Method for leaching rubidium, potassium and aluminum from rubidium-containing mica ore

The invention relates to a method for leaching rubidium, potassium and aluminum from a rubidium-containing mica ore. The method comprises the following steps that the rubidium-containing mica ore is mixed with concentrated sulfuric acid and subjected to a curing reaction, and thus a cured material is obtained; the cured material is reduced and roasted, and thus roasted sand and flue gas are obtained; the roasted sand is leached through water, and thus a leaching solution and leaching slag which contain rubidium and potassium are obtained; and the leaching slag is leached through an alkaline aqueous solution, and thus a leaching solution containing rubidium, potassium and aluminum is obtained. Synergistic extraction of potassium, aluminum and rubidium can be achieved, and the method has the beneficial effects that consumption of an acid/alkali reagent is less, energy consumption is low, the output quantity of waste slag is small, and the impact on the environment is small. 本发明涉及种从含铷云母矿中浸出铷钾铝的方法，包括以下步骤：将含铷云母矿与浓
