Coffee is known as one of the most popular beverages around world. belongs to botanical family Rubiaceae and genus coffea. The two economically important species are C. arabica (arabica coffee) canephora (robusta coffee).The health benefits coffee due presence many biologically active components such caffeine, chlorogenic acid, nicotinic quinolinic trigonelline, tannic pyrogolic acid. postharve...

Roasting is the most common way for pistachio nuts processing, and the purpose of that was to increase the products total acceptability. Purpose of this study was to investigate the effect of temperature (90, 120 and 150°C), time (20, 35 and 50 min), and roasting air velocity (0.5, 1.5 and 2.5 m/s) on geometrical attributes of pistachio nuts and kernels including principle dimensions, shape fac...

The separation of graphites and cathode materials from spent lithium-ion batteries (LIBs) is essential to close the loop material used in LIBs. In this study, roasting characteristics LIB are carefully analyzed, effects on surface morphology elemental chemical states electrode fully investigated by thermogravimetric analysis, SEM-EDS, XPS explore roasting–flotation enhancement mechanism. Then, ...

In this study, the production technology of rare-earth oxides from Eskişehir-Beylikova complex ore that contains barite, fluorite, elements, and thorium were investigated. processes can be used in thorium-free mixed rare earth tested. Roasting, leaching, solvent extraction precipitation methods respectively. Roasting temperature roasting duration determined as 600 °C 1 hour, The optimum leachin...

In this work, thealkaline roasting and sulfuric acid leaching processes were employed to extract vanadium from the magnetite ore of Saghand mine in central Iran. The response surface methodology based on the central composite design model was applied to optimize the parameters involved in the processes. The studied roasting parameters were temperature (900-1100 °C), sodium carbonate percentage ...
