    摘要： A signal processor receives a signal containing information about a sensor that is spirally wrapped at a known pitch or separation down a pipe having a flow; and determines a flow velocity based at least partly on the information contained in the signal received by applying an autocorrelation function that depends on a relationship between the time between a repeating pattern and the known pitch or separation of the spirally wrapped sensor. The signal processor provides a corresponding signal containing information about the flow velocity. The sensor includes a strain sensor, including a piezo-electric polymer strain sensor fabricated from PVDF, and/or two or more equally spaced spirally wound sensors. The determining includes correlating output signals of two or more equally spaced spirally wound sensors to determine a time delay, and determining the flow velocity based on the time delay and the known pitch or separation.

    摘要： An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface. The filter, conveyor belt, collection plate and impeller may have a plurality of passage ways or synthetic beads in order to increase the contacting surfaces.

    摘要： Apparatus features an acoustic comb filter module configured to receive signaling containing information about different frequencies F1 and F2 to create a selected comb spacing D to capture certain particles having a selected size X in a flow stream in a flow pipe, and to provide an acoustic standing wave via ultrasonic excitation based at least partly on the two different frequencies F1 and F2 to create the selected comb spacing D to capture the certain particles having the selected size X in the flow stream in the flow pipe. The apparatus may also include a particle size or distribution determination module configured to receive the certain particles for off-stream analysis via a detection port that forms part of the flow pipe and determine the particle size or distribution of the certain particles in the flow stream in the flow pipe.
