Dec 31, 2016 Some heavy mineral sands producers closed operations at low-grade ilmenite deposits to concentrate on deposits with higher zircon content or those more readily amenable to beneficiation. Ilmenite reserves have, however, increased 125 over the last 15 years from 25.1 Mt in 2002 to 56.5 Mt in 2016, after recovering from a post global financial ...

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.
