Example Embodiment

[0025] Example 1:

[0026] 1. The blast furnace slag taken from the Shaoguan Steelmaking Plant, whose basicity coefficient, activity coefficient and prime number coefficient are all in line with the national Class I quality, is pre-pulverized to a particle size of less than 200 mesh (74 microns).

[0027] 2. Take 1.3kg of the above-mentioned pulverized blast furnace slag, and 7.6kg of lead-zinc tailings from Qujiang Fankou, Shaoguan City, Guangdong Province, with 0.4kg of red mud produced by the sintering method of Zhengzhou Aluminum Plant and 0.5kg of weathered clay as auxiliary 0.1kg of phosphogypsum with a particle size of less than 45 microns is used as an activator, and 0.03kg of sodium lignosulfonate is used as a dispersant. First dissolve the dispersant in 1.2kg of water to be added, mix the dry powder and water with a horizontal coulter mixer or a high kneading mixer, mix evenly and pour into the mold, use a hydraulic brick machine to adjust the pressure to 20.0 Mpa, press...

Abstract

A method for using the S-enriched ore tailings to preparing the masonry material from S-enriched ore tailings sand slags of blast furnace, additive, trigger and disperser through dissolving disperser in water, proportionally adding others, stirring, and die pressing.

Description

[Affiliated technical field] [0001] The invention relates to an effective method for comprehensive utilization of sulfur-rich tailing sand, which belongs to the fields of environmental engineering and new building materials. [Background technique] [0002] Tailings are the discarded parts of ore after crushing, grinding and sorting. According to statistics, my country's current tailings storage capacity has reached 700 million cubic meters, and it is increasing at a rate of 7 to 8 million tons per year, occupying nearly 1,000 acres of land every year, and spending about 600 million yuan in processing costs. And with the continuous excavation of mines, the grade of mined ore is getting lower and lower, and the amount of tailings and corresponding investment will increase year by year. [0003] The tailings contain a variety of gangue minerals and useful elements, which are characterized by large quantities, concentration and fine particles. It is easy to lose when it encoun...
