Abstract

The invention discloses an internal-heating light metal extracting device with an automatic material lifting function and an internal-heating light metal extracting method. The device comprises a reaction furnace chamber, the upper end of the reaction furnace chamber is fixedly connected with a metal crystallization chamber, and a lift is arranged at the lower end of the reaction furnace chamber. The lift drives reaction materials to move up and down in the reaction furnace chamber. It can be guaranteed that metal vapor is all crystallized in a crystallizer, and the crystallization efficiency and the metal yield are increased; a resistance radiation body makes contact with the reaction materials at a short distance, the thermal efficiency is high, the temperature rise rate is high, the reaction speed is high, and energy is saved; the structure is simple, and the cost is lower; the temperature in the metal crystallizer can be controlled by adjusting the height of a gas distributor, changing the thickness of a fireproof plate on the upper portion of the reaction furnace chamber, changing the height of the resistance radiation body in the reaction furnace chamber and lifting the whole device through spiral spring fasteners, and therefore the crystallization temperature of the gas-state metal vapor is controlled; the device is not only suitable for production of light metal, but also purification of metal or light metal extraction from low-grade ore and red mud.

Description

Technical field: [0001] The invention relates to the technical field of light metal preparation, in particular to a device and method for extracting light metal by internal heating that can automatically lift materials. Background technique: [0002] The production of light metals can generally be made by molten salt electrolysis. For some light metals with high vapor pressure, such as lithium, magnesium, calcium, etc., vacuum metallurgy can also be used to extract them. Taking metal magnesium as an example, among the vacuum metallurgical methods of magnesium, the method of vacuum thermal reduction of silicon thermal or aluminothermic metal is the most widely used, and the most widely used reducing agent is ferrosilicon alloy. The calcined product of a mixture of limestone and limestone, this method is called silicothermal reduction method. For some low-grade ores and red mud with high magnesium content, such as low-grade boron-magnesium ore, boron-magnesium iron ore and bo...
