Portuguese term or phrase: circuitos de beneficiamento
Processos de beneficiamento: No beneficiamento, a alimentação da britagem primária com material mais homogêneo, proveniente de lavra com técnicas adequadas de desmonte, propicia uma maior eficiência do processo, além de uma possível redução na geração de finos e de material particulado. Ainda com relação aos ***circuitos de beneficiamento***, cabe destacar os seguintes aspectos condicionadores do ordenamento territorial e da sustentabilidade:

- O processamento de rochas com tendência lamelar pode exigir estágios adicionais de britagem, com maiores custos e impactos ambientais. Conseqüentemente, a adequada seleção e o conhecimento técnico-científico do depósito representam fatores relevantes na promoção das condições de produtividade e de competitividade privada e social do empreendimento.

- Se, por um lado, o despoeiramento por umidificação permite solucionar o problema do lançamento de material particulado, por outro, como decorrência, o material pulverulento agregado à brita tem excedido o limite de 1% definido pela ABNT (NBR 7211).

- Exigências ambientais crescentes, referentes à emissão de particulados, bem como rigorosas especificações de qualidade deverão exigir mudanças nas unidades de beneficiamento, evidenciando uma tendência à adoção dos circuitos de processamento encapsulados.
