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.
~ 70% of osmium passes into the mixture of process gases (mixture of electric furnace and converter gases) entering the sulfuric acid production, during the processing of sulfide copper raw materials.About 45-57 % of the isotope osmium-187 of its content in copper concentrate is concentrated in sulfuric acid wash at the extraction of rhenium.Tetraoxide of osmium (VIII) OsO4 is the most probable
