Jun 02 2019 · Recycling isn’t economic for most rareearth metals unless of course prices rise Of course higher rareearth prices are a boon for smallcap mining stocks and the VanEck Vectors Rare Earth ETF may be a good investment for a time But that doesn’t mean the US economy has a rareearth
Some of the smaller rare earth smelting separation facilities do not have any kind of environmental protection at all These are generally the small illegal refineries and mines 6 In China saponification with ammonia is still used in rare earth refining so a large amount of waste water is still produced
Jul 15 2013 · ► Less than 1 of rare earths in endoflife consumer products are being recycled ► Recycling can help to ensure a supply of the most critical rare earths ► Valuable waste streams are magnets metal hydride batteries and lamp phosphors ► Recycling of neodymium avoids overproduction of cerium and lanthanum ► Recycling and primary mining of rare earths are complementary activities
