Dealing With Scat in Mill Processing - PumpEng

In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed.

Tailings - Wikipedia

15-02-2004  Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining,

22-04-2020  Ore is hauled to an in-pit crusher and waste is hauled to nearby waste storage stockpiles. A new flotation mill is under construction at Endako which is expected to increase the ore processing capacity to 50,000 tpd. As a consequence, the mine ore and waste production rates are being increased in order to sustain ore production to the mill.

Reduce ore dilution and loss in open pit mines BMT

Dilution occurs when waste is unintentionally with material containing ore and sent to the mill. When a cost is given for Dilution, it is the cost of processing the waste material through the mill. Misclassification occurs when material containing grade (ore) is sent to an incorrect downstream location (i.e. a stockpile); for example, sending high grade material to a low grade stockpile.
