Abstract
The present invention includes the following steps: sulfatizing roasting nickel ore concentrate in fluidized roasting furnace, then heating, strirring and leaching-out by using sulfuric acid solution, filtering, solid-liquid separating, stoving residue, high-temp. reducing, adding calcium oxide slagging constituent, and then smelting and obtaining crude nickelferrite, then adopting the processes of soda desulfurization and converting to remove impurity so as to obtain refined nickelferrite, then using yellow sodium iron vitriol method to remove iron from leach liquor, and producing electrolytic copper, then using chlorine oxidizing process to remove cobalt, and making the cobalt slag undergo the processes of dissolution and extraction to obtain cobalt powder or cobalt oxide, then making the residual solution undergo the processes of precipitation and separation, and using the precipitated nickel carbonate to produce electrolytic nickel, using precipitated basic magnesium carbonate to produce magnesium carbonate. The total recovery of nickel and copper is up to above 97%.
Description
The present invention relates to improvement to non-ferrous metal metallurgy technologies such as nickel, copper, cobalt, magnesium.
China's nickel resources is abundant, and wherein 86% is the nickelous sulfide mineral deposit, and association has copper, cobalt, magnesium, gold and silver, sulphur and platinum metals, can be for development and use.
Smelting for nickel ore concentrate has two kinds of pyrogenic process and wet methods at present.Pyrometallurgical smelting is about to nickel ore concentrate and is smelted directly into ice nickel, make electrolytic nickel through electrolysis again, its cost height, other non-ferrous metal such as magnesium, cobalt etc. do not reclaim: hydrometallurgy has been seen report abroad, nickel ore concentrate is soaked reduction extraction nickel by the sulfurization roasting leaching or with ammonia, but the nickel leaching yield is low.
Nickel is widely used in making stainless steel, steel alloy.Along with the development of steel-smelting technology, having seen has nickel oxide ore to carry out prereduction abroad, and the technology of smelting ferronickel report replaces producing stainless steel, steel alloy with expensive electrolytic nickel, nickel block or nickel powder again.The output proportion of western developed country sintering oxidation nickel and ferronickel accounts for more than 40%, and China still utilizes electrolytic nickel, nickel block or nickel powder to produce stainless steel, steel alloy.
From looking into new result, after leaching by sulfurization roasting by nickel sulfide concentrate, soak the technology of slag melting ferronickel and do not see that both at home and abroad reported in literature is arranged.
The object of the present invention is to provide and a kind ofly can improve the rate of recovery of non-ferrous metal by extracting nickel, copper, cobalt, magnesium in the nickel sulfide concentrate and making the technology of ferronickel, reduce production costs, economic benefit obviously increases.
The present invention realizes so in conjunction with the accompanying drawings.After being leached by sulfurization roasting by nickel sulfide concentrate, soak slag and be used for smelting ferronickel, immersion liquid is used to extract nickel, copper, cobalt, magnesium.
Concrete technology is: nickel ore concentrate carries out sulfurization roasting in fluidized roaster, makes nickel contained in the washed ore, copper, cobalt etc. change water soluble sulfate into.For making the abundant oxidation of iron, reach the purpose that selectivity leaches, and be lower than the decomposition temperature of single nickel salt, roasting is in that to contain oxygen higher, is 500-700 ℃ under the lower condition of maturing temperature and carries out.Then calcining is leached with the sulphuric acid soln heated and stirred, more after filtration, make solid-liquid separation.40% nickel and other non-ferrous metal are leached, and 60% nickel is stayed and soaked in the slag.
Soak the raw material of making smelting ferronickel after the slag drying.The smelting of ferronickel is a reduction process at high temperature.Can in blast furnace, rotary kiln or electric furnace, carry out.Soaking slag carries out prereduction and adds an amount of coke powder or coal and control reduction under 900 ℃ of temperature, furnace charge contacts with the furnace gas that contains carbon monoxide, carbonic acid gas, nickel oxide becomes metallic state with iron oxide reduction, adds the calcium oxide slag former of suitable proportion, produces thick ferronickel at 1550 ℃.Adopt the soda ash desulfurization, get smart ferronickel through the blowing removal of impurities again.Smart ferronickel can be 1650 ℃ of temperature lower mold, nickeliferous 20-40%, and sulfur-bearing is less than 0.02%.
At first with the yellow sodium ferrum vanadium process deironing, scum returns sulfurization roasting in immersion liquid.Solution electrodeposition copper powder after the deironing is produced electrolytic copper.After removing cobalt with chlorine oxidation again, the cobalt slag is produced products such as cobalt powder or cobalt oxide through dissolution extraction.Solution carries out nickel, magnesium separation through two sections nickel precipitator method again.Sedimentary nickelous carbonate is produced electrolytic nickel through dissolving.Sedimentary magnesium basic carbonate is used to produce magnesiumcarbonate.Hydrometallurgic recovery copper, cobalt, nickel are moulding process, are not repeated at this.
Technology provided by the invention reaches more than 97% the total yield of nickel, copper.The melting of ferronickel reduces production costs for we have opened up a new approach, and economic benefit obviously increases.
