however,” the study clarifies. “These applications and their metals are only just being put on the market and will not be available for recycling for the next 10-15 years.”.
Phosphogypsum (PG) is a solid waste product of the wet-process phosphoric acid industry that accumulates in large amounts on the ground, forming PG ponds. In recent years, the amount of PG produced and discharged into ponds has increased significantly with the increase in the market demand for...

Therefore, it is very critical to realize the harmlessness, recycling and reduction of PG [3,4,5]. Resource utilization is one of the key ways for effective PG utilization at present. However, due to the high impurity content, complex composition, radioactivity and low whiteness of PG, the...
REE extraction; waste materials recycling; alkaline leaching; Silius mine; Sardinia (Italy); circular economy1. Introduction A great variety of metals and minerals have an increasing importance for human development. In addition to the most common metallic elements, such as transition metals, iron ...
These elements have become indispensable ingredients in the global industrial revolution due to their unique properties such as high thermal stability, strong magnetism, and high electric conductivity. As a result, they are used in various applications in high-tech, green energy, military, and ...
According to the study on the criticality of raw materials and assessment [17], the European Union (E.U.) demonstrates a 4% of HREE recovery and 3% of LREE recovery through recycling these secondary resources. 1.2. Demand for REEs in the E.U. The increase in population across the globe ...
