1 ball milling assisted by naoh method: the appropriate amounts of cono 3 29h 2 o and naoh in a 1:2:8 molar ratio respectively were mixed by ball millingMilling was performed in a planetary ball mill fritsch pulverissette the milling time was 4 hours at speed of 300 rpm with a ball-to-powder mass ratio of 10:1.
Abstract: a process consisting of ball milling followed by naoh leaching was developed to selectively dissolve alumina from black drossFrom the ball milling treatment it was found that milling speed greatly affected the leaching behavior of silica and the oxides of ca fe mg and ti present in dross.
After 4 h of ball milling the wood powder was completely dissolved in 6 wt naoh aqueous solution under vigorous magnetic stirring for 10 to 20 min at room temperature.
