More2024.2.9 During this process, much of the phosphate values are lost to the tailings stream. For example, to obtain 1 ton of rock containing 31% P 2 O 5, about 6.5 tons of waste containing 1.69% P 2 O 5 must be discarded to the tailings impoundment (Figure 1). The industry is also burdened with importing elemental sulphur, manufacturing sulphuric acid ...
More2022.12.25 The form of a phosphate mine waste rock pile depends on two criteria: the disposal method (top-down or bottom-up) and the land surface (flat or horizontal) (Blight, 2009).Different configurations of the mentioned criteria are illustrated in Fig. 3.The top-down disposal method involves discharging waste rock over an advancing face (Fig. 3 A–C

More2022.12.25 Introduction. Phosphorus (phôs: light and phoros: bearer in Greek), which is an essential element for all life forms, is a major and vital non-renewable resource (Elbendary et al., 2019; Sis and Chander, 2003).Phosphorus was discovered by Henning Brand in 1669 (Huminicki and Hawthorne, 2002). Phosphate rock is mainly used as a
MoreChemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
MorePhosphate rock sources may be of igneous or sedimentary origin. Results: In Egypt, the natural phosphate rock is located in Sebaiya (Nile Valley), Safaga (Red Sea), and Abu Tartur (Western Desert). The higher the organic matter contents in soil, the better dissolution of the PR. Legumes are particularly suited for the use of PR.
