Article Synopsis
- Gallium metal is found in Fankou lead-zinc ore, and its extraction using the zinc hydrometallurgy process faces challenges due to impurities affecting electrowinning efficiency.
- The study reveals that aluminum impurities do not affect gallium product quality but lower current efficiency, whereas zinc impurities have a significant negative impact, leading to reduced gallium purity.
- Optimal conditions for gallium electrowinning, including specific alkali concentrations, are recommended to enhance production efficiency in zinc hydrometallurgy systems.
The Grain for Green Program (GGP) was the most all-embracing program of ecological reconstruction implemented in China. To estimate carbon storages and carbon sequestration potentials of the GGP forests, the study presented in the paper collected data spanning from 1999 to 2010, such as tree species, tree planting area relevant to the GGP, empirical growth curves suitable for different planted tree species in China, as well as wood density (WD), biomass expansion factor (BEF), carbon fraction (CF) of different trees species, and estimated the carbon storages of the biomasses of GGP forests from 1999 to 2050. It showed that the total carbon storage of the biomass of GGP forests was 320.
