Other REE deposits include monazite placer deposits (river and beach sands), iron-oxide-copper-gold deposits, and ion-absorption clay deposits. Global REE production is dominated by one country: China. China is estimated to contain 36% of the world’s REE reserves. In 2019, China produced 132,000 tons of REEs, 63% of the world’s supply.
