Abstract

The invention provides a kind of dry method withdraws the nickel the production method, it is take the petroleum majoring in engineering industry expelling spent catalyst, the waste sweetening agent or withdraws Gao Linhan after the aqueous method which the vanadium molybdenum expels the vanadium low nickel residual second pollutant as nickel raw material smelting to produce the ferronickel the technology, it according to the fertilizer conformity, the weighing mixture, the reducing smelting and oxidizes fining the step to carry on, in the dual alkali degree CaO% / SiO2% approximately 0.8~~1.8 scope, with the coke, the ferrosilicon makes the reducing agent to carry on the reducing smelting to remove 60~~70% phosphorus, again in in the slag dual Alkali degree CaO% / SiO2% approximately 1.2~~3.5 scope, selects the oxygen - iron ore union oxidation method, May cause 99% above the phosphorus and 98% above vanadium union produces CaO.P2O5 and CaO.V2O5 enters the slag, after refines the qualified ferronickel product, realizes from Gao Linhan in the vanadium nickel waste material the short flow, the low cost, the industry withdraws the nickel the goal, has the remarkable economic efficiency and the social environmental protection effect.

Description

Technical field:

[0001] The invention relates to a smelting technology for separating and extracting metals by means of fire, which belongs to the technical field of metallurgical engineering, in particular to a production technology for smelting nickel-iron alloys from high-phosphorus vanadium-containing nickel waste discarded in the petrochemical industry, specifically a kind of The production method of nickel extraction by fire method. Background technique:

[0002] As we all know, nickel is an important alloying element in the metallurgical industry. Due to the unique properties of nickel metal, it is widely used in the production of special steel, high-temperature alloys, precision alloys, heat-resistant alloys, shape memory alloys, hydrogen storage alloys, electronic and electrical batteries, and magnetic materials. It has a very wide range of applications in many technical fields such as sensors, chemical catalysts, etc. Nickel alloy materials occupy a very important ...
