TORONTO, November 30, 2011 /PRNewswire/ --
Verde Potash Plc (TSX-V: "NPK") ("Verde" or the "Company") has successfully operated a continuous rotary kiln pilot plant to produce Potassium Chloride ("KCl"), the conventional potash fertilizer. Verde has engaged SRK Consulting (U.S.), Inc. ("SRK") to complete a review of capital and operating costs and should be in a position to reveal results in Q1 2012. This achievement marks a significant possible opportunity for Brazil, one of the world's largest importers and consumers of KCl, to supply more of its potash requirements from its domestic resources.
Verde controls a very large potash resource amenable to strip mining and strategically located in Minas Gerais State, Brazil (see press release August 3, 2011). The Company's current potash resource could support a six million tonnes per annum KCl production scenario for over twenty years, though Verde is considering a scalable production strategy.
The current selling price for KCl in Brazil's Cerrado is US$660/tonne. Brazil imported 6.4 million tonnes of KCl from January to October this year (source: Associacao Nacional para Difusao de Adubos "ANDA").
Verde has made significant progress in deriving an economic scalable production flow sheet for KCl. SRK, Hatch Consulting, GEA Messo, FLSmidth and Hazen Research (the "Engineering Consortium", see below for further details) have assisted the Company in overcoming foreseeable technological and operational challenges by using long established rotary kilns and evaporation/crystallization equipment for this new application.
During this month, the Company successfully operated its pilot plant's rotary kiln validating the production flow sheet. In two tests, KCl was produced continuously for thirty and twenty hours. The kiln feed rate was 130kg per hour. As a result of this progress, the Company has filed two additional patents relating to KCl production.
Given these successes, the Company has commissioned SRK to complete a Preliminary Economic Assessment ("PEA"). SRK is working closely with the rest of the Engineering Consortium to estimate operating and capital costs for KCl production based on the flow sheet developed by Verde and the Engineering Consortium.
Verde initiated KCl production studies for its potash rock in 2008. Over the last three years the Company undertook hundreds of tests pursuing a simple production flow sheet that relied on long proven production technology as well as abundantly and readily available reagents. In 2010, the Company announced a first patent filing as a result of a research agreement with the University of Cambridge and Professor Dr. Derek Fray. In 2011, the Company assembled the Engineering Consortium to advance the project. Below is a summary of the work completed throughout 2011 leading Verde to this point:
- Verde, Brazil: Scale up and optimization tests completed at the Company's laboratory in Brazil;
- University of Cambridge, U.K.: Further bench tests concluded.
- Hazen Research, Colorado, U.S.: Work began by Hazen's commercial laboratory on research and development to continue scale up work, completing more than 300 tests and more than 6,000 check points assayed in Q3;
- Verde, Brazil: Advances on reagent optimization.
- Hazen Research, Colorado, U.S.: Satisfactory results obtained from scale up work;
- Discussions with equipment manufacturers regarding equipment specifications and use for KCl production;
- FLSmidth, Pennsylvania, U.S.: engaged to test heat consumption;
- GEA Messo, Germany: engaged to test and optimize leaching/evaporation/crystallization;
- Hatch Consulting, Ontario, Canada: engaged and contributed on the review of the results.
- Engineering Consortium: Flow sheet finalized;
- SRK: Preliminary Economic Assessment with an updated National Instrument 43-101 technical report to be completed by Q1 2012.
Cristiano Veloso, President and CEO said: "We congratulate Pedro Ladeira, VP Engineering, and the Engineering Consortium for their outstanding achievement. Verde's work to convert our at-surface potash resources into potash fertilizer has the potential to decrease Brazil's import dependency on a commodity essential for feeding the world's growing population of seven billion."
Verde's engineering team has also continued to develop its ThermoPotash product. Using the Company's same pilot plant kiln, the team completed work to transfer the pellet making process from pre-calcining (in the kiln) to a post-calcine step. This modification to the flow sheet reduces heating requirements and water consumption, and produces better performing pellets. In the improved process flow sheet the kiln is fed with powder as opposed to wet pellets.
The Company has also tested the process of air cooling the product from the kiln using the same type of dryer employed by the cement industry. This process adjustment reduces heat consumption by pre-heating air entering the kiln with hot gases resulting from cooling the material with air. In the original flow sheet, the kiln emptied its contents into tanks of water to cool the product. FLSmidth has also undertaken independent tests to verify achievements and propose equipment.
Verde's Brazilian pilot plant facility has been successfully re-configured for the noted changes and has produced over 60 tonnes of ThermoPotash. The changes have reduced heat input and the process' use of water. Verde has also operated a leased semi industrial plant where it produced 70 tonnes of ThermoPotash.
Cristiano Veloso, President and CEO said: "We are pleased with the successful conclusion of our pilot plant tests for ThermoPotash production. Pedro Ladeira's extensive cement production experience was fundamental in improving the original production flow sheet".
