Prospech (ASX:PRS) executed a fixed‑price contract with ANSTO Minerals, a business of the Australian Nuclear Science and Technology Organization (ANSTO), to undertake pre‑leaching and acid baking/leaching test work on a rare earth elements concentrate from the Korsnäs project in Finland, according to a Friday Australian bourse filing.
Testing will begin after the delivery of around 20 kilograms to 30 kilograms of higher‑grade concentrate produced from Prospech's bulk flotation program at CORE Resources.
The firm seeks to study the extraction performance and inform the Korsnäs process flowsheet.
