Book Description
"For every problem there is a solution--simple, neat, and wrong." H. L. Mencken made this observation years ago, and it is quoted at the beginning of Fred Blakey's study of Florida's phosphate industry. Few people would disagree that there is a real environmental crisis facing the world today. The cause is unrestrained growth of the population, of economies, and of the exploitation of natural resources. The author points out that this viewpoint is foreign to a people who have equated growth with progress, and bigness with goodness. Only recently have Americans conceded that their resources are not inexhaustible. Blakey tells us that we have been bombarded with solutions to a problem that professionals view as not yet fully understood nor adequately defined. Americans face the problem not only of pollution, but of management, of values, of their very way of life. If the earth is to provide the materials for the survival of man's society, then a prudent society must provide for an intimate understanding of the earth. Phosphorus, the topic of this study, is an element necessary for all forms of life. Long before carbon, nitrogen, or oxygen supplies become critically short, the supply of phosphorus will be exhausted. When this happens, Blakey assures us, life will end, and he demonstrates that we are losing ever-increasing amounts of this vital element every year. This work presents a microscopic view of the ecological problems and prospects in the conservation and use of the mineral. Specifically, it is a history of the Florida phosphate industry. If the record of the Florida phosphate industry is any guide, then ecological disaster need not occur, but enlightened use of phosphorus and all other natural resources would seem to be imperative. The author tells us it is necessary to redefine some of our traditional priorities, beliefs, and values. Failure to do this indicates a willingness to continue to accept solutions that are "simple, neat--and wrong."

Book Description
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.

Book Description
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.
