As shown in Fig. 2 being the method flow schematic diagram using the system coproduction dilval shown in Fig. 1 and magnesium metal.Bag
Include following steps：
(1) material mixing
Silicon magnesium types lateritic nickel ore, reduction coal, additive are crushed to granularity respectively and are less than 3mm, send according to certain ratio
Enter in mixing device 100, after three kinds of material mixing, obtain compound.In the embodiment of the present invention, control the matter of three kinds of material mixing
Amount ratio is：Silicon magnesium types lateritic nickel ore：Reduction coal：Additive=100：5～25：3～15.
In the embodiment of the present invention, in above-mentioned silicon magnesium types lateritic nickel ore：Nickel content is that (wt% is quality hundred to 0.5～3.0wt%
Fraction), content of magnesia is not less than 20wt%.Inventor finds, the dilval high in order to obtain grade, it usually needs adopt
The higher lateritic nickel ore of nickel content.When the content of magnesia in silicon magnesium types lateritic nickel ore is too low, the magnesium in the ferronickel slag obtaining
Content is relatively low, does not possess and puies forward magnesium value.
Inventor finds, if the addition of reduction coal is too low, can affect follow-up silicon magnesium types lateritic nickel ore and carry out reducing-melting dividing
The effect of reaction；If the adding too much of reduction coal, it is not improved the effect of technical target of the product, and coal resource can be caused
Waste, improve production cost.
In the embodiment of the present invention, additive can be selected from alkali metal oxide, alkali metal salt, alkaline earth oxide, alkali
Earth metal salt.Inventor finds, in the reduction process of silicon magnesium types lateritic nickel ore, the additive of mentioned kind can be from magnesium Fructus Canarii albi
Displace NiO in stone or fayalite, to improve the activity of NiO, thus the temperature of reducing and smelting can be significantly reduced, promote reduction
The carrying out of reaction, improves silicon magnesium types lateritic nickel ore and carries out reducing-melt a point effect for reaction.Inventor also finds, the use of additive
Amount is too high or too low, all can reduce the reduction effect of the middle nickel of silicon magnesium types lateritic nickel ore.
(2) reduction-molten point melting
The compound that above-mentioned steps are obtained is sent in reduction-molten separating device 200 via compound entrance 201 and is carried out also
Former-molten point of melting, obtains dilval and ferronickel slag.
Wherein, dilval is collected via dilval outlet 202 and is discharged.
Inventor finds, in the ferronickel slag that this step obtains, the content of magnesium oxide, in more than 20wt%, can serve as extracting
The raw material of magnesium metal.

Degree is maintained in the range of 13.3～133.3Pa, and the response time is 6～12h.This step can get magnesium steam and tailings.
In this step, ferronickel slag, ferrosilicon, the mass ratio of quick lime is controlled to be 100：10～30：50～100.
Because when ferronickel slag is discharged from reduction-molten separating device 200, temperature is higher, in vacuum reduction smelting apparatus 300,
Ferrosilicon can under the high temperature conditions in reduced nickel scum MgO, thus producing magnesium vapor.
In this step, the SiO that vacuum reduction reaction produces2Dicalcium silicate can be generated with the CaO reaction in quick lime, thus
The temperature of reduction by ferrosilicon MgO is greatly lowered, improves the percent reduction of magnesium.The dicalcium silicate generating is the main component of tailings,
This tailings can be used as the cement raw material of high-quality.
(4) prepare refined magnesium
The magnesium vapor that above-mentioned steps are obtained is sent in condensation purifier 400 via magnesium vapor entrance 401, carries out cold
Solidifying, refine, can get refined magnesium.
In this step, first magnesium vapor is condensed when temperature is 500～600 DEG C, then to condensed solid-state
Crude magnesium carries out refine.Because the vapour pressure of the steaming pressure ratio wherein impurity of magnesium is high, heating in distillation refine steaming pot contains impurity
Crude magnesium when, magnesium therein preferentially distils, thus obtaining refined magnesium.
