Abstract Sokoto rock phosphate (SRP) obtained from Sokoto in the Northern Nigeria was evaluated with some other phosphorus (P) sources viz: Partially acidulated rock phosphate (PARP) and single superphosphate (SSP) in the greenhouse and field studies. These fertilizers were also compared with nitrogen‐phosphorus‐potassium …Web
Phosphate Mineral Deposits - Africa has a wide range of phosphate minerals which are highly concentrated in Phosphate rocks and is found in Nigeria and the states that have the deposits include Sokoto, Abia, Imo, Edo, Anambra, and Ogun states.. It occurs in igneous and metamorphic rocks as a phosphate mineral such as fluorapatite Ca5F (PO4) 3, the …Web

Phosphate usually occurs as the mineral apatite, Ca5F(PO4)3 in igneous and metamorphic rocks. It may be derived from a number of sources but the most common is the one that contains high concentration of phosphates in nodular or compact masses. The Nigerian phosphate rock deposits are sedimentary in origin.Web
In Nigeria, the phosphate deposits are of the sedimentary, marine origin. In Sokoto State, phosphates of Paleocene sedimentary deposits occur in the Dange Formation.Web
Phosphate is an essential mineral that can be found in high volumes in phosphate rock from Ghana. This phosphate rock is a good source of nutrients that can be used to create high-quality fertilizer. The phosphate rock from Ghana is also less likely to contain heavy metals, like cadmium and lead. The high amount of phosphate in phosphate rock ...Web
The geochemical characterization of Sokoto phosphate rock in comparison to other phosphate rock deposits indicated that P 2 O 5 values range from 20.18-36.25 wt. ...Web

Ogun and Sokoto phosphate rock deposits were chosen out of four in Nigeria (Fig. 1) because they are found in commercial quantities (Obaje et al., 2014). Ogun State phosphate rock was collected from Oja-Odan, Ogun State, Nigeria with the assistance of a staff of the Geological Survey Department, Abeokuta, Ogun State, Nigeria (Fig. 2).Web
Rock phosphate was obtained from Sokoto state, Nigeria. Dolomite was obtained from Edo state, Nigeria. This work contains a detailed description of the procedure and the associated chemical reactions.Web

ABSTRACT The phosphorus (P) release characteristic of Ogun rock phosphate (OPR) acidulated with cashew nutshell liquid (CNSL), an industrial waste, was studied under laboratory conditions for ten weeks. The results showed that the acidulation of phosphate rock with cashew nutshell liquid at a ratio of 4 to 1 released the highest …Web
phosphate rock deposits provide 75% of the world's phosphate resources, while 15 – 20 % come from igneous and weathered deposits and only 1 – 2% from biogenic (mainly from and bat guano accumulations) resources (van Straaten, 2002). In Nigeria, the phosphate deposits are of the sedimentary, marine origin. InWeb
We converted elemental phosphorus to both phosphate rock and DAP fertiliser (rock 70% BPL ≈ 32% P 2 O 5; DAP = 46% P 2 O 5) and projected that, under …Web
This may be due to the presence of shale and possibly phosphate-bearing rock and metamorphozised granitic rocks while thorium has the largest deposit due to quarry activity which is associated with blasting of rocks and deposition from dumpsites. ...

Major and trace elements composition of phosphate rocks from phosphate bearing areas of Sokoto basin north-western Nigeria were investigated using PANanalytical Minipal4 PW4025/45B energy dispersive x-ray …Web
Phosphate rock, pre-concentrated phosphate ore, is the primary raw material for the production of mineral phosphate fertilizer. Phosphate rock is among the fifth most mined materials on earth, and it is also mined and processed to fertilizers in East Africa. Phosphate ore can contain relevant heavy metal impurities such as toxic …Web
