A closed loop mineral cycle refers to a system where minerals are continuously recycled and reused within a specific ecosystem or environment. This process involves the efficient use and management of minerals to minimize waste and ensure sustainability. By closing the loop on mineral cycles, resources are conserved, and the environmental impact of extracting and disposing of minerals is reduced. This approach promotes a circular economy where materials are reused and recycled to create a more sustainable and efficient system. **
