The production of superphosphate consists of three distinct steps. See the process flow diagram (Figure 4). Step 1 - Phosphate rock blending and grinding Phosphate rock from different sources have different phosphate, fluoride and silica contents.

1.Blending and grinding of Rock Phosphate. Depending upon its origin, the mineral content of phosphate rock varies. The phosphate rocks are mixed in the blending plant to produce a product of 15% phosphorus concentration. The particle size is reduced by passing the mixture through a hammer mill which converts particle size to 0.5 cm or less.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.

Phosphate rock plays an important role in China's national economy and collophane accounts for about 75% of the world's total phosphate rock reserves [].China is the second largest phosphate rock resource country in the world with 3.2 billion tons of phosphate rock resources [].Sedimentary collophane accounts for more than 80% of the total phosphate reserve and siliceous …Chapter 4. Evaluation of phosphate rocks for direct application. Chapter 3 described the characterization of phosphate rock (PR) materials for direct application. Depending on their origin and geological history, PRs show great variability in their inherent properties, especially in their grade, beneficiation requirements and apatite reactivity.

Phosphate rock preparation generates some dry particulate matter during drying, grinding, and transferring of the rock. These emissions are controlled by wet scrubbers and baghouses. The atmospheric emissions and control methods for the production processes are shown in Table 31.7 .Total biomass (dry weight) per plant ranged from 16.2 g in rock phosphate control to 48.8 g in PSB + T. harzianum + rock phosphate + Rhizobium treatment . Biomass in control plots (plots without any microbial inoculation but with normal fertilization) was 21.7 g, which was significantly lower than the biomass in plots where PSB and/or ...
