There are some potash potentials in Iran. from which. the Garmsar deposit has
recently been explored. The paper
discusses the results of the characterization and beneficiation studies of low and high grade samples from Rahrahak region. The samples were identified by various methods. The main impurity was sodium choloride. The amount of insoluble materials. i.e. clay minerals. was low. Many floatation experiments were carried out in saturated brine. After optimization of the most significant parameters. a froth concentrate containing about 51% K and O.5% Na was
produced. A differential dissolution of NaCl found to be occurred during flotation process which caused the Na content of tailing reduced considerably.
