 、Al 2 o 3 , Fe 2 o 3 , MgO and H 2 O, the water content is 60%.

[0016] The invention discloses a method for preparing a new type of ore powder by neutralizing slag from industrial waste slag. The neutralization slag and nickel slag are calculated as 90% neutralization slag and 10% nickel slag by mass percentage, and are mixed and stirred evenly by equipment to carry out hydration reaction. , and then dried in a drying kiln at 100°C to form a new type of mineral powder product with a new mineral composition and a new cryst...

Embodiment 2

[0019] The invention discloses a new type of ore powder prepared by neutralizing slag from industrial waste slag, which is composed of the following mass percentages: 95% of neutralizing slag, 5% of nickel slag, the waste slag discharged from rare earth enterprises producing rare earth products, The nickel slag is the waste slag discharged from nickel product enterprises after producing nickel products; wherein, the neutralization slag contains CaO, SiO 2 、Al 2 o 3 , Fe 2 o 3 , MgO and H 2 O, the water content is 60%.

[0020] The invention discloses a method for preparing a new type of ore powder by neutralizing slag from industrial waste slag. The neutralization slag and nickel slag are calculated as 95% of neutralization slag and 5% of nickel slag according to the mass percentage, and are mixed and stirred evenly by equipment to carry out hydration reaction. , and then dried in a drying kiln at 300°C to form a new type of mineral powder product with a new mineral compo...

Abstract

The invention discloses novel mineral powder prepared from industrial waste residue neutralizing slag and a preparation method of the novel mineral powder. The novel mineral powder comprises the steps: according to the weight percentage, uniformly mixing and stirring 90-95% of neutralizing slag and 5-10% of nickel slag are through equipment; carrying out hydration reaction, and drying in a dryingkiln at the temperature of 100-300 DEG C to form a novel mineral powder product with new hydrated mineral composition and new active crystal lattices and with water content of less than 1.0%; and mechanically grinding the novel mineral powder product material into a powdery novel mineral powder product. The novel mineral powder product can replace natural cement clinker to be used for producing cement and concrete, the replacement amount is 40-50%, electricity is saved by 50% for mineral powder enterprises, the machine-hour yield is increased by 50%, a new technical process is provided for neutralizing slag treatment, mineral resources are saved, the emission amount of carbon components is reduced, and the ecological environment is protected against secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of resource-based new technology materials, and in particular relates to the production of new mineral powder by using industrial waste slag neutralized slag and a preparation method thereof. Background technique [0002] The composition of the neutralization slag is complex. It is a waste residue like white mud discharged from the rare earth production enterprises. , contains trace amounts of toxic and harmful substances, and it is very difficult to develop and utilize. At present, this kind of waste is basically disposed of by landfill, which seriously pollutes the environment. If it continues like this for a long time, it will cause great harm to human health. Under the new situation of taking the scientific outlook on development as the goal and promoting the construction of a harmonious society based on people, harmlessness and resource utilization are urgent problems that must be solved by those skille...
