Anglo American’s flagship mine, Peru Quellaveco Copper Mine, approached JAD Design & Draughting to assist with modelling a total of 76 off froth sensors for their column cell, tank cell and molly plant areas. The froth sensors will form part of an Advanced Process Control (APC) system to help implement and maintain optimal processing recipes, particularly in the mine’s flotation circuit.
For the column cells, this involved designing an access walkway with a cat ladder and the mounting bracket for each froth sensor. The froth sensors on the tank cells required their own mounting brackets and an inspection hatch as they are positioned inside the tanks. Modification drawings for the existing grafting (to provide access to the froth sensors) were also provided. The tanks in the molly plant area contain hazardous gases, and so a seal between the froth sensor and the tank shell had to be designed, to prevent the gases from being expelled.
JAD’s expertise in 3D plant modelling ensured correct design of all the froth sensor brackets, such that no site modifications would be required, to prevent clashes. Having a 3D model also meant complete access to each froth sensor was allowed for, so that maintenance activities could take place with minimal effort from the maintenance team. The structural engineers at JAD ensured all local (Peruvian) and Anglo American design standards were adhered to.
