of the Interior, Bureau of Mines, A cycle bench-scale experiment of the simplified process showed that the FeCl3 concentration built up to g/L in the recycle stream. This did not interfere with any of the unit operations or final alumina product purity because Fe forms stable soluble chloride complexes when sparged with HC1 and is easily washed from the large aluminum Cited by: 1.

Aluminum chloride pregnant liquor was produced that analyzed pct Al2O3, and contained more than 97 pct of the alumina in the liquid phase of the slurry.

Bench-scale settling tests were used to correlate fines content of leach residue to thickener area and flocculant requirements." - NIOSHTIC-2Cited by: 3.
