Integrated 3D geo-environmental assessment of acid-forming materials in historic coal waste piles for sustainable management.

Coal mining produces coal mine waste rock (CMWR), posing significant environmental risks, including acid mine drainage (AMD) if unmanaged. The Jerada Mine in eastern Morocco has accumulated CMWR since it began operations in 1936, with no rehabilitation efforts until 2001. This study assessed the stability of the T08 pile, which has been deposited over five decades across various oxidation zones.

Sustainable phosphate mining: Enhancing efficiency in mining and pre-beneficiation processes.

Phosphate holds a critical role as a vital, limited, strategic, and irreplaceable resource. Throughout its production chain, residual phosphate can be found in waste streams. This study aims to enhance production efficiency by exploring methods to limit residual phosphate presence in waste stocks.

Native plant diversity for ecological reclamation in Moroccan open-pit phosphate mines.

Mining activities have significant impacts on the environment, particularly in terms of the destruction of natural habitats andbiodiversity loss. With the increasing awareness of the importance of ecological restoration and conservation, there is a growing need to study and understand the flora that thrives in mining sites in order to facilitate successful reclamation efforts. This study aimed to investigate the floristic composition and plant diversity of four phosphate mine sites (PMSs) in Morocco, namely Bou Craa mine (BCM), Ben Guerir mine (BGM), Youssoufia mine (YSM), and Khouribga mine (KHM).

Characterization of plant growth promoting activities of indigenous bacteria of phosphate mine wastes, a first step toward revegetation.

Morocco holds the vast majority of the world's phosphate reserves, but due to the processes involved in extracting and commercializing these reserves, large quantities of de-structured, nutritionally deficient mine phosphate wastes are produced each year. In a semi-arid climate, these wastes severely hamper plant growth and development leading to huge unvegetated areas. Soil indigenous Plant Growth-Promoting Bacteria (PGPB) play a pivotal role in restauration of these phosphate mining wastes by revegetation, by increasing plants development, soil functioning, and nutrient cycling.
