The circular economy has become an increasingly popular trend in addressing the environmental and economic challenges of today's world. Instead of following a linear model of production and consumption, circularity proposes closing the life cycle of materials and resources, keeping them in use for as long as possible, and minimizing waste and pollution. The implementation of circular practices can bring significant environmental, social, and economic benefits, and in this sense, the challenge arises of how to valorize resources and waste generated in the production process to reduce environmental impact and maximize efficiency and profitability. This challenge is particularly relevant in the context of mining in Peru, where extractive activity is an important part of the economy but also has a significant impact on the environment and local communities.
**Value elements** Mining companies are looking for technologies that consider one or more value elements in their proposal. Solutions focused on the valorization of effluent water in the influence zone. Solutions that decrease or partially or totally replace the use of lime in metallurgical and water treatment processes. Technologies that extend the life use of critical inputs: mill steel balls, tires, equipment oil, etc. Use of non-contact water (which has not been touched by the metallurgical mining process, for example, rainwater). Alternatives for injecting water into the aquifer in times of excess rainfall. The revalorization of rejection water (water that contains salts, filtered from the treatment plant), without causing pipe scaling. Solutions focused on the recovery of remaining mineral grades. Solutions focused on the revalorization of tailings with non-metallic mineral concentrations (pyrite, carbonates, silicates, etc.). The revalorization of organic waste for energy generation or contribution to agriculture or other activities. The revalorization of sludge by acid water treatment.
