There are numerous physical and chemical separation methods for reducing iron content in
feldspar ores. Generally, while -500+75 µm sized feldspar ores beneficiate by physical and
physicochemical separation methods such as magnetic separation and flotation, -75 µm sized ones
are discarded as slime sized tailings. In these research; oxalic, citric and glycolic acids which are
principal organic acids to be used in leaching were used in these slime sized (-75 µm) feldspar ores in
order to reduce iron amount. Temperature, pulp density, leaching time and acid molarity parameters
were investigated by applying factorial design ANOVA-Yates test technique. As a result of the tests,
effective parameters were determined and discussed. The best result was obtained as 67.90 % iron
removal by using oxalic acid.
