The Effects Of Landfills On The Environment Sciencing

The Effects Of Landfills On The Environment Sciencing

As rain falls on landfill sites, organic and inorganic constituents dissolve, forming highly toxic chemicals leaching into groundwater. Water that rinses through these chemicals collects at the base of the landfill and usually contains high levels of toxic metals, ammonia, toxic organic compounds and pathogens.

Innovations: How Hydrometallurgy And The Sx/ew Process

In the United States, for example, the energy requirement for SX/EW processing of heap or dump leaching ranges from an estimated 10 MJ/kg to 25 MJ/kg - the difference being largely the pumping costs. In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant.
