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 aim of the research is the selection and justification of the combined gravity method of enrichment of refractory gold-bearing raw materials and the hydro and pyrometallurgical method of processing enrichment products based on the study of the technological properties of the feedstock and enrichment products in the mineral and raw materials complex of the deposit located on the territory of the Republic of Kazakhstan. There is a tendency to increase the imbalance between mining and also the increase in off-balance reserves of gold-bearing ores, which ultimately poses a serious problem for the development of the country’s economy. Research on the development of technology for the extraction of gold from refractory ores has been performed on three samples of the Vasilkovsky stockwork deposit. The ores are persistent in the presence of arsenic (arsenopyrite) and finely divided gold, a significant part of which is in the form associated with both sulfides (mainly arsenopyrite) and rockforming minerals.
