How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The scientific results of the optimization of raw materials mixtures for the production of cement clinker with the involvement as a secondary raw material – technogenic waste of the enrichment of non-ferrous metal ores, which by their chemical composition are of interest as an iron-aluminum-silicate raw material component. It has been established that the use of non-ferrous metal ore enrichment waste in the raw material mixture in the form of secondary technogenic raw materials contributes to its utilization, reducing the specific fuel consumption during clinker firing by 5.76%, reducing the firing temperature by 50 °C and obtaining cement clinker that meets the requirements for chemical and mineralogical compositions according to GOST 31108-2016.
