Abstract

La présente invention a trait à une technique qui facilite une analyse de constituants dans des opérations de lixiviation par l'utilisation d'énergie lumineuse et d'une transmission par fibre optique de lumière durant les opérations de lixiviation. La lumière est utilisée in situ en combinaison avec une cellule d'écoulement afin de mesurer des constituants souhaités, par exemple, du cuivre, dans un flux d'écoulement de fluide. En outre, les données obtenues via la cellule d'écoulement peuvent être fournies à un système de traitement de données qui peut être utilisé pour fournir automatiquement des informations, par exemple, la concentration des constituants, dans le flux d'écoulement. Dans de nombreuses applications, le système de transmission à fibre optique in situ et la cellule d'écoulement peuvent être utilisés en combinaison avec le système de traitement de données afin de fournir des informations en temps réel sur le flux d'écoulement.
