The objective of this research was to determine the influence of pH and agitation speed on the removal of zinc by alkaline precipitation in the waters of the Yauli River, La Oroya, the methodology was basic, quantitative approach, experimental scope - explanatory and factorial design. The results were that the turbidity and zinc parameters exceed the values established as quantification limits, while the pH and electrical conductivity values are lower than the ECA guidelines. On the other hand, it was also determined that when using slaked lime, the lowest concentrations of ORP were obtained with 120 mV, turbidity with 0.84 NTU and zinc with 0.08 ppm, with a removal efficiency of 81.67%; 99.46%; and 99.95% respectively, then it was also found that when using sodium hydroxide the lowest ORP concentrations were obtained with 92 mv, turbidity with 1.32 NTU and zinc with 0.15 ppm, with a removal efficiency of 85.95%; 99.15%; and 99.91% respectively, both treatments at a stirring speed of 100 rpm. Likewise, it was determined that the cost of treating water for clarification per cubic meter of effluent is S/ 62.3 for the process with sodium hydroxide and Lipesa 1547A; and S/ 3.40 for the process with lime and Lipesa 1547A. Finally, it is concluded that the agitation speed has a significant effect on the zinc removal efficiency, unlike pH, which has a lesser effect.
