The mining industry faces increasing challenges concerning water management, whether due to resource shortage in the exploitation area, or with the aim of improving economic and social impact of the mining operations facing increasingly lower mill head grades and thus requiring more efficient operations.
With the abovementioned challenge in mind, we support the mining industry by developing innovative solutions that allow process water optimization, water reuse, and consequent minimization of economic impact water has in the process, furtheron improving relationship with social actors and stakeholders.

We are able to deploy specific solutions to treat different kinds of water sources, either surface or subsurface water.

The beneficiation stages involve several processes, including flotation and leaching, requiring specific technologies in order to obtain a high mineral law.
Adequate treatment of wastewaters generated in the flotation or leaching process require custom solutions to allow removal of different pollutants, making it necessary to develop integrated solutions involving both equipment and chemical technologies that can successfully remove soluble and suspended contaminants.

Treatment and reuse of mine tailings presents specific challenges due to its high variability and different types of contaminants, therefore requiring a high-level approach to identify individual upstream processes affecting global water balance, until final plant discharge or water reuse objectives are achieved.
|5||Acid Mine Drainage|
Acid mine drainage (AMD) is the appearance of highly acidic water streams averaging pH values of 2-4, and high concentrations of metal ions as a result of subaerial exposure during metal sulfide mining. AMD requires the use of specific technologies suited for operation under extreme pH conditions and high inorganic contaminant loads.
Selective leaching processes have made important progress with the objective of achieving higher yields during metal ore beneficiation, reducing reagent costs and maximizing leaching agent reuse. WET has developed strategic alliances to improve beneficiation processes in order to achieve a positive impact on mineral efficiency and productivity.
