Mining may be the origin of environmental issues due to mineral extraction ore separation and transportation smelting and refining tailings disposal and wastewater disposal around mines Adriano 2001; Dongmei and Changqun 2008; Anda et al 2023; Akfas et al 2024 The disappearance of biodiversity and ecosystem function primarily as a consequence
Recent Trends in Phosphate Mining and Beneficiation and Related Waste Management Phosphate extraction and beneficiation is one of the vital mining industries in the world especially for the agriculture and food industries and a range of sulfuric acid solutions with pH values of 3 and 5 After drying wetting cycles unconfined
If the importance of phosphate as a mineral in humans life has pushed some authors to study the recovery of phosphate from wastewater Durrant et al 1999; Scholz and Wellmer 2019; Spears et al 2022 and some countries to extract phosphate at lower grades Ecoinvent Center 2007 then it is imperative for countries that hold this resource
The phosphate is sent to a chemical processing plant or fertilizer manufacturing plant Here molten sulfur shipped to Florida ports and trucked to the plant is used to create sulfuric acid The sulfuric acid is then mixed with the phosphate to make phosphoric acid The phosphoric acid is the main ingredient in fertilizer but can also be
Ma aden s Phosphate Mine produces close to million tonnes of ore per year while the Beneficiation Plant up to 5 million tonnes of concentrated phosphate rock per year Sulfuric Acid Plant Di Ammonium Phosphate Granulation Plant These plants make the Complex one of the largest phosphate production complexes in the world MWSPC

Recovery of light rare earth elements by leaching and extraction from phosphate mining waste Fluorapatite and Carbonate Fluorapatite Author links open overlay panel Z Hammache a 2 EthylHexyl Phosphate acid as extractant for Neodymium and Praseodymium a better extraction yield of 57% of the same elements was obtained with Tri Octyl
For the RP pathway the rock phosphate extraction mining and long distance transport from Morocco was included All other transport distances for NB1 NB6 were set to 25 km in the default scenario
Morocco with 70% of the world s phosphate reserves managed by OCP Office Chrifiens des Phosphates Amachraa and Quelin 2022 Bonini and Wesenbeeck 2023 Hakkou et al 2009 adopts circular growth for its environment and its communities while minimizing the environmental of mining sites and valorization of phosphate by product
Phosphate rock mining has led to rock desertification landscape modification loss of biodiversity dust and air pollution ground erosion ore extraction radioactive elements found in phosphate
This study explores a variety of approaches and techniques used by the fertilizer raw material mining industry in response to environmental challenges The study reinforces the fact that the environmental performance of the fertilizer raw materials industry has improved over recent decades although challenges remain
The hydrochloric acid route was firstly proposed by the Israeli Mining Industrials IMI [5] [6] The schematic diagram of the IMI hydrochloric acid route is shown in Fig 1 a The process includes the decomposition of phosphate rock with HCl solvent extraction of H 3 PO 4 and the purification of H 3 PO 4 by post treatment The key operation of the process is the
In this research the production of phosphoric acid and the recovery of uranium from the phosphate ore of the Sheikh Habil Iran mine has been investigated Flotation and calcination as pre treatment processes for the phosphate ore are used and optimized separately The pre treated phosphate ore was leached using sulfuric acid
To improve the sustainable management of phosphorus numerous LCA studies using primary data have been conducted for phosphorus recovery technologies from wastewater but not for phosphate rock article addresses this issue by conducting a cradle to gate assessment of beneficiated phosphate rock production using primary data This study aims to
In this work phosphate flotation tailings were upgraded by gravity separation and froth flotation Gravity separation was conducted using a laboratory shaking table while flotation was conducted in a Denver D 12 flotation cell The concentrated tailings were then leached by nitric acid followed by REE extraction with solvent and ion exchange
The anaerobic digestion is a sustainable technique to treat wastewater sludge for nutrient recovery producing digestate with a high fertilizer value Czekała et al 2020 Particularly the fermentation process effectively extracts P from solid sludge to the liquid phase of ferric phosphate sludge based on microbial processes
At OCP we re responsible for the world s largest phosphate reserves and everything we do feeds sustainable growth and brings phosphorus to life It begins with the right minerals From there come thriving crops Stronger communities Better business And more food for
