Directions: Sequence the following processes of mining based on the diagram. Numbe r them from 1-9. La. The loaded carbon is fed into an elution column where the bullion is washed off. _b. Ore from both open pit and underground is stockpiled separately at the mill before being fed into a mill with lime, water and steel balls. _c. The loaded cathodes are rinsed to yield a gold and silver bearing sludge which is dried, mixed with fluxes and put into the furnace. _d. A rubber belted conveyor transports the ore and waste rock from the open pit, approximately two kilometers, via a tunnel through a hill, to the mill and waste rock embankments. Le. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground. See more detail on mining _f. Excess water is pumped to the water treatment plant and treated to the required standards before discharge into the river. g. Water is decanted off and used in the process plant or treated before it is discharged. h. The primary crushers break the larger rocks down to a size suitable for transport on the conveyor belt _i. A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved.
