Environmental impact and management of phosphogypsum

Environmental protection is a complex systematic problem and therefore when designing industrial operations and processes in Elixir Prahovo we are striving towards systematic solutions to the environmental impact issues The preservation of the environment is a daily commitment of all the employees in Elixir Prahovo Red and brown muds are the secondary materials generated from the extraction of alumina from bauxite an aluminum-containing sedimentary rock (Ref 2) Phosphogypsum is the secondary material generated by the phosphorous fertilizer industry from phosphate-containing sedimentary rock (Ref 3) These materials were directly discharged to water bodies until the mid-1970's

The present work is directed to the characterization of the phosphogypsum (PG) solid waste which accompanying the production of phosphoric acid by the wet process in Abu Zaabal company for fertilizers and chemicals production in Egypt Samples from PG were characterized radiometrically using both

Environmental resource permitting standards are detailed in Part IV of Chapter 373 F using best management practices and other measures to protect areas that will not be mined and putting systems in place to offset impacts to water levels and flow in surrounding areas Following clearing and site preparation large draglines are used to conduct the mining The dragline bucket holds from

Although phosphogypsum is mainly calcium sulfate dihydrate it contains elevated levels of impurities which originate primarily from the source phosphate rock used in P fertilizer production The main environmental concerns associated with phosphogypsum are: (i) movement of fluoride sulfate total dissolved solids certain trace elements and radionuclides from the U-238 decay series below

Phosphogypsum is the gypsum as a byproduct It caused serious environment pollution In this study leaching As of phosphogypsum was studied by leaching equipment of self-made We get some results of As heavy metals of the phosphogypsum affect the soil The results show that: the content of arsenic is increasing and the pH of the soil is gradually decreased with the increasing of the leaching

Phosphogypsum recycling The land consumption huge expenses and endless monitoring required for environmental isolation of the phosphogypsum tailings implies that conversion to a useful product even without a significant profit margin is a preferable option in environmental management It has been shown that the phosphogypsum is comparable to ordinary gypsum and can be used as

The list of environmental concerns that can be connected with rare earth elements is not a brief one Throughout the cycle of mining processes that rare earth elements go through there is potential for negative effects on the environment Extracting rare earth elements begins with mining This is followed by the refining process and then disposal All of the stages of mining refining and

The radionuclides present in phosphate ore phosphogypsum and soil samples in the vicinity of a phosphate fertilizer plants in Nigeria were identified and their activity concentration determined to assess the potential radiation impact on the environment due to fertilizer production The mean activity concentration of 238 U 232 Th and 40 K radionuclides in phosphate ore samples were 616

A new kind of high strength cementitious material is made from phosphogypsum (PG) active carbon and fly-ash Through the orthogonal research it was showed that the calcination temperature retention time dosage of active carbon and fly ash on the compressive strength of cementitious binder are the most important The result also showed that in the conditions of temperature 1200C time
