Background
With the rapid development of social economy, the consumption of nonferrous metals in China is increased day by day, and many established mines and newly-discovered nonferrous resources are deep deposits, such as typical pyrite type copper deposits. During the mining process, on one hand, the underground gushing water passes through the surrounding environment of the ore deposit, and forms a large amount of acid water by the released oxysulfide through a series of chemical reactions and microbial catalysis; on the other hand, sulfide and water in the deposit contact with air, and natural oxidation reaction can occur. Further, under the condition of coexistence of a plurality of metal sulfide minerals, or when the internal crystal structure of the same mineral varies due to mixed crystals, impurities, defects, or the like, the difference in oxidation-reduction potential causes a galvanic discharge effect in a humid environment, and promotes dissolution of minerals or crystals having a low potential. Through the chemical reaction, an acidic water corrosion environment is promoted to be formed underground.
Generally, acidic water with a pH value of less than 6 has certain corrosivity on metal equipment, and the acidic water with a pH value of less than 4 has strong corrosivity, which causes serious harm to safe production and ecological environment of a mining area. The pH value of the wastewater of the deep mine is as low as 2.79-3.51, the wastewater belongs to a strong acid solution, the solution causes serious pollution to the surrounding ecological environment, and also generates great hidden dangers to the underground environment and the safety, and the method is embodied in the following aspects: the settling tank (1) corrodes underground steel rails, steel wire ropes and other transportation equipment. The strength of the steel plate can be greatly reduced, and transportation safety accidents can be caused; the air pump (2) quickly erodes the iron water control pipeline and the gate, under the condition of water flow flushing, the PH warning lamp (3) acid mine water interacts with certain components in the cement to generate hydrous sulfate crystals, and the salts expand in volume when generated, so that the concrete structure is loose in structure, and the strength is reduced and damaged. Meanwhile, the acidic mine water generally contains a large amount of Fe2+ and is colorless, and because the oxidation rate of Fe2+ can be obviously inhibited in an aqueous solution under an acidic condition, if the acidic mine water is slightly neutralized, reddish brown insoluble Fe (OH)3 precipitates can be generated, so that the environment is polluted.
The quality improvement of the sulfur concentrate becomes an important process for improving the quality of the sulfur concentrate, the traditional quality improvement process of the sulfur concentrate usually needs to firstly add sulfuric acid or other regulators to change the pH value of ore pulp, the use, management, transportation and the like of the sulfuric acid in the actual production process are inconvenient, equipment is easy to corrode, great potential safety hazards exist, a full-time responsible person needs to be arranged for management, and meanwhile, other regulators also need high medicament cost, so that the traditional method puts higher requirements on the environmental safety, personnel allocation, equipment maintenance and medicament consumption of enterprises.
