AbstractAbout AuthorsReferences
A possibility to expand the raw materials base for manufacturing magnesia binders and building materials due to the use of wastes of mineral processing plants and refractory produc- tions is considered. Methods for assessing the suitability of such wastes on the example of dumps of OAO «Grupp Magnezit», the city of Satka, adopted as a raw material have been developed and a methodological scheme of technology of binders production was proposed. The study includes fractioning of rocks and an analysis of their mineralogical composition with the help of X-ray phase and derivatographic analyses. Magnesites of the 3rd and 4th grade from the dumps of the plant are adopted as raw materials. As a result, features of the distribution of admixtures in rocks depending on the fraction composition was established; the technology of binder production, which includes the combined method of burning with the use of additive-intensifiers that makes it possible to exclude the presence of potentially harmful impurities, is proposed.
