The phosphate ion is a polyatomic ion with the empirical formula PO 3− 4 and a molar mass of 94.97 g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. The phosphate ion carries a −3 formal charge and is the conjugate base of the hydrogen phosphate ion, HPO 2− 4, which is the ...

As a mineral resource, "phosphate rock" is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.

Phosphate Rock Concentrate what does fertilizer "analysis" mean? All fertilizers have three numbers on the label which indicate the fertilizer analysis or "percentage by weight" of nitrogen phosphorus and potassium in that order.

The price that a producer can obtain for phosphate rock concentrate is mainly dependent on the percentage of P2O5 contained in it. The price quoted for Moroccan phosphate rock concentrate is representative of the price that would apply for Stonegate's phosphate rock concentrate because of expected similarity in P2O5 content.

leaching. Phosphate leached from guano phosphatizes the underlying rocks in some areas, forming apatite where the host rock is limestone and forming aluminum- or aluminum-iron-phosphate minerals where the underlying rock is a silicate. Individual deposits of both igneous apatite and marine phos­
