The Kinetics Of Zinc Silicate Leaching In Sodium Hydroxide

1.5 h with 5 molL NaOH. The alkaline leaching of a low grade smithsonite ore was also carried out in columns after pelletizing the ore with cement. The best results showed over 80 zinc dissolution for a 20 days leaching period Feng et al., 2007. The leaching kinetics of zinc ores and concentrates has been

Mechanochemical Treatment To Remove Arsenic From Copper Ore

This study tested the removal of arsenic from copper ore concentrate via a mechanochemical treatment by planetary ball milling. The harmful components of ore, such as arsenic, are increasing year by year and decreasing the copper grade, therefore there is a strong need to improve the separation of arsenic from copper ore. The effect of grinding as a result of chemical activation caused by ...
