2011 China mainland famous mining auxiliary PAM
A .Ore washing and flotation,it is used for separating the minerals and gangue. Many minerals such as Fe, Coal, phosphate ,diamond , Zn , Uranium,sand and so on , they use this process .
In this time, the flocculants could be used for :
separate ore from the water ,so we could reuse the water .dewatering the sludge made by the decline of the ore.separating useful materials from the water when they float .B. In the process, sometime we need dissolve the metal materials into the acid and Alkali. We could use flocculant to separate the impurities from it .and the metals could be recovered as –OH, and –salt type. We could use nonionic pam or anionic pam . nonionic pam could be used in the acid and –salt solution .
