【摘要】：利用不同促释方法对电解锰渣(EMR)中有效硅进行活化,以实现锰渣资源化利用。通过微波焙烧活化、机械球磨及机械复合3种不同方式,考察各方法对硅活化的作用,探索适合锰渣活化的方式,揭示相关活化机理。结果表明,经3种不同方式活化后,锰渣中有效硅含量均得到提高,机械复合活化的方式最好,在球磨时间为40 min,微波焙烧温度为900℃、m(EMR)/m(Na2CO3)=1∶0.6、焙烧时间为40 min时,采用该方式锰渣中有效硅含量可达16.37%。
[Abstract]:The effective silicon in electrolytic manganese slag EMRs was activated by different releasing methods to realize the utilization of manganese slag. Through microwave roasting activation, mechanical milling and mechanical recombination, the effects of different methods on silicon activation were investigated, and the suitable ways for manganese slag activation were explored, and the related activation mechanism was revealed. The results showed that the content of available silicon in manganese slag was increased after activation in three different ways, and the best way of mechanical composite activation was obtained. When the milling time was 40 min, the microwave calcination temperature was 900 鈩，
