 · 11.21 Phosphate Rock Processing 11.21.1 Process Description1-5 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding. The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. The ...

deposit was about 430 million tons of phosphate rock (Zainal, 1970; Al-Khalil et al., 1973). The mine was designed to produce 3.4 million tons/year with 21 – 22 % P 2

phosphate, and silica gel—were thoroughly mixed with the upper half of the sand in the pot prior to planting. The rock phosphate used was a Florida pebble rock ground to pass a 100-mesh sieve. It contained 31.63 per cent of total phosphoric acid. The acid phosphate contained 18.72 per cent of available and 19.74 per cent of total phosphoric acid.

 · Ore grade in the phosphate mining industry is one of the primary criterion used to differentiate phosphate ores. Grade is oft൥n expressed in terms of bone phosphate of lime ⠀䈀䰀 or phosphorus pentoxide ⠀㈀㔀. The use of BPL is from the outdated belief that P in PR existed as tricalcium phosphate.

 · The specific amount of tricalcium phosphate in a given material is sometimes expressed as bone phosphate of lime, or BPL. Rock phosphates are variable in phosphate content, containing anywhere from 15% (or less) to 36% total phosphate (P 2 O 5) with less than three percent available in a given year. Another form of mined calcium phosphate is ...

 · The chemical composition of phosphate becomes PO 4 under the name of BPL (Bone Phosphate Lime). Therefore, the next step consists of gathering all my information on the BPL material, as it is the ground form of phosphate. 1.1 Calculating S It's required for a phosphate assay to be accurate within ±1 % of phosphate (degree of confidence).

Phosphate deposits are of three main types: 1) Igneous Phosphate Deposits. 2) Biogenic (or Guano ; or Island) Deposits. 3) Marine Sedimentary Phosphate Deposits. 4 May 2016 Prof. Dr. …

 · Grade of Phosphate Rock. The phosphate rock industry does. not have a standard method for expressing the calcium phosphate content of phosphate rock. Three terms are in use: TPL -triphosphate of lime. P. 2. 0. 5 -phosphorous pentoxide. BPL - bone phosphate of lime. Triphosphate of lime is the compound, tricalcium orthophosphate ­ Ca. 3 (PO. 4 ...

 · ground phosphate rock with 65 to 75% sulfuric acid ( acid is preferred) (Mann 1992). The quality of phosphate rock is generally identified by its content of tricalcium phosphate (Ca3P2O8), called bone phosphate of lime (BPL). Chemical analyses are usually reported as the P2O5 percent (phosphoric acid) or percent of BPL (1% BPL = 0.485% P2O5).
