substitute valence
1.The refinements of beryl structure suggest that divalent canons substitute for Al in octahedral slies and Li for Be in tetrahedral ones, while alkali canons are accommodated by the channel of beryl to balance the deficiency of positive charges resulting from the replacement of octahedral Al and tetrahedral Be by canons of lower valence. Normally.
2.In order to further raise the high-valence iron concentrate quality, reduce the foreign inclusion, increase enterprises economic efficency, the MVS 2020 electromagnetic vibrating wire screen is adopted to substitute for the section of cyclones, in solving the problem of the counter-negtive collection of the cyclone grading, realizing the selective rubbing and enhancing the final rubbing product granularity. The test results indicate that the rubbing fineness is increased compared with that from the original process, and the reground iron ore concentrate quality is obviously improved.
