STUDY OF SPECIFIC SURFACE ENERGY OF ORES AT DISINTEGRATION WITH THE USE OF CHEMICAL REAGENTS
Abstract
The article describes studies of the process of mineral raw refinement in dry, wet form and with addition of chemical reagents. Specific energy spent to refinement has been determined in the course of disintegration, as well as specific surface of particles before and after refinement has been measured. The values of refinement of inter-phase surface area of disintegrated mineral particles and values of specific surface energy have been calculated. With the help of performed studies one may obtain quantitative expression of grindability with the use of different modes of disintegration and chemical reagents. Knowing specific surface energy used to refine mineral raw material will enable making reasonable corrections of technological processes to improve their performance. The parameter of specific surface energy of ores can serve as adjustable parameters for controlling the kinetics of the grinding process. The value of specific surface energy of ores essentially depends on the material composition of ore, the genetic features of the formation of the ore body, and the location of selection of the technological sample.
