Understanding the impact of geotechnical ore properties and blast
The mine is classified as a disseminated sediment-hosted gold deposit, which is mined, milled and later processed by CIC/CIL (carbon in column/carbon in leach). The comminution circuit consists of jaw crusher, SAG and Ball mill circuit as presented in Fig. 1. The targeted grind size was P 80 of 150 µm. The blasting, crushing and grinding ...
Insights From Simulation of a CIL/CIP Circuit
A model was developed of a CIL/CIP circuit for recovery of gold and silver. The model uses a simple two rate representation of the leaching kinetics. Parameters for the leaching kinetics may be simply obtained by sampling the feed to a circuit and the tailings from each tank and
