Codelco El Teniente Division is defining its water resources strategy in the short, medium and long term, in order to face the water crisis that the country is currently experiencing, climate change, possible changes in legislation and the requirements of the society.
Objective and scope
Identify technological solutions (equipment, chemicals, methodology and sensors) needed to reduce consumption – in tailings duct and thickener discharge.
The proposed technological solution should consider the following requirements:
Advisory services, consulting or engineering studies will not be considered in the background evaluation process.
Under current operating conditions, a solids percentage of 56 to 57% is achieved in the thickener discharge, given the rheological condition of the tailings and the current transport system to the tailings dam.
On dry years (Exceedance probability [AEP] 98%)
Under current conditions it is possible to increase the percentage of solids, affecting the reliability of the water recovery equipment.
No technological tests have been performed to date.
