Increasing the effectiveness of utilization of magnesite raw materials

Conclusions

The work conducted at the ‘Magnezit’ Combine on processing the reserves of low-quality magnesite masses on an industrial scale shows the technological acceptability of such treatments. It permits one to utilize the mineral reserves to a greater extent, improve the supply of raw materials to the engineering plants without considerably increasig the industrial base (investment) of the plants belonging to the Mining Administration, and thereby improve their main technoeconomical indices.

The experience gained on the clearing (working) operations at the special dumps of the magnesite masses showed that at the present level of development, the problems of this type require scientific recommendations on the geological description of the formation of the dump bodies under consideration and, based on this, to search for the optimum direction of development and the regime of mining operations with regard to sorting and also to develop the principles of improving the effectiveness of processing the fine fractions of the low-quality magnesite masses.

Working out such recommendations permits one to improve not only the effectiveness of processing low-quality mineralogical masses but the entire mineral-handling (mining) industry, thereby placing this problem among the most important current problems.
