The hydraulic behaviour of the entire karst aquifer is strongly influenced by the presence of solutionally enlarged fractures and conduits. Numerical models of karst aquifers thus need to include specific high-conductivity elements that represent the conduits and lower-conductivity elements that represent the less karstified rock volumes.

5 days agoMagnesium oxide (MgO) is critical for improving the metallurgical properties of magnesium pellets. However, it can reduce the cold compressive strength (CCS) of such pellets; in contrast, moderate SiO 2 contents can improve the CCS. In this work, the effect of serpentine mineral on the consolidation behaviors of a magnesium acid pellet under high-silicon iron ore concentrate were investigated.

For all the fired iron ore pellets, the degree of reduction in coal was more intense in the first 30 minutes after which it became small. Slow heating led to higher degree of reduction in fired pellets than rapid heating. All the iron ores exhibited more than 90% reduction in their fired pellets in 2 hrs. time interval at a temperature of 9000C.
