Data confidence 70 medium
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 results of investigations intended to create a process of joint manufacture of ferroalloys and nonferrous metals by an electrothermal method are presented. Thermodynamic simulation of the carbon reduction of Zn, Pb, Si, and Fe from a zinc-oligonite ore is used to determine the mechanism of reduction of zinc and lead with the formation of a ferroalloy after the distillation of zinc and lead and a complex use of the mineral part of the residue. An apparatus-technological scheme is proposed for the processing of zinclead-containing ores that cannot be beneficiated.
