Abstract:With the continuous increase of copper production in Guiye Smelter, the consumption of various local concentrates and container imported concentrates is also increasing. Due to the limited unloading capacity, the imported container concentrates and local concentrates cannot be unloaded at the same time, resulting in container demurrage phenomenon and high demurrage costs. In order to meet the requirements of container imported and local concentrates unloading, a special unloading platform for imported concentrates is added in the No.2 warehouse area of the current material preparation system II, and a new canopy is built on the east side of warehouse 3# to meet the requirements of unloading operation in rainy days.
