Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to this mixture of sand, clay, bitumen, and water in a ...
How phosphate is mined and processes Mining Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines (or picks and shovels).
