Resumo: | This research work was carried out with the aim of obtaining an alternative route for the leaching of low grade gold ores for an industrial plant which currently employs the Carbon in Leaching process in Uruguay. Bottle roll tests were performed in bottlers of 20 liters and columns of 3 meters to set some parameters, operating criteria and design that enables up the implementation of an industrial plant of leaching using dynamic stacks of up to 4 meters high to treat about 1,000,000 tons of low grade gold ore per year with an average gold content of 0.65 grams per ton of ore and operating with a particle size of 80 percent less than 12.67 mm. The operation time is 3 years reaching an annual output of 455 kilograms of gold.https://doi.org/10.18540/2446941602022016029 |

Diversos ensaios de lixiviação utilizando-se a técnica bottle roll test de 20 litros e colunas de 3 metros foram realizados visando-se estabelecer alguns parâmetros, critérios de operação e dimensionamento para avaliar um processo industrial de lixiviação para tratar cerca de 1.000.000 de toneladas de minério contendo cerca de 0,65 g de ouro por tonelada de minério (g/t). Foram concebidas pilhas de 4 metros de altura, minérios com uma granulometria 80% menor que 12,67 mm (P80 de 12,76mm), tempo de operação de 3 anos e atingindo-se uma produção anual de 455 quilogramas de ouro.Universidade Federal de Viçosa - UFV2016-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/244694160202201602910.18540/jcecvl2iss2pp029-041The Journal of Engineering and Exact Sciences; Vol. 2 No. 2 (2016); 029-041The Journal of Engineering and Exact Sciences; Vol. 2 Núm. 2 (2016); 029-041The Journal of Engineering and Exact Sciences; v. 2 n. 2 (2016); 029-0412527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941602022016029/pdfReyes Unda, Andrés GonzaloReyes, Carlos HugoCunha Lins, Vanessa de FreitasFerreira Rocha, Sonia Deniseinfo:eu-repo/semantics/openAccess2019-03-11T18:27:18Zoai:ojs.periodicos.ufv.br:article/2163Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2019-03-11T18:27:18The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false |
