define leachate in mineral processing

Landfill Leachate arises primarily as rainwater seeps through the landfill body, but also from the moisture inherent to the waste itself or – in the case of inadequately sealed landfills – groundwater ingression. Untreated leachate is a hazard to the environment if it is allowed to enter a body of water.
