Use of phosphate rocks for sustainable agriculture

The NAC P 2 O 5 solubilities of these PRs and a third rock increased from about 60 to 120 percent with grinding to minus 200 mesh. However, previous experimental reviews (Rogers et al ., 1953; Cooke, 1956; Khasawneh and Doll, 1978) concluded that any increase in PR solubility rarely justified grinding to a size less than 100 mesh for agronomic use.

Ammonium Phosphate - an overview | ScienceDirect Topics

The source of fluorides is phosphate rock, which contains from 3.5% to 4.0% (w/w) fluorine. The fluorine is generally precipitated out with gypsum, leached out with phosphoric acid product, or vaporized in the reactor or evaporator. The reactor where phosphate rock is contacted with sulfuric acid is the primary source of emissions.

The Role of the Mill in Fertilizer Manufacturing - Bradley ...

Most phosphate processors choose airswept milling systems due to their ability to remove fine particles from the grinding zone. Due to the cushioning effect from newly introduced feed, this allows the grinding action to be concentrated on the large oversize particles. This results in higher yields and, by minimizing overgrinding, lowers energy consumption.

Superphosphate - an overview | ScienceDirect Topics

A slurry of rock phosphate and phosphoric acid is made. Chemical reactions proceed towards completion in the fluid state. After 1 to 2 hours mixing period, the slurry is distributed over dry TSP material. The distribution is done in a rotary drum where granules are formed. The granules are dried, screened and cooled.

How phosphate is mined and processed

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
