Aluminium Bauxite (is water needed)
Is water needed in the extraction of aluminium from bauxite in either the Bayer or Hall-Heroult proccesses? Please reply as soon as you can :) hehe
i knew that was wrong, coz my answer should be in the 50's haha..thanks though, great help can i ask how you got sinA and sinB with that information :) no point in me just copying it i would like to know how you got it
well, i got: (-4/5)(12/13) - (4/5)(7/13) therefore (-48/65) - (28/65) therefore: answer = (-76/65)
yeah thats right, can u go on?
if cosA = 4/5; sin <0; cosB = 12/13; 0<B<90, determine sin(A-B) thanks ... :)
I desperatly need help, i need to know everything there is to know about the recovery of ALUMINIUM that is recovered from BAUXITE ORE, the process, the cost, everything. Please, if you have any knowledge or know of any GOOD webpages, please post them here. thanks:)
