This study investigated the effect of calcination on 6 apatite RPs (Christmas Island Aore, Egypt, Morocco, North Carolina, Queensland, and Sechura). RPs were uncalcined (25 degreesC) and calcined at 500 degreesC, 900 degreesC, and 1100 degreesC. They were evaluated by Xray diffraction (XRD) and BETN2 surface area technique.
Christmas Island Rock Phosphate (CIRP) is known to cause renal fibrosis and depressed growth performance when it is used as a source of calcium and phosphorus in grain based rations for grower pigs. As a result its full potential as an inexpensive mineral supplement has not been realised. This thesis presents a 4 part study of the toxic effects of CIRP and investigates the economic feasibility ...

Christmas Island Rock Phosphate (CIRP) was formed by slow phosphatisation of the parent sedimentary and volcanic rocks over millions of years. The Island is made up of volcanic rocks interbedded with coral limestone, and has been subjected to several phases of uplifting, forming a central plateau at an elevation of 200350 metres above sea level.

Phosphate is not a rock. It is: A salt or ester of phosphoric acid. A fertilizer containing phosphorus compounds. A soda fountain drink made by blending carbonated water with flavored syrup.
Christmas Island rock phosphate has been used as a P supplement for lactating cows, despite a fluorine content of 15 g/kg (Snook, 1962). When fed over 4 yr at a rate of 50 g/day, butterfat production was doubled although the fluorine content of the ash of the metacarpus increased to 3000 mg/kg compared with 500 mg/kg for the control.
The phosphate ion is a polyatomic ion with the empirical formula PO3− 4 and a molar mass of g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetredral arrangement. The phosphate ion carries a negative three formal charge and is the conjugate base of the hydrogen phosphate ion, HPO2−
Murdoch University and Christmas Islands Phosphate (CIP) to evaluate the scientific basis for the introduction of agriculture to Christmas Island. This report presents experimental data that validates the suitability for legumebased agriculture at five sites on Christmas Island previously mined for apatite.
I think that there are 2 types of rock phosphate. One is hard rock phosphate (not very useful for produce) and the other is soft rock phosphatethe soft rock that we apply is called CalPhos and I think that it''s 030 (3% available and 20% total). It is a brown, granular material which softens up when wet.

The objective of this work was to develop and evaluate a soil test suitable for estimating the phosphorus status of soils whether they were fertilized with soluble or sparingly soluble P fertilizers or both. Four New Zealand soils of contrasting P sorption capacity and exchangeable Ca content were incubated alone or with monocalcium phosphate (MCP), reactive North Carolina (NC) phosphate rock ...
Christmas Island, Australia (10°26 S, 105°41 E) is located in the northeastern Indian Ocean ().The island is volcanic in origin, encompassing an area of 135 km Island is a basaltic seamount, following a series of geological uplift events, it emerged from the ocean approximately 10 million years ago (Borissova, 1994; Grimes, 2001).

Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock that contains high amounts of phosphate phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O occurs through washing, screening ...

16 "C"gradeChristmas Island phosphate base rock. At Christmas Island the phosphate has been derived from guano, and subsequent laterisation has resulted in concentration of the iron and aluminium oxides and the formation of a variable mixture containing .
In the case of PRs where phosphate has been substituted with carbonate ions, hydrogen ions may also be needed to neutralize hydroxyl ions formed on the release of carbonate ions into solution (Chien, 1977b). Each carbonate ion (CO 3 2) joins with two hydrogen ions and forms one water molecule and carbon dioxide gas. Thus, an adequate supply of ...
An application rate of 15–20 t ha 1 of RS compost together with 130 kg ha 1 urea, 200 kg ha 1 Christmas Island rock phosphate, and 67 kg ha 1 muriate of potash are recommended to improve the soil NPK contents and growth of Zea mays in acidic soil.
