Abstract

"MéTODO E PLANTA PARA TRATAMENTO TéRMICO DE MINéRIOS SULFìDICOS USANDO UM LEITO FLUIDIZADO ANULAR". A presente invenção refere-se a um método e a uma planta para o tratamento térmico de minérios sulfídicos, em que sólidos são aquecidos até uma temperatura de aproximadamente 450 a 1500 <198>C em um reator de leito fluidizado (1). De modo a se melhorar a utilização de energia, é proposto introduzir um primeiro gás ou uma mistura de gás a partir de baixo através de um tubo de suprimento de gás (3) para uma câmara de mistura (7) do reator (1), o tubo de suprimento de gás (3) sendo pelo menos parcialmente circundado por um leito fluidizado anular estacionário (35), o qual é fluidizado pelo suprimento de gás de fluidização. As velocidades de gás do primeiro gás ou da mistura de gás, bem como do gás de fluidização para o leito fluidizado anular (35) são ajustadas de modo que os números de Froude de partícula no tubo de suprimento de gás (3) estejam entre 1 e 100, no leito fluidizado anular (35) entre 0,02 e 2 e na câmara de mistura (7) entre 0,3 e 30.
