The low temperature molten salt method was used to extract potassium from K-feldspar ore, and some related factors including mass ratio between NaNO 3, NaOH, H 2 O and K-feldspar ore, particle size of K-feldspar ore, reaction temperature and time were investigated, respectively. In addition, the optimum condition for this method was determined by a series of condition experiments.
The bauxite ore is crushed and finely ground.It is roasted to convert ferrous oxide to ferric oxide. The roasted ore is digested with sodium hydroxide solution at 150'C. When alumina is dissolved in the solution, the impurities such as iron oxide and titanium oxide are left behind. The filtrate is treated with freshly prepared aluminium hydroxide.
