Basic and Detailed Engineering Project Cost Estimates and Technical Evaluations for the Purchase of Equipment for the Acid Water Treatment Plants (AWTP) at La Quinua and Pampa Larga for Minera Yanacocha.

The plants are located at an altitude of 4,000 masl., with temperatures between 0°C and 22° C and winds up to 120 km/hr. The AWTP Plants regulate the pH levels and remove heavy metals before being discharged to the environment. Before treatment, water contains the following metals: Aluminnum, Manganese, Iron and lower concentrations of Copper and Zinc.

The engineering design included an Acid Walter Intake, a collection and Transport System, Clarifier Tanks, a Sludge Clarifier System, a Chemical Dosing System and Transfer Pumps. Engineering was developed in a 3D environment using PDMS.
