Embodiment 1

[0032] A method for preparing dry powder mortar with gravity separation tailings of lead-zinc ore, specifically comprising the following steps:

[0033] Step 1, taking inorganic gelling material, filler, gravity separation tailings of lead-zinc ore, additives and water in proportion as raw materials, and set aside;

[0034] Step 2. Divide the weighed raw materials into two components A and B according to the mass ratio of 4.5:1, fully mix the inorganic gelling material, filler and zinc oxide rotary kiln tailings in component A to prepare the mortar base , Dissolve the additive in component A in water to prepare an additive aqueous solution, put the mortar base material into the mixer, add the additive aqueous solution while stirring, add component B after stirring evenly, stand still and dry in the air after stirring again, Promptly make described mortar;

[0035] Step 3: Dry the mortar prepared in Step 2 and transfer it to storage equipment or packaging equipment for storage...

Embodiment 2

[0037] In some embodiments, the preparation method of the tailings from the gravity separation of the lead-zinc oxide ore includes firstly mixing the lead-zinc oxide ore with a catalyst, then pulverizing and roasting in a rotary kiln, and then collecting the residual residue. Wherein, the lead-zinc oxide ore is mixed with the catalyst and crushed until the particle size is less than or equal to 6mm, the catalyst is sodium chloride, and the mass ratio of the catalyst to the lead-zinc oxide ore is 1:20.

Embodiment 3

[0039] In some embodiments, the preparation method of the tailings from the gravity separation of the lead-zinc oxide ore includes firstly mixing the lead-zinc oxide ore with a catalyst, then pulverizing and roasting in a rotary kiln, and then collecting the residual residue. Wherein, the lead-zinc oxide ore is mixed with the catalyst and crushed until the particle size is less than or equal to 6mm, the catalyst is sodium sulfate, and the mass ratio of the catalyst to the lead-zinc oxide ore is 1:30.

Abstract

The embodiment of the present invention discloses a method for preparing dry-powder mortar by using lead and zinc oxide ore re-selecting tailings. The method comprises the following steps: firstly, inorganic cementitious materials, fillers and lead and zinc oxide ore re-selecting tailings are mixed in proportions; then the mixture is put into a stirrer to be stirred; during the stirring, an additive and water are added at the same time to prepare mortar; and the mortar is air-dried to prepare the dry-powder mortar. In the provided method for preparing the dry-powder mortar by using the lead and zinc oxide ore re-selecting tailings in the embodiment of the present invention, the lead and zinc oxide ore re-selecting tailings are used as the raw materials for the dry-powder mortar; the methodeffectively solves a problem of resource waste brought by the lead and zinc oxide ore re-selecting process and can also effectively solve the pollution problem; in addition, the lead and zinc oxide ore re-selecting tailings are used as the raw materials for the dry-powder mortar and combined with other accessory materials; and the method can greatly improve the strength of the existing dry-powdermortar and can also improve the uniformity degree of the dry-powder mortar.

Description

technical field [0001] The embodiment of the present invention relates to the field of building materials, in particular to a method for preparing dry powder mortar by using the gravity separation tailings of lead-zinc oxide ore. Background technique [0002] Dry powder mortar refers to a kind of granular or powder form which is physically mixed with dry and screened aggregates, inorganic gelling materials and additives in a certain proportion. It is transported to the construction site in bags or in bulk, and mixed with water. materials that can be used directly. Also known as mortar dry powder, dry mix, dry mix powder, some construction adhesives also belong to this category. Dry powder mortar plays the role of bonding, padding, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. [0003] my country is rich in lead-zinc mineral resources, among which the basic reserves of lead reach 12.84 m...
