Stability and phosphorus leaching of tilapia feed in water
(Univ Federal Santa Maria, 2019-01-01)
The present research aimed to investigate the stability of pellets and phosphorus leaching of diets formulated for juveniles of Nile tilapia (Oreochromis niloticus), with different sources of phosphorus and different ...
Leaching optimization of mining wastes with lizardite and brucite contents for use in indirect mineral carbonation through the pH swing method
(2017-01-10)
This study investigated the leaching process in order to maximize Mg and Fe extraction and to produce amorphous silica (SiO2) with high purity. For this, a mining waste identified as S-GO was employed; which is a serpentinite ...
