Abstract

The invention discloses an industrial production method of separating valuable elements from composite paragentic mineral of aluminum-vanadium-titanium-iron-silicon for cyclic utilization. The method comprises the following steps: employing the technique of gradient magnetic separation to separate aluminum-silicon-iron products, vanadium-titanium-iron products and sulfur concentrate from composite paragentic mineral of aluminum-vanadium-titanium-iron-silicon; carrying out flash suspension smelting on the aluminum-silicon-iron products to obtain ferrosilicon alloy and aluminum slag which is used as a raw material for production of alundum; employing the technique of rectilinearly movable bed prereduction-shaft furnace smelting to prepare the vanadium-titanium-iron products into vanadium iron intermetallic compounds and titanium slag. Smelting separation and flash suspension smelting and rectilinearly movable bed prereduction-shaft furnace smelting are combined in the method provided inthe invention, which enables the recovery rate of raw ores to be enhanced.

Description

technical field [0001] The invention relates to a method for separating minerals, more particularly, an industrialized production method for separating valuable elements from aluminum-vanadium-titanium-iron-silicon composite symbiotic ore for recycling. Background technique [0002] The feasibility of dressing and smelting of raw ore (gross ore) in different origins is not the same. Generally speaking, raw ore (gross ore) dressing and smelting can be roughly divided into two types. One is to obtain qualified iron concentrate and titanium concentrate that can be further processed in industry through ore dressing. Iron concentrate can be obtained through a certain amount of rich iron ore. Blast furnace smelting to obtain pig iron; titanium concentrate can be smelted through carbothermal reduction to obtain high-titanium slag, which can be further processed; another kind of raw ore (gross ore) with low grade and difficult to separate and smelt, it is difficult to obtain qualifi...
