The laboratory parallel experiment have been completed for two kinds of schemes with "v-ti concentrates + general concentrates" and "all V-Ti concentrates" for different ore matching structure and rising pellet alkalinity to 0.

The performance of every iron ore fine agglomeration, rational scheme and technical parameters of ore matching for sintering were studied in this paper.

The performance of every iron ore fine agglomeration, rational scheme and technicalparameters of ore matching for sintering were studied in this paper.

As for the thermoreduction of magnesium, it not only requires strictly to its ore chemicalcomposition and mineral structure, but also controls strictly to its technique conditions such asvacuum, burden, reducing temperature and period of heat preservation etc.

The relationships between montmorillonite mineral structure and physical-chemical properities are also discussed.

Through researching the regional and geological background and the ore structure of Lagaluo iron deposit, this paper describes the geological characteristics of Lagaluo iron deposit, and expounds the origin of deposit.

We find out the chemistry compositions,mineral compositions,ore structure,dissemination characteristics and particle size distributions of the target minerals and the liberations of the grinding products,and the analysis concerning with the factors affecting the performance of the ore dressing is done.
