Mining Milling Contaminated

Uranium Mining and Milling Wastes: An Introduction

2016-2-22  To keep groundwater out of the mine during operation, large amounts of contaminated water are pumped out and released to rivers and lakes. When the pumps are shut down after closure of the mine, there is a risk of groundwater contamination from the rising water level. ... Mining and milling removes hazardous constituents in the ore from their ...
