O tanque de lixivia\u00e7\u00e3o agitado<\/strong> is essential equipment in processamento de min\u00e9rio<\/strong><\/a>, designed to facilitate the dissolution of valuable minerals by uniformly mixing ores with solvents. This equipment typically consists of a large tank with an integrated stirring mechanism, which can be mec\u00e2nico<\/strong>(mechanical stirring leaching tank), pneumatic<\/strong>(air stirring leaching tank), or a combination of both<\/strong>(air & mechanical combined stirring leaching tank).<\/strong> The design and operation of stirred leaching tanks vary based on metallurgical requirements, ensuring optimal extraction efficiency.<\/p>\n

Let’s explore the different types of stirred leaching tanks and their unique features.<\/p>\n

 <\/p>\n

1. Mechanical Stirring Leaching Tank<\/h2>\n

In the mechanical stirring leaching tank, the high-speed rotating mechanical stirring paddle stirs the slurry. The propeller-stirring leaching tank is a commonly used mechanical-stirring leaching tank in production. When the propeller rotates rapidly, the slurry in the tank flows into the central slurry receiving pipe through each branch pipe, thus forming a vortex, and the air is sucked into the vortex so that the oxygen content in the slurry reaches the saturation value. At the same time, the rotation of the propeller pushes the slurry entering the receiving pipe to the bottom of the tank. Then it returns from the bottom of the tank to rise along the tank wall and enter the central slurry receiving pipe through the circulation pipe to realize multiple circulations of the slurry.<\/p>\n

Na pr\u00e1tica de produ\u00e7\u00e3o, por vezes, s\u00e3o inseridos v\u00e1rios tubos verticais de ar comprimido no tanque, ou s\u00e3o instalados elevadores de ar na parede interior (exterior) do corpo do tanque para aumentar o teor de oxig\u00e9nio e a intensidade de agita\u00e7\u00e3o no chorume.<\/p>\n

2. Axial Flow Pump Agitator Leaching Tank<\/h2>\n

O bomba de fluxo axial tanque agitador de lixivia\u00e7\u00e3o<\/strong> utiliza a rota\u00e7\u00e3o r\u00e1pida do impulsor para aspirar a lama do fundo do tanque para o tubo central e atir\u00e1-la para cima, para o refletor c\u00f3nico. Uma vez que a superf\u00edcie inferior do refletor rotativo \u00e9 c\u00f3nica, a lama muda de dire\u00e7\u00e3o em 90 graus depois de ser lan\u00e7ada para a superf\u00edcie c\u00f3nica do refletor e retira-se para a superf\u00edcie da lama no tanque em forma de leque. Neste momento, a \u00e1rea de superf\u00edcie da lama em contacto com o ar \u00e9 grande, e a lama \u00e9 preenchida com ar. Para evitar que a lama se desvie no centro da superf\u00edcie da lama devido \u00e0 grande quantidade de s\u00f3lidos, o que n\u00e3o \u00e9 prop\u00edcio para o efeito de suc\u00e7\u00e3o do impulsor, uma placa de deflex\u00e3o \u00e9 instalada na superf\u00edcie interna do tubo de suc\u00e7\u00e3o. Devido \u00e0 rota\u00e7\u00e3o cont\u00ednua da p\u00e1 de agita\u00e7\u00e3o, a lama \u00e9 continuamente descarregada da porta de suc\u00e7\u00e3o do tubo central para realizar a circula\u00e7\u00e3o da lama, de modo que a lama \u00e9 distribu\u00edda uniformemente em todo o tanque de lixivia\u00e7\u00e3o e \u00e9 frequentemente saturada com oxig\u00e9nio, realizando assim a lixivia\u00e7\u00e3o de cianeto de ouro.<\/p>\n

 <\/p>\n

3. Air Stirring Leaching Tank (Tower)<\/h2>\n

O tanque de lixivia\u00e7\u00e3o com agita\u00e7\u00e3o de ar<\/strong> utiliza a a\u00e7\u00e3o pneum\u00e1tica do ar comprimido para conseguir uma agita\u00e7\u00e3o uniforme e forte do chorume no tanque. A parte superior do tanque de lixivia\u00e7\u00e3o \u00e9 uma coluna alta, e o fundo \u00e9 um cone, que \u00e9 composto principalmente de um corpo, um tubo intermedi\u00e1rio, um tubo de ar comprimido, um tubo de alimenta\u00e7\u00e3o e um tubo de descarga. Durante o funcionamento, o chorume entra no tanque atrav\u00e9s do tubo de alimenta\u00e7\u00e3o e o tubo de ar comprimido vai diretamente para a parte inferior do tubo central. O ar comprimido sobe no tubo central em estado de bolha, fazendo com que a densidade da lama no tubo central seja menor do que a densidade da lama no espa\u00e7o anular fora do tubo central. Como resultado, a lama no tubo central continua a subir, e a lama no espa\u00e7o anular fora do tubo central continua a descer, realizando a circula\u00e7\u00e3o da lama. A intensidade da agita\u00e7\u00e3o da lama pode ser ajustada atrav\u00e9s da regula\u00e7\u00e3o da press\u00e3o e do caudal do ar comprimido. A agita\u00e7\u00e3o da lama do tanque de lixivia\u00e7\u00e3o agitado por ar comprimido \u00e9 muito forte, o que pode fazer com que o teor de oxig\u00e9nio na lama se aproxime do valor de satura\u00e7\u00e3o.<\/p>\n

O tanque de lixivia\u00e7\u00e3o com agita\u00e7\u00e3o de ar pode ser funcionamento intermitente ou cont\u00ednuo.<\/strong> No primeiro caso, o chorume \u00e9 descarregado atrav\u00e9s do tubo de descarga inferior no final da lixivia\u00e7\u00e3o e, no segundo, o chorume \u00e9 descarregado atrav\u00e9s do tubo de descarga superior e entra no caix\u00e3o de lixivia\u00e7\u00e3o seguinte.<\/p>\n

 <\/p>\n

4. Air & Mechanical Combined Stirring Leaching Tank<\/h2>\n

O tanque de lixivia\u00e7\u00e3o com agita\u00e7\u00e3o mec\u00e2nica e de ar combinada \u00e9 equipado com<\/strong> um elevador de ar e um ancinho mec\u00e2nico no centro, ou um elevador de ar \u00e9 instalado em torno do tanque, e um tubo de circula\u00e7\u00e3o de lama e uma p\u00e1 de agita\u00e7\u00e3o em espiral s\u00e3o instalados no centro do tanque. Por isso, tamb\u00e9m \u00e9 chamado de tanque misturador de lixivia\u00e7\u00e3o do tipo ancinho. O tanque caracter\u00edsticas<\/strong> deste tipo de tanque de lixivia\u00e7\u00e3o por agita\u00e7\u00e3o s\u00e3o um corpo curto do tanque, nenhum sedimento no fundo do tanque, alta velocidade de lixivia\u00e7\u00e3o de ouro e baixo consumo de ftalatos. O princ\u00edpio de funcionamento<\/strong> is that the slurry enters the tank through the feed port located at the top of the tank, and settles to the bottom of the tank in layers in the tank. The slurry settled at the bottom of the tank gathers at the hollow lifting pipe mouth with the help of the rotation of the rake (I -4r\/min). Under the action of compressed air, the concentrated slurry rises along the air-lifting pipe and flows into the two flow troughs with holes at its upper part, flows back to the tank through the flow holes, and the flow core rotates with the vertical axis, and the slurry is evenly distributed at the tip. The leached slurry is continuously discharged from the discharge port opposite to the feed port, thereby realizing continuous operation.<\/p>\n

O ar \u00e9 difundido no chorume atrav\u00e9s da conduta de ar, da v\u00e1lvula de convers\u00e3o de ar e do eixo oco, de modo a que o chorume seja suspenso e mantenha um elevado teor de oxig\u00e9nio dissolvido, assegurando assim as necessidades das condi\u00e7\u00f5es do processo de lixivia\u00e7\u00e3o por aera\u00e7\u00e3o. Este tanque de lixivia\u00e7\u00e3o tem as seguintes caracter\u00edsticas vantagens<\/strong> de baixo consumo de energia, alta efici\u00eancia, agita\u00e7\u00e3o uniforme e opera\u00e7\u00e3o fi\u00e1vel. \u00c9 particularmente adequado para<\/strong> lixivia\u00e7\u00e3o por agita\u00e7\u00e3o em instala\u00e7\u00f5es de aera\u00e7\u00e3o de lama completa. Atualmente, tornou-se o principal equipamento de lixivia\u00e7\u00e3o das f\u00e1bricas nacionais de pasta de carbono.<\/p>\n
