“We are also very pleased to have commissioned the acid regeneration circuit, achieving acid recovery rates during HPA calcination of over 99.99 percent, as independently measured by CMI-UVK, which is superior to the 99.75% that was expected and is equivalent to 25x less acid loss than anticipated,” said Denis Primeau, Eng., Chief Engineer of Orbite Aluminae. “All of which further demonstrates the viability of using our proprietary process to produce smelter-grade alumina (SGA) at our proposed SGA plant.”


Any idea?
