摘要： The present disclosure provides a method for treating Cr-containing pickling sludge in a slag bath, including the following steps: 1, adding a reducing agent, lime and a fluxing agent to the Cr-containing pickling sludge and fully mixing; 2, pelletizing the mixture by using a pelletizer and drying at a certain temperature; 3, putting the dried sludge pellets from step (2) into the high-temperature metallurgical slag for a slag bath reaction; and 4, subjecting cooled slag to crushing, screening and magnetic separation, thus separating out metal particles. Under the conditions of this method, the Cr-containing pickling sludge is thoroughly reduced and detoxified by using the high-temperature metallurgical slag so that most of sulfur in the sludge is immobilized in the slag phase. No secondary pollution is caused during the process and valuable metal elements such as Cr and Fe in the high-temperature slag and the sludge can be fully reduced to the metal phase and then recovered by magnetic separation. The treatment method provided in the present disclosure is simple to operate and can be implemented during a steelmaking process without secondary emission. Thus, online recycling and emission reduction at source of the Cr-containing pickling sludge are actually realized.

摘要： The invention belongs to the field of high value utilization of secondary resources, in particular to a method for preparing zeolite 4A from tailings and its application. The synthetic steps of zeolite 4A are as follows: high temperature alkali melting of sodium carbonate, aging with water, heating crystallization, washing and drying. When tailings are used as raw materials, Al (OH) 3 should be added before alkali melting at high temperature to form zeolite in the process of alkali melting to synthesize NaAlSiO4. The results showed that the optimum pH range was 4-8, the treatment time was within 10s, the treatment effect reached the national discharge standard, and the adsorption capacity was 150mg / G-200 mg/g. The zeolite can be reused after treatment. The overall recovery rate is more than 90%, in which the recovery rate of the first time is more than 92% and the second time is more than 93%. The beneficial effect of the invention is to use high silicon tailings to synthesize zeolite, which realizes high value utilization of tailings secondary resources. Comprehensive utilization of tailings not only solves environmental problems but also creates huge economic benefits from preparation of zeolite 4A. -1/5 Goldflotation gs Lead containing wastewater Ranlminlgrmding A1(OH)3,Na2CO3 Ion enge reacin High-temperature alkalimeltinn filter Essence I wastewater Water aging molecular siev Heating and crystallization Waing|and Molecularsieveaanasyhi dryingfilter zPeolite 4A molecular Filtering wastewaterNa Dry : Pb pre cipitat on reacti on Rccemolecular sieve and Filter and recover Pb S r1 eusye t recover bS Fig. 1
