2020-4-8 · 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.
