Resumo: A sulfate solution containing 1773.965 mg/L Mn2+, 3216.178 mg/L Mg2+ and 566.254 mg/L Ca2+ was used to perform the maximum recovery of manganese and minimum recovery of magnesium. Carbonate precipitation was used due to the better selectivity for manganese over magnesium and other impurities recovery compared to hydroxide precipitation. Four factors were studied: solution pH value, contact time, reaction temperature and sodium carbonate consumption. Analysis of variance (ANOVA) and response surface methodology (RSM) were used to determine the optimum. Under the optimum conditions, the manganese and magnesium recoveries were the highest and the lowest respectively, while the pH, the time, the temperature and the volume of Na2CO3 were the lowest.  The values of the four factors were found as followed: 8.9293, 60.69 min, 77.95°F, and 50.7650 mL respectively. Moreover, the recoveries of manganese and magnesium were 99.9799% and 4.3045% respectively. The results show that optimization using RSM is effective in improving carbonate precipitation of manganese.

Se utilizó una precipitación de carbonato debido a la mayor selectividad de manganês o magnesio y a la recuperación de otras impurezas en comparación con la precipitación de hidróxido. Se estudiaron cuatro factores: valor de pH de la solución, tiempo de contacto, temperatura de reacción y consumo de carbonato de sodio. Análisis de varianza (ANOVA) y metodología de superficie de respuesta (RSM) del foram utilizado para determinar el óptimo. Las condiciones óptimas, la recuperación de manganés y magnesio para los niveles más alto y más bajo, respectivamente, en términos de pH o tiempo, a la temperatura o volumen más bajo de Na2CO3. Los valores de dos cuatro factores foraminíferos se encuentran de la siguiente manera: 8.9293, 60.69 min, 77.95 ° F y 50.7650 mL, respectivamente. Además, las recuperaciones de manganés y foram de magnesio de 99,9799% y 4,3045%, respectivamente. Los resultados muestran que la optimización con RSM es eficaz para derretir la precipitación del carbonato de manganés.Uma solução de sulfato contendo 1773,965 mg/L Mn2+, 3216,178 mg/L Mg2+ e 566,254 mg/L Ca2+ foi usada para realizar a recuperação máxima de manganês e a recuperação mínima de magnésio. A precipitação de carbonato foi usada devido à melhor seletividade do manganês sobre o magnésio e a recuperação de outras impurezas em comparação com a precipitação de hidróxido. Quatro fatores foram estudados: valor do pH da solução, tempo de contato, temperatura de reação e consumo de carbonato de sódio. Análise de variância (ANOVA) e metodologia de superfície de resposta (RSM) foram usadas para determinar o ótimo. Nas condições ótimas, as recuperações de manganês e magnésio foram as mais altas e as mais baixas, respectivamente, enquanto o pH, o tempo, a temperatura e o volume de Na2CO3 foram os mais baixos. Os valores dos quatro fatores foram encontrados da seguinte forma: 8,9293, 60,69 min, 77,95°F e 50,7650 mL, respectivamente. Além disso, as recuperações de manganês e magnésio foram de 99,9799% e 4,3045%, respectivamente. Os resultados mostram que a otimização usando RSM é eficaz na melhoria da precipitação de carbonato de manganês.Universidade Federal de Viçosa - UFV2021-06-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1263210.18540/jcecvl7iss3pp12632-01-22eThe Journal of Engineering and Exact Sciences; Vol. 7 No. 3 (2021); 12632-01-22eThe Journal of Engineering and Exact Sciences; Vol. 7 Núm. 3 (2021); 12632-01-22eThe Journal of Engineering and Exact Sciences; v. 7 n. 3 (2021); 12632-01-22e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/12632/6668Copyright (c) 2021 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMuanda, Meschack Mukunga Omalanga, Pele Pascal Daniel2021-08-16T18:50:11Zoai:ojs.periodicos.ufv.br:article/12632Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-08-16T18:50:11The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
