Abstract

"PROCESSO PARA AGLUTINAR CONCENTRADOS DO COBRE EM UMA PILHA DE CASCALHO, PARA SEREM LIXIVIADOS POSTERIORMENTE EM UM LEITO NãO-INUNDADO, AOS QUAIS UMA SOLUçãO AGLUTINANTE CONTENDO CLORETO DE CáLCIO, E UMA SEGUNDA SOLUçãO CONTENDO ìON DE SULFATO, SãO ADICIONADAS". Trata-se de um processo para aglutinar concentrados de minério, que podem ser de cobre, em uma pilha de cascalho, para serem lixiviados em um leito não-inundado, o qual compreende: a aderência artificial do concentrado à superfície de uma base de material sólido, o qual pode ser um material artificial, ou uma substância pétrea; o material aglutinado é empilhado, formando uma pilha de lixiviação; e é irrigado com uma solução de lixiviação que contem íons de pelo menos C1, Cu, e Fe.
