The Difference

The magnetic performance of steel slag is special because it has a high content of Fe2O3. In this study, the difference of chemical compositions, mineral compositions, and particle size distributions between the two parts of steel slag by magnetic separation was investigated. The results show that the difference of chemical compositions especially the main oxide contents between the two parts of steel slag by magnetic separation is very small. And the difference of mineral compositions between the two parts of steel slag by magnetic separation is also very small. However, the particle size distributions of the two parts of steel slag by magnetic separation may differ from each other when steel slag contains many coarse particles.

AbstractOptimum conditions for synthesizing monoclinic and triclinic Mg2B2O5 compounds by high-temperature solid-state reactions were investigated. Mixtures composed of boric acid and magnesium oxide at MgO:B2O3 mole ratios of 1:0.25, 1:0.5 and 1:1.5 were heated for 1 hour at temperatures between 600–1050°C and the formed phases were identified by XRD analysis. Monoclinic Mg2B2O5 was formed by heating at 850°C for 4 hours together with minimum amounts of triclinic Mg2B2O5, while triclinic Mg2B2O5 was formed as a single phase at 1050°C for the same reaction time. The products obtained at optimum conditions were subjected to a series of tests to determine their chemical compositions, particle size distributions, surface area values, IR spectra and TG/DTA patterns.

Important Basis

Mineralogy research of the copper and nickel ore from Jinchuan is completed in detail that shows the mineral compositions and their percentage and particle size distributions of the valuable minerals. The main valuable minerals are pyrite, violarite, chalcopyrite which are closely associated with other sulphide minerals. These results provide an important basis for the beneficiation tests.
