**Caso: Reaprovechamiento de agua ácida proveniente de los efluentes del depósito de desmonte DD2**



**Nombre de la empresa minera: **La Arena S. A.
**Nombre de la unidad minera: **La Arena
**Nombre y cargo del funcionario minero: **César Augusto Espejo Rodríguez, Gerente de Procesos
**Periodo de ejecución:** octubre 2024 – diciembre 2025



**Problema**

Alto consumo de cloruro férrico como coagulante principal en sus procesos de tratamiento de agua.



**Solución**

- -Se evaluó la viabilidad técnica de utilizar agua ácida del DD2, considerando sus características.
- -El proyecto fue comunicado al personal operativo y de supervisión, explicando los objetivos y beneficios.
- -Se trasladó agua ácida desde el DD2 hacia Planta DETOX utilizando contenedores IBC, permitiendo su dosificación controlada.
- -Se mejoró la frecuencia de traslado y se automatizó la dosificación para asegurar mayor estabilidad operativa y mayor eficiencia.
- -No se requirió inversión adicional o compra de equipos, las mejoras se desarrollaron con recursos existentes, que no afectaron el costo operativo.
- -Se realiza monitoreo continuo de la calidad del tratamiento y del ahorro generado. Se evalúa escalar el sistema con mayor automatización y replicarlo en otras plantas.



**Impacto**

Ahorro acumulado en el primer semestre de USD 53,000.

Context

In a group of mining companies in Bolivia, there was a need to improve real-time remote monitoring of tailings dams. These sites were already equipped with auscultation systems, such as piezometers and seismographs, but they lacked remote data transmission capability.

Tailings dams, which are critical infrastructures in mining operations, pose significant risks due to potential water seepage or natural events that may compromise their integrity. To mitigate these risks, it is essential to have a monitoring system that provides real-time information on the dam's condition.

Challenge

The client sought a comprehensive solution that would enable continuous remote monitoring, facilitating decision-making based on accurate and up-to-date data.

The required solution had to provide internet connectivity for existing equipment, a centralized platform for data storage and visualization, and remote access for diagnostics and maintenance tasks. All of this was crucial for the safety and efficient operation of the mines.

Solution

GIE GROUP designed a comprehensive IoT-based instrumentation and monitoring solution called GIE CLOUD. The process included surveying and specifying instrumentation requirements, monitoring system engineering, provision and installation of instrumentation, data acquisition, transmission, storage, and visualization.

GIE CLOUD, developed by GIE GROUP's Digital Transformation department, is an IoT platform that manages internet-connected devices, facilitating data collection, processing, and analysis. Its main features include connectivity, device management, data collection and storage, and data processing and analysis.

GIE CLOUD significantly improves tailings dam monitoring by unifying real-time information query and visualization from anywhere, regardless of the technology and/or type of monitoring devices used.
