 <\/p>\n

Na lixivia\u00e7\u00e3o de ouro, a efici\u00eancia da recupera\u00e7\u00e3o metal\u00fargica depende da integra\u00e7\u00e3o entre diferentes etapas do processo. A pr\u00e9-alcaliniza\u00e7\u00e3o, a cianeta\u00e7\u00e3o e a adsor\u00e7\u00e3o em carv\u00e3o ativado trabalham em conjunto para garantir uma opera\u00e7\u00e3o est\u00e1vel, segura e com alto rendimento.<\/p>\n

Tradicionalmente, a etapa de pr\u00e9-alcaliniza\u00e7\u00e3o utiliza cal e outros reagentes para elevar o pH da polpa e criar as condi\u00e7\u00f5es ideais para a cianeta\u00e7\u00e3o. Embora essa pr\u00e1tica seja consolidada na minera\u00e7\u00e3o, a busca por solu\u00e7\u00f5es que aumentem a efici\u00eancia operacional, reduzam o consumo de reagentes e melhorem continuamente o desempenho da lixivia\u00e7\u00e3o faz parte da evolu\u00e7\u00e3o do setor.<\/p>\n

Nesse contexto, o ExtracTech surge como uma inova\u00e7\u00e3o desenvolvida para trazer ganhos ainda maiores comparado ao processo convencional. O biopol\u00edmero atua na etapa de pr\u00e9-alcaliniza\u00e7\u00e3o e pode ser dosado diretamente nos sistemas j\u00e1 existentes da planta, sem necessidade de altera\u00e7\u00f5es no circuito operacional.<\/p>\n

Entre os principais benef\u00edcios da tecnologia est\u00e3o a redu\u00e7\u00e3o de at\u00e9 35% no consumo de cianeto e o uso de at\u00e9 20 vezes menos agente alcalinizante, contribuindo para menores custos operacionais e uma lixivia\u00e7\u00e3o mais eficiente.<\/p>\n

No entanto, sempre que um novo reagente \u00e9 incorporado ao circuito, \u00e9 fundamental comprovar que sua utiliza\u00e7\u00e3o n\u00e3o compromete as etapas seguintes da recupera\u00e7\u00e3o de ouro. Uma das principais d\u00favidas entre as mineradoras, \u00e9 se o biopol\u00edmero pode interferir na cin\u00e9tica ou na efici\u00eancia da adsor\u00e7\u00e3o do ouro pelo carv\u00e3o ativado.<\/p>\n

Essa preocupa\u00e7\u00e3o \u00e9 comum porque muitos profissionais associam pol\u00edmeros a materiais viscosos, capazes de recobrir superf\u00edcies e, potencialmente, reduzir a capacidade de adsor\u00e7\u00e3o do carv\u00e3o.<\/p>\n

Para responder a essa quest\u00e3o, apresentamos os resultados de um estudo realizado para avaliar se a presen\u00e7a do biopol\u00edmero ExtracTech interfere na cin\u00e9tica ou na efici\u00eancia da adsor\u00e7\u00e3o de ouro pelo carv\u00e3o ativado, utilizando tanto carv\u00e3o ativado novo quanto carv\u00e3o regenerado.<\/p>\n

Como foi avaliada a influ\u00eancia do ExtracTech na adsor\u00e7\u00e3o pelo carv\u00e3o ativado<\/strong><\/h2>\n

Objetivo do estudo<\/strong><\/h3>\n

O objetivo do estudo foi provar que o ExtracTech ao ser utilizado como aditivo na lixivia\u00e7\u00e3o do ouro n\u00e3o apresenta impacto negativo sobre a cin\u00e9tica ou na efici\u00eancia da adsor\u00e7\u00e3o de ouro pelo carv\u00e3o ativado.<\/p>\n

Para isso, foram avaliadas duas condi\u00e7\u00f5es frequentemente encontradas nas opera\u00e7\u00f5es de minera\u00e7\u00e3o:<\/p>\n

    \n
  • Carv\u00e3o novo;<\/li>\n
  • Carv\u00e3o regenerado.<\/li>\n<\/ul>\n

    Como o teste foi realizado<\/strong><\/h3>\n

    Foi realizado o teste de cin\u00e9tica de adsor\u00e7\u00e3o de ouro utilizando uma solu\u00e7\u00e3o padr\u00e3o contendo 10 ppm de ouro, permitindo avaliar especificamente a intera\u00e7\u00e3o entre o ExtracTech e o carv\u00e3o ativado novo e o regenerado.<\/p>\n

    Cada condi\u00e7\u00e3o experimental foi realizada em duplicata, totalizando:<\/p>\n

      \n
    • 2 testes do sistema controle (Tal Qual);<\/li>\n
    • 2 testes utilizando ExtracTech.<\/li>\n<\/ul>\n

      Os resultados apresentados neste artigo correspondem \u00e0 m\u00e9dia dos ensaios.<\/p>\n

      As principais condi\u00e7\u00f5es experimentais foram:<\/p>\n

        \n
      • Solu\u00e7\u00e3o padr\u00e3o contendo 10 ppm de ouro;<\/li>\n
      • Volume de solu\u00e7\u00e3o: 1 litro;<\/li>\n
      • pH de aproximadamente 10,2;<\/li>\n
      • Concentra\u00e7\u00e3o de 240 ppm de NaCN;<\/li>\n
      • Agita\u00e7\u00e3o cont\u00ednua;<\/li>\n
      • Amostragens ap\u00f3s 1, 2, 4, 8, 16 e 24 horas.<\/li>\n<\/ul>\n

        Durante o estudo foram avaliados:<\/p>\n

          \n
        • A cin\u00e9tica de adsor\u00e7\u00e3o do ouro;<\/li>\n
        • A efici\u00eancia de adsor\u00e7\u00e3o.<\/li>\n<\/ul>\n

          Resultados utilizando carv\u00e3o ativado novo<\/strong><\/h2>\n

          A primeira etapa da avalia\u00e7\u00e3o foi realizada utilizando carv\u00e3o ativado novo.<\/p>\n

          Os resultados mostraram que a presen\u00e7a do ExtracTech n\u00e3o alterou a cin\u00e9tica de adsor\u00e7\u00e3o do ouro em rela\u00e7\u00e3o ao sistema controle. Desde a primeira hora de avalia\u00e7\u00e3o, ambos os sistemas apresentaram efici\u00eancia de adsor\u00e7\u00e3o superior a 94%, ultrapassando 99% ao final do estudo.<\/p>\n

           <\/p>\n

          Os resultados demonstram que a presen\u00e7a do ExtracTech n\u00e3o compromete a adsor\u00e7\u00e3o do ouro pelo carv\u00e3o ativado.<\/p>\n

          Ao contr\u00e1rio, durante toda a avalia\u00e7\u00e3o, o sistema contendo o biopol\u00edmero apresentou percentuais de adsor\u00e7\u00e3o iguais ou superiores aos do sistema controle, alcan\u00e7ando 100% de adsor\u00e7\u00e3o ao final do teste.<\/p>\n

          Resultados utilizando carv\u00e3o regenerado<\/strong><\/h2>\n

          Na segunda etapa do estudo, a mesma metodologia foi aplicada utilizando carv\u00e3o regenerado, condi\u00e7\u00e3o amplamente utilizada em opera\u00e7\u00f5es industriais.<\/p>\n

          Assim como observado com o carv\u00e3o ativado novo, a presen\u00e7a do ExtracTech apresentou comportamento equivalente ao sistema controle durante toda a avalia\u00e7\u00e3o.<\/p>\n

          Embora pequenas diferen\u00e7as tenham sido observadas entre alguns pontos de amostragem, elas permaneceram dentro da variabilidade esperada para esse tipo de avalia\u00e7\u00e3o.<\/p>\n

          Conforme registrado no relat\u00f3rio t\u00e9cnico, um dos ensaios apresentou um comportamento pontual fora da tend\u00eancia nas primeiras amostragens, atribu\u00eddo \u00e0 variabilidade anal\u00edtica ou de amostragem, sem rela\u00e7\u00e3o com a presen\u00e7a do biopol\u00edmero.<\/p>\n

          Mesmo diante dessa variabilidade, o sistema contendo ExtracTech manteve desempenho consistente durante toda a avalia\u00e7\u00e3o e apresentou resultados equivalentes ou superiores ao sistema controle, encerrando o teste com um percentual m\u00e9dio de adsor\u00e7\u00e3o de 74,08%, frente a 68,00% do controle.<\/p>\n

          Esses resultados demonstram que al\u00e9m do biopol\u00edmero n\u00e3o interferir negativamente na cin\u00e9tica de adsor\u00e7\u00e3o, ainda tem-se um ganho na cin\u00e9tica e recupera\u00e7\u00e3o metal\u00fargica ao final das horas de lixivia\u00e7\u00e3o.<\/p>\n

          O que os resultados demonstram?<\/strong><\/h2>\n

          Os resultados respondem de forma objetiva \u00e0 principal d\u00favida relacionada ao uso do ExtracTech na lixivia\u00e7\u00e3o de ouro: o biopol\u00edmero n\u00e3o interfere negativamente na cin\u00e9tica de adsor\u00e7\u00e3o do ouro pelo carv\u00e3o ativado.<\/p>\n

          Nos testes realizados com carv\u00e3o ativado novo, o sistema contendo ExtracTech apresentou percentuais de adsor\u00e7\u00e3o iguais ou ligeiramente superiores aos do sistema controle em todos os pontos avaliados, alcan\u00e7ando 100% de adsor\u00e7\u00e3o ao final do estudo.<\/p>\n

          Nos testes com carv\u00e3o regenerado, o comportamento foi igualmente consistente. Apesar da variabilidade esperada para esse tipo de avalia\u00e7\u00e3o, o sistema contendo o biopol\u00edmero manteve desempenho equivalente ou ligeiramente superior ao controle durante o estudo e encerrou a avalia\u00e7\u00e3o com um percentual m\u00e9dio de adsor\u00e7\u00e3o em torno de 6% superior ao observado no sistema controle.<\/p>\n

          Em conjunto, esses resultados demonstram que o ExtracTech preserva a efici\u00eancia da adsor\u00e7\u00e3o pelo carv\u00e3o ativado e, nas condi\u00e7\u00f5es avaliadas, apresentou desempenho equivalente ou ligeiramente superior ao sistema convencional. Dessa forma, o estudo confirma que o biopol\u00edmero pode ser incorporado ao circuito de lixivia\u00e7\u00e3o sem comprometer uma das etapas mais importantes.<\/p>\n

          Conclus\u00e3o<\/strong><\/h2>\n

          Os testes realizados demonstram que o ExtracTech pode ser utilizado na etapa de lixivia\u00e7\u00e3o sem comprometer a cin\u00e9tica ou a efici\u00eancia da adsor\u00e7\u00e3o de ouro pelo carv\u00e3o ativado.<\/p>\n

          Tanto nos estudos conduzidos com carv\u00e3o novo quanto com carv\u00e3o regenerado, o biopol\u00edmero apresentou desempenho equivalente ao sistema controle, confirmando que sua presen\u00e7a n\u00e3o interfere negativamente na capacidade de adsor\u00e7\u00e3o do carv\u00e3o.<\/p>\n

          Essa evid\u00eancia t\u00e9cnica refor\u00e7a a compatibilidade do ExtracTech com processos de lixivia\u00e7\u00e3o que utilizam carv\u00e3o ativado para recupera\u00e7\u00e3o de ouro, permitindo que as opera\u00e7\u00f5es aproveitem os benef\u00edcios da tecnologia, como a redu\u00e7\u00e3o de at\u00e9 35% no consumo de cianeto e o uso de at\u00e9 20 vezes menos agente alcalinizante, sem comprometer o desempenho da etapa de adsor\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
