Abstract
The present invention relates to a flash smelting metallurgical technology for copper and nickel sulfide ore concentrate. In the technology, a flow channel is arranged between a flash smelting furnace and a top-blowing smelting furnace with a molten pool; copper and nickel sulfide ore concentrate is in a suspended state to be oxidized by oxygen-enriched air in the flash smelting furnace first to obtain copper matte or nickel matte; then the copper matte or nickel matte directly enter the top-blowing smelting furnace with a molten pool in a molten state to be further oxidized by oxygen-enriched air or pure oxygen to obtain raw copper or bessemer matte. In the metallurgical technology of the present invention, a smelting method of a flash furnace having the advantages of high efficiency and low energy consumption in smelting is combined with a blowing smelting method of a top-blowing smelting furnace with a molten pool having the advantages of simple processes and less investment in blowing smelting in order to achieve the large scale and the economic building and running of copper and nickel smelting plants.
Description
Technical field
The present invention relates to the nonferrous metallurgy field, especially a kind of copper, nickel vulcanised ore concentrate flash smelting metallurgical technology.
Background technology
At present, the smelting of copper, nickel vulcanised ore concentrate mainly contains following three kinds of forms: 1, flash stove melting-→ PS bessemerizes, and copper, nickel vulcanised ore concentrate enter PS and bessemerize after the melting of flash stove, many PS converters of this arts demand are blown, and PS bessemerizes and has low latitude SO
2Shortcomings such as seriously polluted and processing power is limited; 2, flash stove melting-→ blowing of flash stove, copper, nickel vulcanised ore concentrate enter the blowing of flash stove, and there are the shortcoming that metallurgical energy utilization rate is low and Production Flow Chart is long in the blowing of flash stove after the melting of flash stove; 3, top-blown bath smelting furnace melting-→ blowing of top-blown bath converting furnace, copper, nickel vulcanised ore concentrate enter the blowing of top-blown bath converting furnace, and there are shortcomings such as production efficiency is low, energy consumption is big in the melting of top-blown bath smelting furnace after the melting of top-blown bath smelting furnace.
Summary of the invention
Purpose of the present invention be exactly with at the flash stove melting method that has high-level efficiency, less energy-consumption aspect the melting with flow process is simple, the top-blown bath stove converting method of less investment is combined having aspect the blowing, a kind of copper, nickel vulcanised ore concentrate flash smelting metallurgical technology are provided.
Copper of the present invention, nickel vulcanised ore concentrate flash smelting metallurgical technology are between flash smelting furnace and top-blown bath converting furnace chute to be set, one end of chute links to each other with the flash smelting outlet of still, the other end links to each other with the top-blown bath converting furnace, copper, nickel sulfide ore concentrate are through after the depth drying, at first in flash smelting furnace, be suspended state by the oxygen-rich air oxidation, obtain copper matte regulus or nickel matte, liquid then copper matte regulus or nickel matte directly enter into the top-blown bath converting furnace through chute and are the liquation state by oxygen-rich air or further oxidation acquisition blister copper of purity oxygen or Bessemer matte.
Copper of the present invention, nickel vulcanised ore concentrate flash smelting metallurgical technology will have high-level efficiency, a less energy-consumption aspect melting flash stove melting method with have aspect blowing that flow process is simple, the top-blown bath stove converting method of less investment is combined, with the maximization that reaches copper, nickel smeltery and most economical construction and operation.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Copper of the present invention, nickel vulcanised ore concentrate flash smelting metallurgical technology is between flash smelting furnace 1 and top-blown bath converting furnace 2 chute 3 to be set, one end of chute 3 links to each other with flash smelting furnace 1 outlet, the other end links to each other with top-blown bath converting furnace 2, copper, nickel sulfide ore concentrate is through after the depth drying, at first in the fixed flash smelting furnace of routine, be suspended state by the oxygen-rich air oxidation, obtain liquid copper matte regulus or nickel matte, liquid then copper matte regulus or nickel matte directly enter into conventional fixed top-blown bath converting furnace through chute and are the liquation state by oxygen-rich air or further oxidation acquisition blister copper of purity oxygen or Bessemer matte.
Claims (2)
1, a kind of copper, nickel vulcanised ore concentrate flash smelting metallurgical technology, it is characterized in that: copper, nickel sulfide ore concentrate are through after the depth drying, earlier in flash smelting furnace, be suspended state by the oxygen-rich air oxidation, obtain liquid copper matte regulus or nickel matte, the top-blown bath converting furnace that liquid then copper matte regulus or nickel matte directly enter into through chute is the liquation state and is obtained blister copper or Bessemer matte by oxygen-rich air or the further oxidation of purity oxygen.
2, according to the described copper of claim 1, nickel vulcanised ore concentrate flash smelting metallurgical technology, it is characterized in that: between described flash smelting furnace (1) and the described top-blown bath converting furnace (2) chute (3) is set, one end of chute (3) links to each other with flash smelting furnace (1) outlet, and the other end links to each other with top-blown bath converting furnace (2).
