Gravity Separation Technology for Oil Sands. This year, the synthetic crude producers in Alberta predict that they will average 721,000 barrels per day, which amounts to mining 1.4 million tons per day of oil sands. This figure is expected to double in the next 10 to 15 years. Moving that amount of material requires skill, technology and patience.

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.
