Bitumen Extraction Explained Oil Sands Magazine

However, the effect is far more pronounced when processing low-quality ores. If the ore quality is good, then bitumen recovery is generally quite good regardless of process temperature. If the feed quality is poor (low grade, high fines) then a lower operating temperature greatly hinders bitumen recovery.

How Are Diamonds Mined And Extracted From the Ground

To make mining efficient and effective, the raw rock and soil are typically not examined on-site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.

Improving Bitumen Recovery from Poor Processing Oil Sands

Low bitumen recovery and poor froth quality are always encountered when processing poor oil sands using water-based extraction processes.
