Tailings and gangue are the Uneconomic Remainder from mining; as mining techniques and the price of minerals improve it is not unusual for tailings to be reprocessed using new methods or more thoroughly with old methods, perhaps to recover minerals other than those originally mined. In Coal Production and Oil Sands Mining , the word 'tailings' refers specifically to fine waste suspended in water and the word 'gangue' is never used. EFFECTS ON THE ENVIRONMENT Certain types of extraction methods, like , like Newmont Mining , Placer Dome , Rio Tinto Group and BHP Billiton , have come under attack for operating or planning STD at mines throughout the Asia-Pacific region. Often, as in the case of riverbed metal Extraction , this has buried valuable river-flat Soils under the largely worthless and often Contaminated tailings. Modern extraction methods have resulted in less damage but Land Rehabilitation continues to be a major problem and costly consideration. COMMON CONTENTS OF TAILINGS EXTERNAL LINKS
