Optimizing and modelling of a partially acidulated

The selective recycle model for a generalized NCD was effectively used to simulate the RTD's in the comminution of phosphate rock and in the acidulation and granulation processes. This resulted in the optimization of the operations of the main processing units (i.e. the ball mill in the comminution of phosphate rock and the granulator in the processing of phosphate rock into PAPR). The PAPR

Dry Comminution of Hard-rock Phosphate Ore |

After being approached by EuroChem to develop a dry comminution process based on VRM technology, Loesche performed extensive test work at its research center and won the contract. Since completion of the commissioning in February 2016, the 650,000-mt/y phosphate rock grinding plant, engineered, delivered and assembled by Loesche, operates to EuroChem's complete satisfaction.

Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-, magnetic separation or flotation. By comparison, the average phosphorus content

Ore Processing Challenges in Gold Operation

Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. When the target grind is not achieved (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue. Over-grinding does not have a significant benefit to gold recovery but

A Tailor Made Approach for the Beneficiation of Phosphate Rock

Phosphate rocks from different deposits possess a wide range of properties related primarily to the geological origin of the phosphate. In parallel, beneficiation methods for phosphate rock are finite and include: comminution and size separation (crushing, grinding, attrition, screening and classification), mineral separation (flotation, gravity and magnetic separation) and ocassionally
