Comprehensive Utilization of Sulfuric Acid Residue in Small Chemical Enterprise

Sulfuric acid residue is one kind of important secondary resource, its comprehensive utilization has drawn extensive attention. Based on analyzing the chemical composition of sulfuric acid residue, through comprehensive comparison of flotation, gravity separation, magnetized baking, magnetic separation and other joint technical processes, it is showed that the chemical-magnetic separation is reasonable by evaluating the applicable ability. Then introduced a case study on comprehensive utilization of sulfuric acid residue in Shikefeng chemical Co., LTD in Luzhou City, the duplex melting process combined advanced induction furnaces with smelting furnace was put forward. Finally, it's concluded that there are many advantages of the duplex melting process, it’s more suitable for the comprehensive utilization of sulfuric acid residue in small chemical enterprise.

Process Mineralogy

To identify the process mineralogical properties of kyanite from Heibei so as to provide a mineralogical basis for its chemical composition, mineral constituent，ores texture and structure and so on . The results show that: the kyanite Al2O3 21.50%, SiO2 52.87%, using high intensity magnetic separation —gravity separation— flotation folwsheet. Experiments show that, the grinding fineness of -0.074mm 65%, with strong intensity magnetic separation, magnetic concentrate by shaking the low intensity magnetic separation，we can get magnetite, garnet, biotite and phlogopite four concentrates, strong magnetic ore tailings consolidated by a rocking bed mud thrown first, refined through a coarse fine two shake, shake in after a rough featured a parted, won the 60.38% grade of Kyanite concentrate and 85% grade quartz ore.

Iron Bearing

A technology of “arsenic removing- sulfuric acid producing- residuals for ironmaking” is proposed for comprehensive utilization of pyrite with high content of arsenic. The effect of roasting temperature and time on arsenic removing was investigated. The arsenic removed residuals obtained under the optimal arsenic removed conditions, was used to be proceeded for sulphur volatilization test. The results demonstrate that final residuals with 63.53% of Fe can be used for steel industry. This technology can be used to fully utilize sulphur and produce high quality concentrate as iron-bearing feed for steel industry, which will help to reduce the pollution of arsenic and extend raw material sourcing for Chinese steel industry.
