Use of the chrome (VI) oxide as a sorbent of arsenic from sour copper-containing solutions

In article results of clearing of copper electrolyte from arsenic with chromium (VI) oxide by using of stochastic and determinated design of experiment, at four levels are presented, optimum conditions of carrying out of process are defined. In addition, it was carried out mathematical processing of results and calculated correlation coefficients and their significance for private dependency of arsenic deposition powers, as in the article the image depending on the degree of deposition of arsenic from the studied factors derived generalized Protodyakonov's equation. The optimal process conditions: precipitant dosage rate 4; precipitant relation to an arsenic 2.5:1; process temperature 25 degrees C; concentration of sulfuric acid in electrolyte 200 g/l; time of the
