Come see our own Ian Hancock, VP Sales and Operations at Bradley Pulverizer, deliver his technical innovation presentation focused on the “Use of Low Grade Phosphate for Superphosphate Production”, at the CRU Phosphates 2024 Conference & Exhibition in Poland on Feb 27, 2024 from 12:15-12:45.
This presentation looks at how the decline in the quality of available phosphate rock sources is affecting the ability to produce high grade superphosphate fertilizers, even after beneficiation after mining (Fertilizer International 517, p53). Rock quality is also becoming a key consideration due to concerns about cadmium build up in soils. High silica levels in some rocks, meanwhile, also cause material handling and size reduction issues, as well as wear in the mills and acidulation mixer. The presentation will also look at the enhancement of final products via the production of high grade specialist fertilizers such as high magnesium and high sulphur superphosphate.

The cadmium and heavy metal content of sedimentary phosphates are of great concern. This has seen industry raw material consumption shift towards igneous phosphates or the blending of phosphate rocks from different sources. While rock blending can successfully reduce the heavy metal content of superphosphates, it needs to be accompanied by careful process adjustments Click Here to download the complete article in pdf format as published by BCInsight Ltd in Fertilizer International Nov|Dec 2023, issue 517, pp. 53-57.
