Classification of Mineral Foam Flotation Conditions Based on
Accurate and rapid identification of mineral foam flotation states can increase mineral utilization and reduce the consumption of reagents. The traditional flotation process concentrates on extracting foam features from a single-modality foam image, and the accuracy is undesirable once problems such as insufficient image clarity or poor Based on researching into control technique of hematite flotation process, the mathematic model of control of flotation reagent quantum is introduced. This model uses image processing technique to extract texture characteristics of froth image before using the rough set and LVQ neural net technique to estimate the status of produce and adjust Application of image recognition system in flotation process

Flotation froth image texture extraction method based on
The experimental results demonstrate that the proposed method can extract froth image texture features accurately and provide effective guidance for flotation production. In the flotation process, the flotation froth texture is an indicator of the flotation state. To recognize the flotation state based on texture features accurately and to provide The visual parameters of the froth surface are significant to the flotation production statuses, but they are difficult to be measured with tradition image processing method for the froth surfaces are special complex grain fully occupied with various sizes of bubbles.
