1. Phosphate Processing

Phosphate Processing

We offer phosphate processing solutions from ore to purified phosphoric acid and salts.

Tenova Advanced Technologies (TAT) offers differentiated, project-specific process technologies based upon decades of research, equipment design and project execution. Advanced solutions include Solvent Extraction (SX) and Electrowinning (EW) for the mining and chemical industries, membrane circuits, in-house state-of-the-art R&D facilities, expertise in minerals beneficiation as well as phosphate processing from ore to purified phosphoric acid and salts.

At its core, TAT offers phosphate beneficiation process development and proprietary technologies for the purified phosphoric acid industry, both complemented by in-house laboratory and pilot plant facilities.

Phosphate Beneficiation

TAT provides the full suite of technologies for the beneficiation of phosphate rock. Project services range from process development through to feasibility studies and complete turnkey solutions, and are available for:

  • Sedimentary and igneous ore types
  • Carbonaceous and/or siliceous gangue
  • Terrestrial and marine deposits
  • Low grade phosphates
  • High impurity phosphates
  • Reclamation of phosphate from tailings

Our R&D facility is well equipped to handle a wide range of phosphate ore types catering to both wet and dry beneficiation laboratories together with modern analytical technologies. We also pride ourselves upon our in-house laboratory and pilot plant facilities for purified phosphoric acid, SX and mineral beneficiation test work.

Purified Phosphoric Acid

TAT provides the full suite of technologies required for the production of phosphoric acid from phosphate rock and wet process phosphoric acid, including the SX stages, acid purification and concentration; and to produce high quality food or technical grade phosphoric acid.

All data acquired during the process development stage is continuously monitored and improved upon so as to ensure reliable plant design information. Some of the factors that are considered include:

  • Pre-treatment: impurity removal such as sulphates, cadmium, fluorides and arsenic
  • Purification: using proprietary SX processes and selection of the optimal solvent for the purification stage
  • Post-treatment: bringing the product to its final specification through concentration, solvent recovery and the reduction of total organic carbon

Project Implementation

Based upon years of experience and know-how, we have developed and refined a comprehensive step-by-step approach for project development, ensuring the all-round fulfillment of project requirements and the ultimate successful delivery of the project.
