Prado & Associates Pradotec
Engineers to the World's Chemical Industries

WHO WE ARE:

A firm of chemical and metallurgical consulting engineers with experience in the chemical, mineral and metals industries. We have particular expertise in the Caron Process which uses ammonium solutions for the extraction and recovery of non-ferrous metals. We also have expertise in the extraction and recovery of uranium using solvent extraction and ion exchange technologies.  Our engineers, many of whom are members of  The Metals Society (TMS) and the American Institute of Chemical Engineers (AIChE), are dedicated to the chemical and metallurgical industries and collectively offer many years of experience. Our organization includes our sister company Prado Technology Corp. who is engaged in technology transfer.

WHAT WE CAN DO FOR YOU:

We can provide process development, technology transfer, basic engineering, pilot plants, detailed engineering, complete plant design, project management, equipment procurement, and construction supervision for the following:

  • Mineral Beneficiation, including phosphate
  • Ammonia-ammonium carbonate leaching technology (Caron Process) for the production of nickel and cobalt.
  • Ammonia-ammonium carbonate leaching technology for the recovery of secondary smelter dusts, including EAF. This includes recovery of valuable metals such as zinc, lead, cadmium, copper, and tin. This technology will convert EAF dusts ("K061" wastes) into valuable products.
  • Hydrometallurgy
  • Pyrometallurgy
  • Recovery and recycling of nickel, cobalt, copper, zinc, gold, silver, lead, uranium, cadmium
  • Waste treatment and environmental conservation
  • Recovery of uranium from phosphoric acid. Production of uranium yellowcake and black cake.

HOW WE FUNCTION:

Our engineering staff can develop the technical solutions to your problems in the area of minerals and metals processing. One of our senior engineers will be assigned to lead the project team from completion to end, thus assuring continuity and responsiveness. We can provide process development, followed by basic engineering, detail design equipment procurement, and project management. All our design is done on AutoCAD. All of our specialist engineers are licensed professional engineers in Florida, many other states of the USA and in the European Union. Our work can be done in association with our sister company Prado Technology Corp.
