    摘要: Mined material is transported within and outside a mine (10) in containers (26) that are fixed. discrete load units. namely containers that define a fixed maximum volume that can be carried in each container. The containers can be carried on or coupled to and then removed from vehicles (16) or other transport options. such as flatbed trucks. flatbed rail carriages or overhead suspension units. The containers can be stored at designated container storage facilities (28) in the mine. The container storage facilities are holding areas for loaded containers at mines until decisions are made to transport the containers to mineral processing plants (30) in the mine or to end-use customers. for example via rail to a shipping port (24).

    摘要: A method of leaching copper-containing ores includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor in the presence of an additive that enhances the dissolution of copper from copper minerals in the ores and concentrates by forming a complex between (a) sulfur, that has originated from copper minerals in the ores, and (b) the additive. A method of leaching copper-containing ores includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor in the presence of a nitrogen-containing organic complexing additive that forms a complex between sulfur, that has originated from copper minerals in the ores, and the additive.
