Froth flotation is an effective process for separating valuable from gangue minerals. Studies show that the performance of froth flotation is affected by the froth structure, and has a strong relationship with visual information of the froth surface. The determination of the froth structure, therefore, plays a vital role for controlling the process. Extensive studies have shown that computer-based vision technology is a robust, non-intrusive and cost effective approach for monitoring and controlling of flotation c...

The main goal of a small scale stream sediments geochemical survey is to identify the promising areas for the further exploration in next steps of geochemical exploration. To achieve the target the thresholds value of each interested element within the geochemical sample must be specified at the first step. In this research it is attempted to use the raw geochemical data after pre-processing to delineate the anomalous area within the Khusf 1:50000 sheets which is located at 35 km west of Birjand at the south khora...
