Abstract
The invention belongs to field of metallurgy, are a kind of raw materials of synthesizing carbonyl nickel, are configured by the material of following mass fraction, dilval 90%~95%, copper powder 3%~8%, sulphur powder 1%~2%；Configuration process are as follows: copper powder, the sulphur powder measured by said ratio is sequentially added in the molten condition ferronickel that will be come out of the stove, copper powder, sulphur powder are that process is had bad luck in sedimentation after being added, sedimentation has bad luck time control in 0.5h~1h, sedimentation carries out water quenching operation after having bad luck, water quenching pelletizes granularity control in 2mm~10mm, it is dried after water quenching, flash-off time is controlled in 2h~5h.The beneficial effects of the present invention are: laterite pyrometallurgical smelting product coarse ferronickel is expanded the serial carbonyl nickel product such as carbonyl iron dust, carbonyl nickel powder, nickel rondelle for becoming high added value to vapometallurgy field from stainless steel smelting field.
Description
Technical field
The invention belongs to metal metallurgy smelting fields, are related to a kind of raw material of synthesizing carbonyl nickel.
Background technique
In recent years, global nickel sulfide ore mine continues to increase exploitation dynamics, and vulcanization nickel resources is made to face exhaustion, economical to meet
Develop the demand to nickel, the emphasis of development of resources is aimed at the laterite ore resources of rich reserves by global nickel industry, currently, it is handled
There are two big process flows, i.e. thermal process and wet processing.Wherein, thermal process production capacity is big, and product purpose is single, almost all
For the smelting of low side stainless steel, production capacity has been approached saturation.Carbonylation metallurgical technology has the technological merits such as selective reaction, can be with
Effectively ferronickel is separated with other metals, but the ferronickel of existing ferronickel technique output is than great, synthesizing carbonyl nickel, carbonyl iron
Reaction rate is slow, or even does not react.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of raw material of new synthesizing carbonyl nickel, for synthesizing carbonyl nickel,
Carbonyl iron solves the problems, such as that carbonylation reaction is not easy to carry out.
The invention adopts the following technical scheme: a kind of raw material of synthesizing carbonyl nickel, is configured by the material of following mass fraction
It forms, dilval 90%~95%, copper powder 3%~8%, sulphur powder 1%~2%；Configuration process are as follows: in the molten condition that will be come out of the stove
Copper powder, the sulphur powder measured by said ratio is sequentially added in ferronickel, has bad luck process after copper powder, sulphur powder addition for sedimentation,
Sedimentation has bad luck time control in 0.5h~1h, and sedimentation carries out water quenching operation after having bad luck, water quenching pelletize granularity control 2mm~
10mm dries after water quenching, and flash-off time is controlled in 2h~5h.
The beneficial effects of the present invention are: expanding laterite pyrometallurgical smelting product coarse ferronickel from stainless steel smelting field to gas
Change field of metallurgy, becomes the serial carbonyl nickel product such as carbonyl iron dust, carbonyl nickel powder, nickel rondelle of high added value.Configuration process
Simply, easy to operate.
