MINING. Once the oil sands is hauled out of the mine, the ore is first processed in an Ore Preparation Plant (OPP), where clumps of oil sands are broken down and mixed with hot/warm water to produce a pumpable slurry. OPP facilities have evolved considerably in recent years and provide a critical first step in the extraction of bitumen.

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore.

Cleaning and separating sand into coarse, medium, and fine grades; Storage / Stockpiling.

Finer sand, called "40-70" sand, is sold for natural gas drilling. The second factor that affects the profit margin of a sand mine is how much unmarketable material, called overburden, is sitting on top of the sand. The cost of moving and storing this excess soil can add up quickly, so smaller amounts of overburden mean higher profits.
