Milling produces large chat waste piles and flat areas with tailings deposited in impoundments. Tailings generally contain higher concentrations of heavy metals and therefore present a higher risk to human health and the environment through direct contact. Chat typically ranges in diameter from 1/4 to 5/8 inch.
The Oklahoma Plan for Tar Creek claimed around 75 million tons of chat piles exist, while the exact amount of tailings is unknown. [8] It was not uncommon for children in the area to play around the chat piles, such as riding bikes up and down the large dune-like piles, or swimming in waters contaminated by chat dust or groundwater effects.
Thus an indication of these minerals being short in supply and allocated their title as 'rare' earth minerals. [4] Many rare-earth minerals include rare-earth elements which thus hold the same significant purpose of rare-earth minerals. [5] Earth's rare minerals have a wide range of purposes, including defense technologies and day-to-day uses. [6]

The Minerals, Metals & Materials Society (TMS) is a professional organization for materials scientists and engineers that encompasses the entire range of materials and engineering, from minerals processing and primary metals production to basic research and the advanced applications of materials.
The project consists of a permit of investigation (11.4 km 2) acquired by Technology Metals Europe SL in 2021. [9] The main target is a set of lithium-tantalum-niobium-tin-bearing aplite-pegmatite dykes. Of these minerals, the first three are critical raw materials for the EU, according to the list updated in 2020. [10]
The Moma Mine also produces zircon, an important raw material in the manufacture of ceramics, and mineral sands concentrates, which is used in various clean technology applications. [ 8 ] [ 9 ] The Mine is estimated to have a mine life of over 100 years at current production levels, with approximately 6.3 billion tonnes of Mineral Resources in ...
