<i />Processing of iron-containing waste by the method of microbiological destruction in order to obtain iron oxide pigment
Studies on the use of the method of microbiological destruction by culture of thioniciron-oxidizing bacteria for the processing of iron-containing waste: black metal scrap are presented. During the processing of iron-containing waste, iron-oxide pigments of various shades were obtained. To increase economic efficiency and reduce environmental impacts, it is proposed to regenerate waste bio-solutions for their reuse.
