dc.description.abstractThe possibilities for sintering a fine scheelite concentrate containing a significant amount of tungsten in the form of calcium tungstate (CaWO4) were considered. Scheelite originates from the Grncharitsa deposit, located near the town of Velingrad, Bulgaria The scheelite fine fraction was obtained after numerous technological and transport operations of the coarse fraction, as well as after flotation treatment of scheelite raw material. Experimentation is at the laboratory level. The influence of flux on the agglomeration process was established. Studies without flux have been also done. High-temperature metallurgical equipment was used, through which it is possible to follow the results of the process of thermal coagulation (sintering) of the charge materials. The used methodology of conducting the experiments is close to that of the classic agglomeration process in terms of thermal partial melting of the particles of the charge, by burning soot carbon, but without permeation of air through the layer of the charge (laboratory crucibles have a relatively small working volume and it was assumed that air in and above the charge will be sufficient). The main goal is to obtain a qualitative sinter and to draw conclusions regarding the processing of the scheelite fine fraction in a larger-scale apparatus, for example agglomeration.
