Abstract
The invention discloses a kind of molybdenum-iron silicothermic process smelting process, the method is comprised the following steps：A, the molybdenum ore sand of 150-200 parts according to the mass fraction, 50-70 parts of ferrosilicon powder, 40-60 parts of brown iron oxide, 8-12 parts of lime, 4-8 parts of aluminum shot are well mixed；B, well mixed material is put into reacting furnace carries out autothermal reaction；C, will reacted product cool down after carry out molybdenum-iron and slag and separate to can obtain molybdenum-iron finished product.A kind of molybdenum-iron silicothermic process smelting process of the present invention, by with fluorite in the traditional molybdenum-iron silicothermic process smelting process of lime substitution, the generation of fluorine class pollutant effectively can be thoroughly avoided, while effectively reducing cost of material and improve product quality, the method environmental protection and economy, progressive meaning is notable.
Description
Technical field
The present invention relates to a kind of molybdenum-iron production method, more particularly to a kind of molybdenum-iron silicothermic process smelting process.
Background technology
Silicothermic process smelting process is now widely used molybdenum-iron preparation technology, due to generally needing to be used as additive using fluorite in technique, therefore easily cause fluorine contaminant generation and severe contamination destruction natural environment, hardly consistent with current environmental requirement.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of molybdenum-iron silicothermic process smelting process for being prevented effectively from fluoride pollution.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of molybdenum-iron silicothermic process smelting process, comprises the following steps：A, the molybdenum ore sand of 150-200 parts according to the mass fraction, 50-70 parts of ferrosilicon powder, 40-60 parts of brown iron oxide, 8-12 parts of lime, 4-8 parts of aluminum shot are well mixed；B, well mixed material is put into reacting furnace carries out autothermal reaction；C, will reacted product cool down after carry out molybdenum-iron and slag and separate to can obtain molybdenum-iron finished product.
Preferably, the granularity of the molybdenum ore sand is 1-2 millimeters.
Preferably, the content of calcium oxide is more than 90% in the lime.
Compared with prior art, a kind of molybdenum-iron silicothermic process smelting process of the present invention, replace fluorite in traditional molybdenum-iron silicothermic process smelting process by with lime, effectively can thoroughly avoid the generation of fluorine class pollutant, cost of material is effectively reduced simultaneously and improves product quality, the method environmental protection and economy, progressive meaning is notable.
