Extraction Rate of Hydrochloric Acid by Long-Chain Alkylamine in Horizontal Rectangular Channel

Extraction of Alumina from Local Clays by Hydrochloric Acid Process

A bench work study was carried out to investigate the use of kaolinitic clay containing 29.4% Al2O3 extremely abundant in Saudi Arabia for the production of pure alumina by calcination at 700 o C for 1h (recommended by previous investigators) then leached by hydrochloric acid. The effects of leaching temperature (25 o C to boiling temperature), period of activation (10-150 minutes), acid concen...

Extraction of Gold(iii) with Mbimtt from Hydrochloric Acid

On rate-controlling factors of long chain fatty acid oxidation.

Under appropriate conditions, mitochondria from red and white skeletal muscle of rabbit and from heart and liver of rat respired as rapidly with palmitoyl-coenzyme A plus carnitine as with palmitoyl carnitine. The ability of heart and skeletal muscle mitochondria to oxidize palmitoyl groups is limited by the acetyl-CoA-producing capacity of the 0 oxidation cycle rather than through a limitation...

Solvent Extraction of Gold from Hydrochloric Acid-Leached Nigerian Gold Ore by Tributylphosphate

This paper presents an experimental study on the dissolution kinetics and solvent extraction of total gold from Ijero-ekiti (Nigeria) gold ore deposit by hydrochloric acid leaching followed by extraction with Tributylphosphate (TBP) in kerosene. The leaching investigation showed that the gold ore dissolution in HCl solution increases with increasing acid concentration, temperature and with decr...

Extraction of gallium(III) from hydrochloric acid solutions by trioctylammonium-based mixed ionic liquids.

The extractabilities of aluminium(III), gallium(III), and indium(III) from hydrochloric acid solutions were investigated using a mixture of two protic ionic liquids, trioctylammonium bis(trifluoromethanesulfonyl)amide ([TOAH][NTf(2)]) and trioctylammonium nitrate ([TOAH][NO(3)]). At a HCl concentration of 4 mol L(-1) or more, gallium(III) was nearly quantitatively extracted and the extractabil...
