As terras raras são um grupo de 17 elementos químicos fundamentais para a fabricação de tecnologias modernas, como smartphones, turbinas eólicas, baterias, equipamentos médicos e sistemas de defesa. Apesar do nome, não são escassas, mas ocorrem em concentrações baixas, o que torna sua extração e separação desafiadoras. A China é o principal país produtor e detém mais de 60% da produção mundial. #terrasraras #geografia #curiosidades
