O termo diatomite \u00e9 aplicado tanto geol\u00f3gica como comercialmente \u00e0 acumula\u00e7\u00e3o sedimentar quase pura de fr\u00fastulas de diatom\u00e1ceas - os esqueletos microsc\u00f3picos de algas aqu\u00e1ticas unicelulares pertencentes \u00e0 classe das algas castanho-douradas, Bacillariophyceae. Os sedimentos s\u00e3o de gr\u00e3o fino, altamente siliciosos e consistem principalmente em s\u00edlica opalina amorfa com apenas pequenas quantidades de res\u00edduos org\u00e2nicos, minerais secund\u00e1rios e detritos cl\u00e1sticos n\u00e3o diatom\u00e1ceos ou cristalinos co-depositados. Os sin\u00f3nimos atualmente utilizados incluem terra de diatom\u00e1ceas e kieselghur. A terminologia mais antiquada e obsoleta inclui p\u00f3 de tr\u00edpoli, tripolite e terra infus\u00f3ria.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Na maior parte do mundo, o custo mais baixo e a recupera\u00e7\u00e3o mais elevada da extra\u00e7\u00e3o a c\u00e9u aberto, em compara\u00e7\u00e3o com a extra\u00e7\u00e3o subterr\u00e2nea, incentivam os operadores a utilizar m\u00e9todos de extra\u00e7\u00e3o a c\u00e9u aberto. Onde a sequ\u00eancia de diatomite \u00e9 espessa, s\u00e3o desenvolvidas bancadas de 1,5 a 15 m de altura. A constru\u00e7\u00e3o de bancadas n\u00e3o s\u00f3 facilita a remo\u00e7\u00e3o de min\u00e9rio e de res\u00edduos, como tamb\u00e9m permite o acesso imediato a muitas mais camadas e proporciona a oportunidade de misturar camadas com caracter\u00edsticas diferentes. Excep\u00e7\u00f5es not\u00e1veis s\u00e3o as minas subterr\u00e2neas na Europa, Am\u00e9rica do Sul e \u00c1sia, e a opera\u00e7\u00e3o de dragagem no Lago Myvatn, na Isl\u00e2ndia.<\/p>\n

Antes da extra\u00e7\u00e3o, os estratos de min\u00e9rio s\u00e3o cuidadosamente identificados nas faces da pedreira atrav\u00e9s de programas de amostragem e avalia\u00e7\u00e3o que determinam e confirmam a adequa\u00e7\u00e3o de cada estrato individual. Os estratos de min\u00e9rio podem ent\u00e3o ser classificados por qualidade e cuidadosamente segregados das unidades de res\u00edduos de qualidade inferior usando equipamento mecanizado. Uma vez que a diatomite \u00e9 um sedimento macio e f\u00e1cil de partir, os min\u00e9rios s\u00e3o normalmente arrancados com uma escavadora ou partidos da superf\u00edcie com uma p\u00e1 el\u00e9ctrica. A detona\u00e7\u00e3o dos min\u00e9rios n\u00e3o \u00e9 necess\u00e1ria nem poss\u00edvel devido \u00e0 suavidade inerente \u00e0 diatomite de qualidade comercial, \u00e0 sua porosidade e \u00e0 sua natureza absorvente. O material quebrado \u00e9 carregado por um carregador frontal ou um carregador de correia em cami\u00f5es de transporte para ser transportado para a \u00e1rea de armazenamento de crude ou para as pilhas de res\u00edduos.<\/p>\n

Normalmente, o teor de humidade do min\u00e9rio n\u00e3o processado varia entre 30% e 60%. Quando o clima \u00e9 favor\u00e1vel \u00e0 secagem solar, podem ser obtidas poupan\u00e7as de custos significativas atrav\u00e9s da redu\u00e7\u00e3o da humidade antes da moagem. Os graus brutos podem ser misturados ou utilizados separadamente, dependendo da aplica\u00e7\u00e3o final.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Devido \u00e0 sua porosidade, a diatomite tem sido amplamente utilizada como filtro para uma variedade de fins. \u00c9 utilizada para filtrar as impurezas de tudo, desde a cerveja e o vinho at\u00e9 aos \u00f3leos e gorduras. Do mesmo modo, a diatomite \u00e9 utilizada para filtrar as impurezas da \u00e1gua para produzir \u00e1gua pot\u00e1vel (pot\u00e1vel) em sistemas p\u00fablicos de \u00e1gua. Nesta situa\u00e7\u00e3o, a diatomite remove as bact\u00e9rias e os protozo\u00e1rios.<\/p>\n

A utiliza\u00e7\u00e3o mais antiga da diatomite \u00e9 como um abrasivo muito suave e, para este efeito, tem sido utilizada em pastas de dentes e polimentos de metais.<\/p>\n

Tamb\u00e9m \u00e9 utilizado em papel, tintas, tijolos, azulejos, cer\u00e2micas, pl\u00e1sticos, sab\u00f5es, detergentes e outros produtos como carga. Um agente de enchimento \u00e9 uma subst\u00e2ncia que aumenta o volume de um produto e\/ou preenche o espa\u00e7o.<\/p>\n

A diatomite tamb\u00e9m encontrou valor como material isolante em mecanismos de alta temperatura, como fornos e caldeiras. Tamb\u00e9m provou ser eficaz como isolante ac\u00fastico.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
