Embodiment 1

[0022] 30 grams of raw materials were charged into a corrosion-resistant tubular reactor, including Ni (50%), Fe (7.2%), Cu (15.7%), and Co (1.2%). The particle size of the raw material is 45-60 mesh. When carbon monoxide containing 0.1% hydrogen sulfide is introduced, and the reaction conditions are at a temperature of 200° C. and a pressure of 7.0 Mpa for 10 hours, the extraction rate of nickel is 99.2%.

Embodiment 2

[0024] 30 grams of raw materials were charged into a corrosion-resistant tubular reactor, including Ni (65%), Fe (6.8%), Cu (13.5%), and Co (1.1%). The particle size of the raw material is 5-15 mesh. When carbon monoxide containing 0.5% hydrogen sulfide is introduced, and the reaction conditions are at a temperature of 200° C. and a pressure of 4.0 Mpa for 12 hours, the nickel extraction rate is 98.7%.

Embodiment 3

[0026] 30 grams of raw materials were charged into a corrosion-resistant tubular reactor, including Ni (70%), Fe (6.4%), Cu (11.5%), and Co (1.3%).

Abstract

The present invention is an oxo synthesis process of preparing cabonyl nickel from coarse nickel ore. The synthesis process has coarse nickel mineral as direct reactant, CO as reactant gas and H2S gas as catalyst, and in the operation conditions of 160-200 deg.C reaction temperature, 3.0-8.5 MPa reaction pressure and 8-12 hr reaction time, cabonyl nickel is produced with nickel extracting rate as high as 98%. The present invention has short reaction period, no need of treating reaction material and simple reaction process.

Description

Technical field [0001] The invention relates to a method for preparing nickel carbonyl by carbonylation of coarse ore nickel. Background technique [0002] As an important non-ferrous metal, nickel is widely used in various fields such as chemical industry, construction, military, steel industry, electronics industry, and new materials. As early as 1883, there was a patent report on the separation of nickel. In terms of nickel purification, electrolysis was the main method at first, but the purity of electrolytic nickel was limited by the purity of raw materials. With the development of science and technology, the quality requirements for nickel are becoming more and more stringent. Electrolytic nickel can no longer meet the requirements of science and technology in some fields. Under the demand of this kind of science and technology, a process for refining nickel by carbonylation has recently been developed. The nickel carbonyl produced by this process can be decomposed to produ...
