Abstract:

Based on the principle of the Jameson flotation machine, injection velocity of ore pulp affects significantly on the recovery efficiency of both coarse and fine particles. For recovery of finer particles, smaller air bubbles are required and higher injection speed should be generated in comparison to coarser size particles. Injection speed in turn depends on many factors including feed pressure, pulp flow rate, diameter of the injection pipe, and size and form of the pulp injection head. This paper presents results of the study into recovery efficiency of different sized coal particles by using Jameson cell flotation. In the experiments, unsized and sized samples were used for flotation at a set of different injection speeds. From the study results, the suitable flotation operating conditions and some structural parameters of Jameson cell for the cases of fine and coarse particles recovery were determined
