Machine-vision-based control of zinc flotation—A

2006-12-1  The bubble load variable has proven to be the best indicator of the zinc flotation performance. Therefore, the data were classified on the basis of the bubble load into 13 classes. Fig. 8 shows the zinc recovery as a function of the bubble load. The figure also shows the corresponding class averages of the zinc grade of the circuit feed and the froth speed.

The lead-zinc oxide and the gangue minerals are intricately inlaid, intersecting each other. During the flotation process of lead-zinc oxide ore, sulfides should be added to sulfide the minerals to facilitate the subsequent flotation treatment. The following issues need to be paid attention to during the sulfidation treatment of lead oxide ore: First, white lead ore, lead alum and molybdenum lead ore are easier to

This is due to the fact that plant operators use the froth appearance as one of the main indicators when they monitor and optimize the running of the flotation process. Hence if the operator's work could be supported or partially automated using a machine vision system and feedback control, considerable improvements in flotation performance could be expected.

In conclusion, this study demonstrated that it is significantly more likely that the centrifugal flotation in zinc sulphate solution detect a faecal sample positive for T. trichiura or E. vermicularis than the centrifugal sedimentation process, whereas there were no significant differences between methods in the identification of other intestinal parasites, including G. duodenalis. Therefore, the use of both methods

Determination of maximum zinc recovery of Vazante

As expected for a flotation with high zinc recovery, the main components of the tailings are minerals that do not have zinc in their composition: Dolomite - CaMg(CO 3) 2 - that comes from the hosted rock Dolomite and Hematite - Fe 2 O 3 - that is not recovered in the flotation process, concentrates itself in the tailings. The set of zinc minerals has little participation in the tailings and shows a good efficiency of the zinc flotation
