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

Technological parameters of opening refractory ores by mechanical activation which determine remaining and the morphology of the samples after mechanical activation, SHS synthesis and the leaching process has been defined. Mechano-chemical activation of arsenopirita in different modes increases process have been defined. Optimal conditions for activation: time - 30 min at a ratio of grinding media and mineral 2:1. Leaching rate was higher for the activated samples the same amount of time than the original. Extraction of gold for the chosen optimum conditions is 93.2-95%.
