Abstract

"PROCESSO PARA EXTRAIR MINéRIO DE UM VEIO QUE TEM PAREDES LATERAIS OPOSTAS, E, MéTODO PARA EXTRAIR MINéRIO DE UM DEPóSITO DE VEIO MINERALIZADO". é descrito um método sem explosão para extrair minério de um depósito de veio mineralizado (12) em que o veio é extraído fazendo com que o minério compreendido entre as paredes da rocha (16) que delimitam o veio (12) se quebrarem em fragmentos. Os fragmentos de minério são recuperados por aspiração e subseq³entemente processados para recuperar o mineral precioso."A process for extracting ore from a vein which has opposite side walls, and a method for extracting ore from a mineralised vein deposit". A blast-free method for extracting ore from a mineralized shaft deposit (12) wherein the shaft is extracted causing the ore comprised between the rock walls (16) that delimit the shaft (12) to break into fragments is described. The ore fragments are recovered by aspiration and subsequently processed to recover the precious mineral.
