Problems solved by technology

[0005] In the current technology, the production of polyaluminum chloride water purifier will produce water purifier slag, the production of high-activity aluminum hydroxide will produce sodium aluminate slag, and the production of accelerator will produce accelerator slag. If these residues are not recycled Direct discharge will not only pollute the environment, but also waste resources

Abstract

The invention discloses a process and a production line for preparing a tailing functional material. The process is characterized by comprising the steps: taking and mixing 10 to 30 parts by weight ofpolyaluminum chloride water purifying agent slag, 20 to 50 parts by weight of accelerator slag and 20 to 50 parts by weight of sodium aluminate slag; then drying the mixture until 5 to 10 parts by weight of water is evaporated; transferring to a dryer for drying, and then transferring to a mixer; then adding 3 to 6 parts by weight of organic alcohol amine and 1 to 2 parts of stabilizer to the mixer to stir to obtain a tailing functional material. The tailing functional material can specially serve as an additive for various tailings of mines to improve the activity of tailing fine powder as aconcrete admixture, a cement admixture and a mortar additive at different degrees to improve the performance of the tailing fine powder material. According to the invention, the three waste materialsare fully utilized, waste is changed into treasure, a disadvantage is turned into an advantage, pollution can be controlled, the environment can be improved, occupied land resources are released, andgood economic benefits are realized.

Description

technical field [0001] The invention relates to the field of waste recycling, in particular to a process and production line for preparing tailings functional materials. Background technique [0002] Polyaluminum chloride: alias polyaluminum, polyaluminum, molecular formula [Al2(OH)nCl6-n.XH2O]m or [Al2(OH)nCl6-n]m, (m≤10;n≤5), is A new type of high-efficiency inorganic polymer flocculant, its aqueous solution is a hydrolysis product between aluminum trichloride and aluminum hydroxide, with colloidal charge, so it has strong adsorption to suspended solids in water, so as to achieve coagulation The purpose of suspended solids in water. It is used in metallurgy, electric power, tanning, medicine, printing and dyeing, papermaking, chemical industry and other sewage treatment industries. Its coagulation effect forms flocs (also known as alum flowers) quickly, and the particles are large and heavy, and settle quickly. The applicable pH range is between 5 and 9. It has the chara...
