Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals.The 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 5.This occurs through washing, screening ...
• Gradual release of phosphorus provides a residual effect in the soil • Provides high levels of phosphorus and calcium, and adds bulk to soil Sechura Reactive Phosphate Rock (RPR) from Peru is a natural, gradual-release source of phosphorus that can be applied directly to crops. RPR produces
Most of the world production of phosphate rock is used as fertilizer. As a major global agricultural exporter, Brazil must import the minerals needed to feed its giant production system (purchases totaled US$9.1 billion in 2013, according to official sources quoted by EFE).
Phosphorus is essential to plant growth, but there's a looming shortage, which could leave global agriculture without the fertilizer needed to feed growing populations. Some scientists think, with some tweaks to our sanitation system, human urine could be mined for the necessary phosphorus.
Apr 25, 2017· Phosphate ore is a mineral and is a natural source of Calcium Phosphate. It mainly consists of Calcium Phosphate and Calcium Fluoride. There are also hazards of over use of Calcium Phosphate as it leaches surface minerals from soils and when these nutrients seep into water supplies, they lead to over growth of algae.
Tricalcium Phosphate (TCP) is used as an anti-caking agent in dry vinegar and salts. It is often used as an additive for milk powder, pudding and various types of flavoring. It's also used as a calcium source for cereals and is a nutrition enhancer.

Phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates.. The thickest deposits of phosphorite form in areas characterized by carbonaceous shale and chert.
The δ 18 O P values of detrital phosphate, which vary from 7.7–15.4‰, suggest two possible terrigenous sources and their mixtures in different proportions: phosphate from igneous/metamorphic rocks and phosphate precipitated in source regions in equilibrium with δ 18 O w of meteoric water.

The predominant source of phosphorus in modern times is phosphate rock (as opposed to the guano that preceded it). According to some researchers, Earth's commercial and affordable phosphorus reserves are expected to be depleted in 50–100 years and peak phosphorus to be reached in approximately 2030.
Peru is the world's second-largest producer of silver, sixth-largest producer of gold and copper, and a significant source of the world's zinc and lead. Mineral exports have consistently accounted for the most significant portion of Peru's export revenue, averaging around 50% of total earnings from 1998 to 2005 and 62% in 2006.
One source of future phosphate production is offshore deposits. Deposits of this type occur along the southeast coast of the United States of America, on the Peru-Chile shelf, off the coast of Namibia, on the Chatham Rise off New Zealand, off the coast of Baja California, Mexico, and off the Congo River delta.
