Talco<\/strong> \u00e9 amplamente utilizado, e o min\u00e9rio de talco puro \u00e9 raro, geralmente acompanhado de outros minerais, tais como clorite, magnesite, tremolite, dolomite, siderite, quartzo, pirite, etc. Estes minerais alteram a composi\u00e7\u00e3o qu\u00edmica do min\u00e9rio e afectam significativamente as propriedades f\u00edsicas do talco. A fim de melhorar a qualidade e satisfazer as necessidades da produ\u00e7\u00e3o industrial, o talco tem de ser transformado.
\n\"talco\"<\/p>\n

Talco propriedade<\/h2>\n

Talco<\/a> recebe o seu nome devido \u00e0 sua suavidade e forte cremosidade. O talco tem um elevado grau de isolamento el\u00e9trico, isolamento t\u00e9rmico, elevado ponto de fus\u00e3o e forte capacidade de adsor\u00e7\u00e3o de \u00f3leo, pelo que tem uma vasta gama de aplica\u00e7\u00f5es na ind\u00fastria. Entre elas, o talco consumido pela ind\u00fastria do papel representa cerca de 60% do total. Al\u00e9m disso, o talco \u00e9 tamb\u00e9m amplamente utilizado em muitos dom\u00ednios, como a medicina, a ind\u00fastria qu\u00edmica, os t\u00eaxteis, a cer\u00e2mica e a escultura. A ind\u00fastria do papel exige um baixo teor de ferro no talco. Por conseguinte, o ferro, o mangan\u00eas, n\u00edquel<\/a>e o tit\u00e2nio contidos no min\u00e9rio bruto t\u00eam de ser separados para obter talco de alta qualidade.<\/p>\n

1. Flota\u00e7\u00e3o<\/h2>\n

Devido \u00e0 capacidade natural de flutua\u00e7\u00e3o do talco, este pode ser flutuado com um coletor de \u00f3leo de hidrocarbonetos. O coletor normalmente utilizado \u00e9 o querosene, agente espumante do \u00f3leo de flutua\u00e7\u00e3o. O processo de flota\u00e7\u00e3o do talco \u00e9 relativamente simples, exigindo apenas uma sele\u00e7\u00e3o bruta e uma sele\u00e7\u00e3o de varrimento, e 3-4 selec\u00e7\u00f5es. No entanto, o concentrado de talco tem um tamanho de part\u00edcula fino e \u00e9 dif\u00edcil de desidratar. m\u00e1quina de flota\u00e7\u00e3o<\/a><\/p>\n

2. Sele\u00e7\u00e3o manual<\/h2>\n

A triagem manual \u00e9 selecionada manualmente de acordo com a diferen\u00e7a de suavidade do talco e dos minerais de ganga. O talco tem uma boa suavidade, quanto maior o grau, melhor a suavidade, e \u00e9 f\u00e1cil de identificar manualmente. A maioria das minas de talco nacionais produz frequentemente blocos de talco de alta qualidade por sele\u00e7\u00e3o manual. Nos \u00faltimos anos, os pa\u00edses estrangeiros investigaram com sucesso uma m\u00e1quina de sele\u00e7\u00e3o chamada rappeller, que pode separar o talco da ganga de acordo com os diferentes coeficientes de fric\u00e7\u00e3o do min\u00e9rio, de modo a realizar a mecaniza\u00e7\u00e3o da sele\u00e7\u00e3o manual do talco.<\/p>\n

3. Beneficia\u00e7\u00e3o eletrost\u00e1tica<\/h2>\n

Para al\u00e9m do talco, o talco tamb\u00e9m cont\u00e9m minerais como magnesite, magnetite, pirite, tremolite, etc. O tamanho das part\u00edculas incorporadas \u00e9 de cerca de 0,5 mm. Num campo eletrost\u00e1tico, o talco tem carga negativa e a magnesite tem carga positiva, e tanto a magnetite como a pirite s\u00e3o bons condutores, pelo que \u00e9 f\u00e1cil separar os minerais acima referidos num campo el\u00e9trico. separador el\u00e9trico<\/a><\/p>\n

4. Separa\u00e7\u00e3o magn\u00e9tica<\/h2>\n

Para al\u00e9m da finura e pureza exigidas para o concentrado de talco, este deve tamb\u00e9m possuir o Baidu n.\u00ba 1. Devido \u00e0 exist\u00eancia de minerais de ferro tingidos no min\u00e9rio, a flota\u00e7\u00e3o por si s\u00f3 n\u00e3o \u00e9 suficiente. Por vezes, \u00e9 necess\u00e1rio utilizar a separa\u00e7\u00e3o magn\u00e9tica para remover os materiais que cont\u00eam ferro. A Uni\u00e3o Sovi\u00e9tica e o Canad\u00e1 t\u00eam exemplos de separa\u00e7\u00e3o magn\u00e9tica para remo\u00e7\u00e3o de ferro. A utiliza\u00e7\u00e3o da separa\u00e7\u00e3o magn\u00e9tica h\u00famida pode reduzir o teor de ferro do concentrado de talco de 4-5% para 0,7. separador magn\u00e9tico <\/a><\/p>","protected":false},"excerpt":{"rendered":"
