The continuous operation of the 2nd – 3rd and 3rd – 4th crushing stages at the Codelco Andina Division concentrator plant depends on the supply of ore from different stocks located at intermediate points, so it is essential to maintain adequate control of their filling level. It is important to consider that these stocks correspond to ore disposed on live rock with gravitational discharge, generating dead load rings and segregation of the material as it is discharged. At the same time, the material causes erosion of the walls of the stocks, so their geometry and storage capacity are variable.
Currently, the measurement of the filling level of the intermediate stocks is done manually, which generates uncertainties for the autonomy of the process in the event of plant stoppages and has a direct impact on the efficiency of operational decisions.
In addition, this manual maneuver requires the allocation of human resources that are exposed to the risk of accidents at each measurement.
Technological solutions are sought that allow online measurement of the level of ore filling in intermediate stocks of crushed ore.
The scouting process could lead to the identification and selection of suppliers for a supply or purchase process, whose scope will be defined according to the degree of maturity of the proposals that apply to the open innovation process, which could lead to a pilot validation test, or to an implementation if they are relevant and meet the evaluation and selection criteria defined by Codelco.
The measurement of the filling level of intermediate stocks that feed the different crushing stages is done manually. It is necessary to identify technological solutions that allow delivering their fill level online.
At the beginning and end of each shift.
Manual measurement with rope and plumb bob, and also ultrasonic radars.
The following will not be considered in the background evaluation process:
