Recent Trends in Phosphate Mining and Beneficiation and Related Waste Management by Mostafa Benzaazoua,Yassine Taha Pdf

The extraction of apatite minerals is becoming more and more crucial with the depletion of high-grade ores. At the same time, many streams of waste are continuously being produced by the phosphate industry, including calcareous and siliceous waste rocks, clayey sludge and phosphogypsum. These waste products are produced in huge volumes reaching a ratio of between 5 to 10 tons of waste per each ton of concentrated phosphate. The management of these waste products is becoming a real issue in terms of growing public awareness and environmental and financial aspects. In addition, phosphate ores are known to contain other critical raw materials (CRM) such as rare earth elements and uranium. The recovery of these vital elements from phosphate waste may help to develop the needs of the green energy of the future and contribute to the achievement of the sustainable development goals. In this Special Issue, insights related to the following aspects were studied: phosphate extraction and beneficiation, novel phosphate ores, the fine characterization of phosphate ores and waste, phosphoric acid production, critical raw material (CRM) recovery from phosphate ores and waste, reprocessing of phosphate wastes and finally the valorization and reuse of phosphate waste and phosphogypsum.

Beneficiation of Phosphates by Patrick Zhang,J. D. Miller,Hassan E. El-Shall Pdf

Fueled by climbing food prices, the demand for fertilizers is on the rise. The phosphate industry is responding aggressively by bringing significant projects on line across the globe. But meeting this unprecedented demand comes with a host of challenges: Environmental lawsuits have put a stop to one of the largest phosphate mines in the world. Other operations are closing because of the depletion of phosphate reserve. The increasing proportion of high organic and high dolomite ores has caused beneficiation costs to skyrocket. There is a growing urgency for the sustainable development and recycling of phosphate resources. Beneficiation of Phosphates: New Thought, New Technology, New Development provides a comprehensive look into how industry leaders and the R&D community are responding to these and many other critical issues. Dozens of internationally respected experts provide insights on key breakthroughs that are on the drawing boards or being implemented today that will shape the industry in the years ahead.

Beneficiation of Phosphate Ore by Kawatra, S. Komar,Carlson, J.T. Pdf

Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate). This wet process demands a phosphate rock feed that meets certain specifications to produce phosphoric acid efficiently and economically. Beneficiation of Phosphate Ore thoroughly explains the methods used in beneficiation of different types of phosphate ores for use in the wet process. The mineralogical properties of the two major types of phosphate deposits, sedimentary and igneous, are described along with the processing methods. The benefits and disadvantages of each process are discussed in detail.

Sustainable and Economic Waste Management by Hossain Md Anawar,Vladimir Strezov,Abhilash Pdf

This book compiles research findings directly related to sustainable and economic waste management and resource recovery. Mining wastes and municipal, urban, domestic, industrial and agricultural wastes and effluents—which contain persistent organic contaminants, nanoparticle organic chemicals, nutrients, energy, organic materials, heavy metal, rare earth elements, iron, steel, bauxite, coal and other valuable materials—are significantly responsible for environmental contamination. These low-tenor raw materials, if recycled, can significantly address the demand–supply chain mismatch and process sustainability as a whole while simultaneously decreasing their impacts on human life and biodiversity. This book summarises the large volume of current research in the realm of waste management and resource recovery, which has led to innovation and commercialisation of sustainable and economic waste management for improved environmental safety and improved economics. Key Features: Reviews the key research findings related to sustainable and economic resource recovery and waste management techniques Discusses minimizing waste materials and environmental contaminants with a focus on recovering valuable resources from wastes Examines the potential uses of mining waste in the re-extraction of metals, provision of fuel for power plants, and as a supply of other valuable materials for utilisation/processing Presents research on recycling of municipal, urban, domestic, industrial and agricultural wastes and wastewater in the production and recovery of energy, biogas, fertilizers, organic materials and nutrients Outlines topical research interests resulting in patents and inventions for sustainable and economic waste management techniques and environmental safety

Waste Production and Utilization in the Metal Extraction Industry by Sehliselo Ndlovu,Geoffrey S. Simate,Elias Matinde Pdf

"Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain. This book reviews current status and future trends in the recycling and reuse of mineral and metal waste and also details the policy and legislation regarding the waste management, health and environmental impacts in the mining, beneficiation, metal extraction and manufacturing processes.This book is a useful reference for engineers and researchers in industry, policymakers and legislators in governance, and academics on the current status and future trends in the recycling and reuse of mineral and metal waste. Some of the key features of the book are as follows:Holistic approach to waste generation, recycling and reuse along the minerals and metals extraction.Detailed overview of metallurgical waste generation.Practical examples with complete flow sheets, techniques and interventions on waste management.Integrates the technical issues related to efficient resources utilization with the policy and regulatory framework.Novel approach to addressing future commodity shortages."--Provided by publisher.
