Mitigating the environmental effects of opencast mining

Illegal mining must also be addressed as a part of an environmentally conscious mining solution. China in particular has many illegal mines that currently produce a significant share of the global supply of strategic metals. These mines also lack environmental, human rights, and quality standards. EnviroCopper are specialists in InSitu Recovery (ISR) of metals including copper and gold. InSitu Recovery (ISR) can provide substantial benefits over conventional mining in the right geological setting. ISR delivers a low cost method of mineral extraction with minimum environmental footprint without restricting land access.

Processes copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living. This is important not only for protection of the environment, but also because lost solutions means lost copper and less revenue. Good environmental control means copper resource conservation. Secondary hydraulic control A series of pump-out wells surround the leach system to draw water inward and downward into the mining system.
